Motor CXG turbo damage?

Hello everyone!

Unfortunately, I'm not up-to-date on the latest technical developments. Current status.
Since I've been working a different job for 10 years, and I only work on cars now for my own use / a few friends / family.

Now it's my company car that's been affected.
It's a VW T6.
Motor CXG. Approximately 2016 model. 86,000 km.
1.9 TDI, I think it's 74 kW. The car also had AdBlue and a piece of software designed to cheat emissions tests.

The car is driven 95% of the time by me, and I take very good care of it.
My typical driving pattern is 50% highway driving, and I usually drive around 120 km/h (approximately 75 mph) on the highway.
Remaining distance: country roads and city traffic.

On Wednesday, it happened, suddenly and without any warning:
I'm driving in the city, stopped at a traffic light, and suddenly the engine power is very low.
For that, I can hear the sound of the turbocharger releasing pressure.
I thought to myself, "No problem, I'll just pull over to the next parking lot and take a look."

I saw an intercooler hose that had slipped down slightly from its connection, but it wasn't completely detached. I brought my tools with me, so I properly reattached the hose.
It didn't help, though.

So, I carefully drove along country roads to the appropriate VW workshop. Then the heating element started to flicker, and later on, the yellow engine warning light came on as well.
It could be a leased car, or it might have a maintenance contract.

In the workshop, there was also a Corona car, and it looked like it was almost bankrupt (no one there, no lights on, no cars in the yard).

I then looked for the boss (who was the only one there).
We didn't find any leaks.

I left the car there and picked it up today.
The boss told me that the adjustment on the turbocharger is fixed, and a new turbocharger needs to be installed.
That won't happen this year, because they are currently not available.

Great.

I'm somehow not comfortable with the whole thing.

Do you know if that's a VTG turbo?
Where is the air supposed to be released?
I can hear it clearly, but unfortunately, only while driving.
It's not reproducible in a controlled setting.

Actually, it doesn't really matter to me, I just have some concerns.
that it might become too expensive, and the car might not be repaired.

I'll either end up with some Ford Transit van, or that old, rusty, and filthy vehicle that our former janitor used to drive, now that he's retired.

I don't like either option.

Taking my nice company car home sometimes, and occasionally checking things out underneath it in my pit.
it might be more than just a minor issue.
That might be possible.

The questions would be:

Does that sound plausible with a broken turbo?
Does it have a VTG turbocharger?
Is the error known?

Hi Steffen,

Are you sure the engine isn't the 2.0 TDI with code CXGB?

He has a VTG.
Okay, I'm ready. Please provide the German text you want me to translate.

Since I've read about T6 turbos being damaged by ice on several occasions, I installed a heating pipe insulation for the oil filler neck and various hoses on my CXHA.
It is known that condensation can form in the intake system or the intercooler, which can damage the impeller of the turbocharger compressor.
Another advantage is that there will be no more water-oil mixture accumulating at the filling opening.

After 140,000 km, I haven't been able to detect any functional problems with my turbocharger.

You might also have a problem with the exhaust gas recirculation pipes, which are difficult to access, especially at the rear of the engine.
Okay, I understand. Please provide the German text you want me to translate into English. I will only provide the translation.

Best regards, Rainer.

Hello!

Okay, so CXG is correct.
I took a picture of the sticker on the timing belt cover.
I was also a bit surprised because the newer ones all have four digits.
but it's really clearly CXG.
There's no "B" scratched out or anything like that.
That would create too large a gap.

Hi,
The sticker on the cover reads "CXG <engine>".
"Just like it says on my Horch CJC, with the engine number <engine>." It is still a CJCD. The three letters represent the engine configuration, and the fourth letter indicates the power available via STG.

Hi!

Thank you for the information.

Then we have it.
According to Rainer's table, it would then be a CXGB.
with its 75 kW.
Then everything fits together.

I am familiar with how the VTG works.
I successfully cleaned that on my Golf once, when it was still fixed.

With my Golf, I didn't notice much, except that it would go into limp mode under load at exactly 3000 RPM. I would have to stop, restart the engine, and then it would work again. Without anyone making a sound.

And this company van is 20 years younger.
and releases air with a clearly audible sound, somewhere.

Hi,
If it whistles, there's a hole. I would check the charge air hoses, even by feeling them with my fingers (squeezing them).
What does the error memory say?

Hello!

Okay, I unexpectedly got my car back today.

So, it wasn't the turbo...

The workshop manager told me that...
Apparently, some stainless steel pipe, which is related to the EGR system, had broken.
The flange broke off.

I haven't seen it myself, though.
You don't see much from above; it's quite built up.
And I can't see from down there...
To do that, I would have to take the car home with me.
We usually shouldn't do that.

Standard error, corrugated pipe made of the thinnest sheet metal that vibrates.
