You can get oem from Germany there not so cheap about £600 or you can get 1 from China on eBay for around £150 with the gaskets Chinese turbos are upgraded a lot and make the car very quick when remapped ( I have 1.8t20v Passat with 1 on. Higher boost pressure more strain on engine I wouldn’t go above 10-15 percent. Make sure you feed oil into the turbo prior to fitting or you will damage it when it runs dry for a few seconds till oil reaches it. I’d also make sure you change the inter cooler so your old doesn’t contaminate new turbo and prevent veins from operating properly. Hope this helps mate

Can anyone advise me what is likely happening and causing this problem? grateful thanks...
The dashboard Engine Protection Light comes on when Engine goes into limp mode
I think you have just answered your own question you need to get it checked with vagcom for codes before you try anything
Best answer (according to Rambo)
It’s a diesel could be many issues could be injectors could be egr valve all chocked up ( most likely fault ) could also be cam or crank sensor bad maf sensor is stronglt recomend use of good diagnostic equipment. To save lots of time and point you in the right direction. Could also be fuel pressure regulator. Just looked back it’s a 2008 it’s more likely to be dpf filter. And or egr valve hope this helps
I've been told by two garages that it's tge Turbo Pump exhaust fan which is the problem and that the Turbo needs to be replaced. They sounded quite convincing.
CommentFailure when speeding up Solved
Volkswagen Passat 2008 114000 miles
I have a Passat 2.0 turbo 2008 and the other day, when speeding up to overtake a car, the car failed. I then reduced the speed and went on driving properly. But every time I went over 60 mph, the same failure appeared. I would appreciate your help.

The problem has been solved. It were coils numbers 2 and 4 that were damaged, they were replaced and the problem disappeared. Hope my experience can help someone.

CommentEmergency mode
Volkswagen Passat 2004 3BG 1.9TDI 223693 miles
Automatic gearbox, whenever you give it too much gas when it wants to shift, it enables emergency mode, and limps. Only way to “fix” it, is to restart the engine. Bought new gearboxes, turbos, injectors and nothing works. Ecu also doesnt show any errors.

No power 1.8T
Volkswagen Passat 2002 1.8T 165906 miles
The car has no power, sometimes it runs great and sometimes it doesn't and sometimes it starts to run really well up to over 4000rpm and it seems to jerk... what's new: vacuum hoses, maf sensor, turbo, fuel pressure regulator, n75, lambda before the catalytic converter, fuel filter, spark plugs... I've been dealing with this for a year and I can't figure anything out
