- 204ps Bi-Turbo CXEB T6 Engine & Turbo problems -

Looks like im the latest patient of the CEXB engine issues.

(possibly the 2016-2018 range as there is a mention that the CXEB Block etc was revised in 2019)

(the CXEC 199ps Bi-Turbo was released 2019> and revised )


in sort it looks like its either Turbo or Engine failure.

here is some background:

******************************************************************
204ps Bi-Turbo CXEB Engine & Turbo problems:








******************************************************************

update. . . 4months later. - on my 6year old 2018 CXEB 80k miles van.

oil usage test under the TPI below failed. (used for than 0.5L per 1000km)

compression test across all cylinders failed. (tested at 15bar - fail point is 19bar)

"new long-block engine + cat + dpf + lambda sensor" all fitted by VW under the ALL-IN extended warranty (around £20k worth of work)

thank god for the extended warranty and me catching the symptoms early.
it took 4 months for the whole process, but VW garage gave us a loan van for the duration and VW ALL-IN picked up the whole bill.

so im now thinking that the CXEB engines maybe prone to TWO possible high oil use problems,

1# one being the Bi-Turbo (small) bearing failing - causing oil ingestion via the charge cooler into the inlet an burned in the cylinder, then clogs the CAT, DPF. - the VW tech said that this can be witnessed with a borescope showing wet oil in the induction path and inlet manifold, and also wet in all four cylinders.

the VW OEM repair is :

new Bi-Turbo,
new CAT,
new DPF,
new Lamda probe.



+++


2# the Bore/Piston wear, that the TPI covers (TPI - 2061290/6) - which the VW tech says can be witnessed with wet oil one or more cylinders, and not all four as id assumed, he said the chances were that one cylinder will be leaking oil, showing as wet, where the other will show dry, he also said that a compression test will show the weak cylinder, the wet oil and carbon deposit will also clog the injector head, which leads to a miss-fire on that cylinder. ( basically what i had)

the TPI states a guided fault finding, which calls for the oil to be drained and weighed. then replaced, then 500 odd miles to be driven, then the oil to be drained and weighed again.

if the engine shows that the oil usage is more that 0.5L per 1000km then its a fail and repair required.

the further investigation required is to compression test the cylinders (25-32bar for a new engine - 18bar wear limit)

borescope the cylinder walls looking for worn walls, and possibly measuring the cylinder diameters to so excessive wear.

the repair is :

new Long Block Engine ( Block, pistons, crank, head, cams etc )(but not accessories like EGR, Turbo etc)
new CAT,
new DPF,
new Lamda probe.

TPI - 2061290/6

CXEB excessive oil consumption . . over 0.5L per 1000km

+++++


New long block engine from VW roughly priced at 12-15k for parts, then 5k labour according to the tech that done the recovery on our van.

We've had full warranty, and currently have the all-in warranty, so let's hope it all works out.

+++++

this is what mine seems to be doing, using oil that is getting around the piston rings into the combustion chamber, due to the worn bores,

this also has low compression, so power is starting to gradually drop off,

the engine is starting to hard start when cold - due to low compression,

and starting to cold start miss-fire, due to contaminated injectors from the oily carbo deposits.

also the REGEN will be more often as the CAT & DPF start to clog with oil deposits - that cant be burned off with REGENS.

unchecked - this situation will worsen until the DPF clogs causing very high back pressure in the engine which can cause the turbo bearing to dry and fail, and ultimately ending in a engine non run / non start. at which point you will need the whole lot . . . Engine,turbo,cat,dpf,lambda probe etc etc etc.

.

@Komboss "Well. I have same problem. Finally decided to remove engine and strip off. We found bore cilinders worned 0,3mm off the nominal size. Middle piston ring unable to move at all. Baddly stuck of carbon. At this moment i do rebuild all engine. Just stuck with balance shaft which i cant find anywhere info how to do a timing them. If someone knows please reply."

@driftingaway - "
Same old story.
2016 206 Caravelle. 59,000 on the clock.
Bought from main dealer in January, oil light came on within 800 miles. I've since put 8 litres of oil in.
Finally got the oil consumption test done - they filled it, then I drove for 625 miles then returned to have the oil measured.
The oil light came on after 604 miles.
VW has confirmed it's a new engine job, but they're only stumping up 50% on goodwill.
3rd party warranty has refused to help deeming it "wear and tear"
Just waiting to hear back from the dealer on what else they can "do for me", in their words..."

#3 other cause and effect seems to be,

oil getting into the turbo vanes and overheating them causing the turbo funs to melt and destroy its self.

"Hi Steve, from the VW documentation I have the 204 engine was amended in 2019 to fix the cylinder wear issues resulting in the oil issue I’ve had"


++++


note that the turbo charger is not included,




so depending on your miles i would think about having the turbo replaced.

some other members have had the original turbo fail 100-150k miles

@lexhorton 2017 - Turbo?

