I have problems with the turbo of my Passat 2002 TDI Sometimes it stops working other times it works perfectly. What factors affect the turbo performance. Is the oil type, or coolant a factor?
Re: I have problems with the turbo of my Passat 2002 TDI...
The wastegate controls the operation of the turbo, it directs exhaust pressure to the turbo, If it does not function properly the turbo will act erratically

It may have seized up turbo bearings, when they get hot they expand and the turbo blades will not turn. Pull the hose and try to move them, if there is any resistance then that is likely the problem and you will need a new turbocharger installed. Don't replace it until a qualified tech has confirmed that turbo is the problem.
It will affect the car if it is burnt oil or you dont keep an eye on consumption and run low which will burn up turbo. I would suggest visiting www.tdiclub.com and reference your model there. The site is FULL of TDI experts and even lets you see if anyone is in your area. A lot of people like to work with these engines (TDI) and they have a big fan club. You might find a DIY person in your area that will help you pinpoint the problem better and help fix it at a much lower rate than a dealer. Remember OIL is the life blood of your car!
Hallo 1.Disconect lower hose from intercooler and oil (from 0,1 liter or more) (sometimes 1-2 liters) comes out, you should not drive it.(car had probably loose power) Change the turbine, oil and oil filter. do not forget to disconect lower hose and let oil drain out. Otherwise when new turbine is instald, the air flow will **** this oil inside the engine and distroy it. 2.your car is not designed to run without turbine and will not work like normal disel.(SDI). hope it helps Marko
the car is going into limp mode due to an engine management fault. have to check what the fault is with a code reader. if the milage is high 100,000+ could be a turbo fault (overboosting), as this will put the car into limp mode.
have you checked your air intake system? A clogged air filter will severly limit the amount of air that it can get, or a leak in the exhaust driving the turbo will limit the amount of pressure to spin it. Start by putting a new filter on it. Then if that makes no difference, you can check the waste system by installing a boost gauge, so as to check how much pressure you're actually getting to the manifold. If boost is normal, then you need to look for fuel system or mechanical factors.
Check the mass airflow sensor, this is quite a common fault as they easily get contaminated with oil. This damages the delicate element inside.
It is mounted between the air filter box and the hose down to the turbo, it is held in by torx headed bolts and has a multi plug that needs to be disconnected.
Cleaning it with spray brake cleaner may work if not it needs to be replaced.
