- 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:

VW T6 204 Bi-Turbo - Engine replacement - £12k-17k What are my options?

Hi all, Apologies such a long one on my 1st post but was hoping someone could offer some advise re an engine replacement for my 2017 T6 204 DSG Sportline. (CXEB Engine) Always dreamed of a camper and I bought the van privately just over 12 months ago with 100k on the clock, and obviously I...

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 all Im new to the transporter game, I have had this issue also on my 67 plate sportline I bought back in January. It failed the consumption test last week ( managed 140 miles before the oil light came on ) and have been told it’s a new engine job. I luckily have a couple of weeks warranty...

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

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.

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!

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