@Jonp40210 - new turbo?

@bp_porcaro - 2016 204 DSG diagnosed with low compression (17 bar) and oil use about 1 ltr every 1700 miles. Not fixed yet. Quick update on my 2016 204 ...82000 mls. After further work / investigation it appears that the small turbo is / has been the main culprit for my high oil consumption. Observed when the charge cooler was being replaced. Now booked in for new biTurbo unit. Not even thinking about the high bill because it makes me cry

@UVW_T6 - 2017 - new turbo, EGR blanked, DPF removed, mapped to delete DPF, EGR, AdBlue and Stage 1 boost.

@t6stormer - new BI Turbo but still in limp mode ongoing issues

@Deansie - high oil use - snapped shaft on small turbo. possible blocked DPF/CAT.

@Repete - MY18 204hp CXEB, 135000km, Oil weighing done by VW. Outcome is 0,7 liter/1000km.Now anxiously awaiting kulance claim response from VW.

@albiro - 62,000 miles (100,000km), and the oil consumption is measuring at 0.6 litres per 1000km, above VW's threshold of 0.5 litres per 1000km.

@Heydave - 0.4l per 1000km

@RS6plusMTM - 2017 CXEB 65k - small turbo seized solid - replacement turbo and had DPF professional cleaned as a precaution, even though it had no signs of excessive soot. Compression test perfect and no signs of any high oil usage.

@gavbarlow - add mine to the list too. 2017 CXEB, 102k miles. (unsure if turbo or block atm)

@merdoklt - mine had turbo fail at 100k, now at 108k it is consuming 0.4-0.8L of oil per 600mi. Looks like I might have worn out piston rings, etc. Here is a good write up in German about what might be causing the 150kw (edit: 204ps) engines to fail - T6-Motorschaden

@thebuzz555 - I’m at about 1L every 1k, already had consumption test done by VW which it passed, it’ll be getting traded back in to them for a 150 soon

@UVW_T6 -
've also had turbo issues, started squealing and then dropped all power - at only 50K miles (which I think is quite low for turbo failure! :eek:)
204 CXEB MY17(67). Had a new turbo, EGR blanked, DPF removed, mapped to delete DPF, EGR, AdBlue and Stage 1 boost..

@Ashypants -
I think I’m heading the same way…started using about 800ml per 1000miles at moment. Van starting to feel sluggish - got a ‘dead spot’ around 1200rpm. Tried running some injector cleaner through but not sorted dead spot. Think I’ve prob got a few problems going on - high oil usage (engine or turbo) and possibly DMF. Caravelle 2.0 204 BiTDI standard no remap etc. 93500miles.

@t6stormer - new BI Turbo but still in limp mode ongoing issues,
Bought from vanstation (wouldnt buy a wheel barrow from them again) 2017 t6 204bhp 76k miles.within 100 miles limp mode and diagnosed as small turbo snapped shaft, and bits gone into large turbo and damaged that too. turbo removed sent to turbo technics who couldnt do it no parts, however midland turbo repaired it £971. new turbo fitted goes well, however within a week limp mode again, also noticed no boost below 2000rpm. now it looks although its had an adblue delete and this wont allow the limp mode faults to show on vcds or on the van. I've no idea of the history of the van and dont know if its had an egr delete too? so im stuck now trying to diagnose my fault with no error codes. the adblue has 3 lines showing instead of miles, i have filled the tank with 8 liters of add blue but no difference, van still runs but shows no miles
have been advised it could well be deleted. Update on the latest software. Van was taken in and flashed with the latest software, I was hoping on the way home it would go into limp mode and flash up a warning light. However strangely enough it drove home with no problems at all, even had the ad blue showing 6.5k miles. Driven a few miles this afternoon a bit more spirited and still no problems. Im going to keep an eye on this as it did the same after the new turbo, ran well but limp mode after a week. Hopefully now when it does go into limp mode it will show an error code and i can work from there.

@ragnar.sabo - Mine is using more than 0,5 liter pr 1000 km. The turbo faild in july.

@Lolo77 - 2019 T30 204 PS 2.0 TDI bi turbo engine failure. engine failure due to low cylinder compression. Van started running lumpy in low gears, then came the exhaust smoke, immediately stopped driving, P100400 fault on diagnostics, pointing to cylinder 1, replaced but same problem so had recovered to VW approved who has simply said needs a new engine. Aware of the EGR issues and although out of warranty the van has only done 50k miles. Quoted £20k.

