Looks like I’m getting recovery T6 is dead

[GavMc P11GT]

Hope someone can shed a bit of light on this. Been out in the van all day no issues however it’s just shit it’s self literally.

Travelling down hill accelerating down the dual carriageway and it sounded like it had farted there was a small puff of smoke.

Initially lost power but no lights came up.

I limped it into a safe spot and popped the bonnet. And there’s black soot all over the front of the engine block, back of radiator front of gearbox and all of the hoses etc.

Now have the flashing glow plug light and start stop fault and no power at all

If I rev it sounds rough and the revs tremble even when I hold it steady.

We have VCDS at home but need to get it there hoping to get it hooked up asap but any one had anything similar?

Sounds like a boost pipe has blown off, have you had any work done recently? I would of expected a EML as soon as it blew off though.

 

[GavMc P11GT]

Nothing tbh it’s been behaving its self up until now need to find a picture of a CXGB engine and showing all of the front hoses etc so I know what I’m looking for.

Egr pipe split ?

 

[Ruby16]

Is the lower intercooler pipe firmly home, they can blow out if accelerator is hit really hard, or if the small retaining ears have become corroded?

Egr pipe split ?

The front one feels like it has a very slight leak at each end.

Will check tomorrow it’s at my parents house for the night.

 

[GavMc P11GT]

Managed to get it scanned these have shown up

I’ve had another look this morning got no tools hand where it’s at hoping to get it home today or tomorrow the amount of soot down the front of the block is ridiculous I shit you not everything has a thick cover of soot, block, pipes harnesses the lot nothing on the top of anything looks like there’s a small puff of smoke coming from the back corner of the engine bay drivers side too.

It’s gonna be expensive Mrs Bird will be feeling it in her knees (Paddington for those who don’t know)

Hi guys having a bit of trouble with this code P010100 Cleared it gave it 50km test drive came back on with the EGR low flow code. Checked my voltages to Maff sensor and pressure tested boost system can’t see no leaks at intercooler. Could do with a hand if someone knew correct voltage at maff...

Cheers for getting back to me! I’ve been knee deep in google all morning looking at diagrams of the engine and i hadn’t realised the the inlet manifold was so low on these can confirm that the intake manifold is completely covered in soot and it’s like everything surrounding it has soot on it but given its location I’m thinking that’s the culprit.

The van has just over 110k on it so would imagine that will have its fair share of carbon inside of it I can’t feel any air blowing from it I’m gonna get a smoke test on it to find out 100%

Are the intake manifolds common on these? It’s been regenerating lately but when scanning the soot levels on the dpf they don’t seem all that bad.

I notice the manifold is plastic (never been a fan of plastic manifolds to be fair)

Engine running at standstill there is not much pressure to blow out (not even by revving the engine), actually could be even a slight vacuum.

Yes.

Soot level doesn't relate to manifold pressure, or turbo pressure.

 

[GavMc P11GT]

Dealer part only by any chance?

 

[Dellmassive]

Deffo sounds like somethings has popped in the inlet side.

You have air filter to turbo.

Then turbo pipe to charge cooler,...

Then charge cooler to inlet manifold.


So as above any of the pipes, charger cooler or I left manifold, which is plastic.... And a known failure point.

Possibly caused by a blocked DPF causing excessive back pressure.

@mmi is a master at reading vcds data... And that shows no pressure.

The black soot is normal for a diesel engine, but is always filtered out through the exhaust system.

....


I've had very similar to this year's ago on a 530D BMW we had.... The turbo boost hose split at the inlet to the charge cooler..... I tried a temp repair using a bike inner tube and a few jubilee clips around the split.

But that didn't work and blew straight off..... But. What I did notice was the distinct turbo woosh sound that you haven't mentioned above.

So maybe your leak is smaller..... Ie hole in the plastic inlet manifold?

 

[Dellmassive]

Al's start posting pics, loads of them.

And even a video clip if you can... Drop a link here to the video clip.

Of it starting and ticking over and a throttle blip..... If you can.

 

[GavMc P11GT]

Latest scan I’ve got it home now.

I’ll upload a video as soon as I work out how

 

[GavMc P11GT]

I’ll have to do another video this one has no sound this weekend can swivel for me nothing working at the minute.

 

[Dellmassive]

upload to youtube, then drop a link here.

or

drop a link to a shared file on your Apple/Google photo app.

oxygen sensor - heater circuit open

turbo actualtor - for the variable vain, specified 30% actual 0%

and

turbo compressor outlet - 0mbar and 0%

+++++++++


so the engine computer is picking up charge presure faults.

@mmi we know theere is a physical fault as the black soot is evident in the engine bay,

so we know the outlet or inlet path is split somewhere.

not sure if a block map data download will give us enough data to locate where the leak is - just from data dump? - what you think?

 

[mmi]

Latest scan I’ve got it home now.

Would be easier to keep track of the things if you could just copy and paste the scans as plain text.

oxygen sensor - heater circuit open

Different fault code in the second scan. And in both scans the faults were still "only" at status "Not confirmed".

turbo compressor outlet - 0mbar and 0%

I think these (two last lines) are just placeholders for bi-turbo engines, thus not an issue here.

not sure if a block map data download will give us enough data to locate where the leak is - just from data dump? - what you think?

The blockmap data is always useful - as it's complete snapshot of every sensor and actuator status in the engine. E.g. the turbo actuator is at it's low and high limits in the two cases below. E.g. as >>> here <<<

@GavMc P11GT Please post

(1) - engine's blockmap data - engine not running (ignition on)​

(2) - engine's blockmap data - engine ticking over (idling 830 RPM)​

VCDS > Applications > Controller Channel Map > ​

Tick/fill boxes as above and click Go.

VCDS flashes screens for a moment (when finished hit "Done, Go Back") and there should be two files - blockmap-01-... in folder C:\Ross-Tech\VCDS\Logs\....

PS. For the above either VCDS HEX-V2 or HEX-NET cable is needed.
