BiTDi failure [Resolved]

[Crazymind]

Forever doesn’t go along with anything turbo diesel built after Euro 6. And engines are not anymore built to last but built to pass emission tests.

Hi all, my 2018 DSG bi turbos low boost turbo has failed at just 31,000 miles!
The van has been well serviced with regular oil changes.
The engine management light came on and my local garage said it was probably just a sensor that was faulty so I carried on driving the van for a week while I was waiting for it to go in for inspection.
Driving on the motorway the van went into limp mode.
My garage said the DPF was blocked and they wouldn’t do any more work on it until I had the DPF cleaned so I took it to a DPF cleaning specialist garage and had it cleaned.
The van was still in limp mode after the DPF clean.
I took the van back to my local garage and they inspected it further and have said the low turbo isn’t producing boost but the main turbo is ok.
Is it possible to replace just the low turbo or do I have to replace the entire turbo?
Should I buy a new one or is it safe to buy a reconditioned one as I don’t have £3,000 for a new one!!
Even though most of my driving is around town surely a turbo shouldn’t fail at such low mileage?
Any advice would be greatly appreciated.

Well it turned out that my low boost propeller shaft had snapped in half and luckily none of the propellers fins had broken off and entered my engine.
A great mechanic called Serge who owns VAS Technical in Ashtead near Leatherhead, a VAG specialist took my engine apart.
He had to remove a lot of my engine to get the the turbo.
Serge said the high boost turbo was fine and so replaced the parts on the low boost and put it all back together.
All worked well, and much cheaper than a VW main dealer but then the light engine warning light came on again and this time the EGR valve had failed which was another 5.5 hours labour and £600 for the EGR valve.
Finally back on the road and all is good still

Are you sure the failed turbocharger didn’t dump oil into the DPF?
What was the state of the DPF prior to the turbocharger failure? It’s becoming apparent that a clogged DPF (constant unsuccessful re-gen’s) is creating back pressure and causing turbocharger failure on the CXEB 204PS BiTurbo.

When I had the DPF cleaned by a specialist he showed me the reading and it wasn’t that bad. It could well have been the cause of it though.
My DPF light came on briefly then went off again so I was none the wiser.
The van gets driven down the motorway but probably not enough.
Why wouldn’t the DPF light stay on if it’s getting more blocked?
It’s a load of bollocks if you ask me for a £50,000 van with very low mileage and an oil change yearly with fully synthetic oil.