@Mart Ini - New twin turbo for me, amongst other very exensive stuff...new inlet manifold with valves cleaned using walnut shells, there was so much carbon build up despite using premium fuel and regualr high revs motorway runs to try and avoid this. There was no high oil useage though, jsut a rattling coming from the turbo, engine light on, no low boost pressure, fine with a few revs through it though but not driveable iuntil it was fixed. 2018 T6 Kombi Highline 204 DSG

@Repete - Another patient joining the high oil use "club". MY18 204hp CXEB. 135000km. Oil weighing done by VW. Outcome is 0,7 liter/1000km.
his week, time had come for my van going in to get the work included in TPI 2061290/6 done. As mentioned earlier we landed the following deal:
VW offering a 80% discount on all parts regarding the TPI. The danish distributor/VW shop agreed to a 50% discount on all work.
The work started Tuesday morning and final stuff finished slightly past midday today (Friday). Had them do the cambelt kit now while at it (139800 km)
So now fitted with
- a new base engine (03N100090AX) (stated as shortblock with cylinder head and all that goes with that)
- fresh Diesel particulate filter
- New Catalytic converter
- New Lambda probe.
- Loads of bolts, gaskets, tubes etc.
The ash level has been reset according to zero as mentioned in early posts of this thread.
Also oil pressure is set to max while running the new engine in.
After getting old engine out they found water in the EGR cooler forcing a replacement of that as well.
Haven´t driven it very long yet but immediately noticed the engine running far smoother with far less vibration.
Looking forward to spin it more to get a sense of more potential improvements.
Good to finally get fix done done and, after bleeding a not exactly small bill, hopefully getting it fully out of my "system".
Massive :) thanks to Dellmassive for creating this very informative thread here.
Has been a great help along the way.


@albiro - 2016 T6 204 CXEB . in the last couple of years the oil consumption has gone pretty high and I just had an oil consumption test done and it's pretty bad news. The van has done 62,000 miles (100,000km), and the oil consumption is measuring at 0.6 litres per 1000km, above VW's threshold of 0.5 litres per 1000km. The VW dealership are recommending a new engine, and they've quoted me £17,800 for parts, labour and VAT. The quote I've got back lists £7871.00 for a "stock base engine (long block)", £1440.00 for a Catalytic converter, £1845.00 for a diesel particulate filter and £295 for a lambda sensor, then there's a further three pages worth of odds and sods like washers, gaskets, bolts, etc. The labour is quote at £2070.00. All the prices then need VAT adding on, on top of that. After a month of going back and forth with VW, they eventually agreed to supply the replacement engine at warranty price, and contributed 30% towards the job. In total the van had a new longblock engine, DPF, catalytic converter and lambda sensor fit at the end of December, coming in at £8,750.00 including labour and VAT. I've put the van up for sale (I don't have sufficient privileges to post on the for sale page on the forum). The overall job original estimate was £17.8k inc VAT, VW agreed to supply the parts at warranty price rather than retail which brought the job cost down to around ~£12k, and VW contributed 30% (so ~£3k) and I paid £8.7k.

@Martymuffin - What, so 1Ltr of oil after 1,500 miles is not good…Yup, I am another one. 204 DSG (2018) 4 motion 60k.

@Heydave - I think I’m also a casualty. Sportline 67 plate owned from new, currently on 37500 miles so .mainly local stop start. Noticed oil level dropped by around 0.3 l topped up reported to dealer car case seal was changed but made no difference to the oil consumption loss rate. Coil light came on and went intolimp mode. Dealer said not egr but flushed it out anyway. Started to worry after reading about the CXE engines on the forum. I’ve tried 2x 600 mile tests and used around 0.4 l each time. Although this passes I’ve booked in for a consumption test anyway as I fear that it’s the beginning of the end. My all in warranty runs out in February next year! Other issues I have noticed is a slight rattle from the engine when feathering the accelerator and sometimes a slight juddering as though it running out of fuel in low revs, and although it’s a dsg the engine has stalled twice. Not sure whether these symptoms are all related in some way. Furthermore I have had long life 2 year service plan but now concerned it’s should of had a fixed term service plan(every year) due to low mileage/ stop start

@RS6plusMTM - 2017 CXEB 65k - small turbo seized solid - replacement turbo and had DPF professional cleaned as a precaution, even though it had no signs of excessive soot. Compression test perfect and no signs of any high oil usage. Pretty sure it related to poor oil heat management of the CXEB as for me it failed after a 500+ mile, all day drive in the 40 degree French heatwave during this summer and it seized leaving it to cool over night. A month for the AA to repatriate the van back to the UK and then a further 3 months waiting for the turbo to come into stock from being on back order so only just got it back this week.

@gavbarlow - . 2017 CXEB, 102k miles.. This discussion has been very useful and has helped me to diagnose some issues with my 2017 204. It's just done 102k miles, and has been religiously serviced by VW since new. It's used daily as the work van and regularly does mixed journeys and have experienced not issues with it at all in that time. Just recently its started displaying an engine light which registered as a glow plug 2 fault and EGR flow fault. When re-setting the light, the EGR code wouldn't always come back, but figured I needed to look into it further. Over the festive break I took the opportunity to replace all four glow plugs and whipped out the EGR valve and associated pipework. The pipes had been replaced under warranty around 4 years ago as one had split causing a blowing exhaust noise, so I was hoping they would be in good order - I was wrong! The front pipe from the EGR to the inlet was nearly clogged with an oily carbon buildup that resembles toothpaste. I've now got a new EGR valve and associated fittings ready to go back on, and the bill for genuine spares alone is around £800. Having read this feed (and all the others on the topic of turbos) I've taken the decision to remove the DPF and bi-turbo while the EGR was out as it's slowly started to use more and more oil. The inlet pipes to the turbo had oil inside all of the them, the exhaust manifold was full of oily/carbon deposits, and the gasket was saturated in oil. The lower spindle has some considerable play and the top spindle feels sticky and not free spinning as it should be. A rebuilt turbo, fitting kit and a DPF clean at Darkside developments will set me back a further £1500. Yes, the job is as bad as it looks/sounds - the VAG repair instructions give you a good steer but it's not quite as straight forward to do having never done one before. I'm an experienced mechanic and restore historic vehicles for a living so I know my way around an engine bay. Even so, I found this one of the worst jobs I've done in years given the limited access and poor visibility.

@Manu - T6 (2017 204 biTDI, DSG, 4m, 60k miles) started to consume more oil than it used to. Until now I only had to add 0.5 to 1l of oil between services.... On the last long trip (around 2k miles of European motorways), it went through something like 3 litres in 2k miles!. Also got the 1000km/650 miles Adblue warning popping up despite adblue tank being full (3 times...). The warning would clear on its own after a few miles but gave a 31103 code SCR/NOX error.

@WoopsBoughtT6 - 2017. 71000 miles. CXEB engine. Burning about 0.5ltr / 1100 miles. Will be doing an oil consumption test over the next 600 mile round trip journey as I think it's drinking oil when on longer trips.

other 204ps members unaffected: AKA THE LUCKY LIST

this could be due to the 2019 revisions? - (possibly the 2016-2019 range as there is a mention that the CXEB Block/Pistons etc was revised in 2019)

@Bigsidavies 2017 CXEB 204 - (135k miles so far) (EGR delete, + EGR Delete Map @ xxx miles)
@VanDamMan
@BoroBoy
@catfood12 - 2017 CXEB, 50K miles. Oil changes every 8-10k. Revo remap. Lots of mechanical sympathy, gentle warm up and turbo cool down
@True Romance - 2017 CXEB. Just about to hit 30k miles. Oil change every year. Consumption very low. Only do about 5k per year but nearly all long runs.
@Deleted Member - Mine is good. 155K miles. From new it was a corporate London airport transfer vehicle out of Norfolk, so always did long journeys. As the second owner from 129K miles in March 2021 I've kept up the FSH and never ever ever use it for short journeys. It had a new DMF at 133K miles. Miller oil check August 2022, all normal. I had the EGR physically blanked and mapped out 6-12 months (a few thousand miles) ago as a preventative and because the engine monitoring app I was using was seeing occasional sticking. DPF looks fine last time I checked.

@ALFIrE - 2018 204ps biturbo. 70k miles. no oil usage. remapped 255ps 530nm torque. now booked ar dealer for excessive coolant usage (1l / 1000km). minor leakage water pump, major leakage EGR cooler. will be replacing timing belt during same surgery.

@Cheetham - I have a CXEB engine in my 2019 transporter, it's a sportline panel van, driven 90% of the time on the motorway, full VW service history and I have 160k miles on the clock. Had the egr delete done and now it runs smoother. Only thing I had go wrong is the inlet manifold swirl flaps needed replacing at 140k.
So the revision in 2019 to the CXEB engine has worked.

I’m currently running a 204, 112k miles with oil consumption sat at around 1L for every 2000 miles. Monitoring very closely.

Frequent regen’s at 50 miles urban, 120ish motorway and 75ish if mixed.

Adblue and EGR mapped out but not blocked as it was coded out weeks after a new EGR was fitted, so Iv took a risk that the valve remains shut.

I am keeping my fingers crossed that mine is impending turbo failure due a high pitched wine under load (between 1500rpm & 2000rmp). I also have a confirmed fault code, inlet manifold runner position. It’s not looking good but I am keeping my fingers crossed it’s the lesser of two evils. Due a belt and pump in November so I’m hoping it’ll last until then and I can get it all done in one hit. I certainly don’t have 12k lying about for a new block!
