engine management fault 2.0 tdi passat
Discussion
hi there
after a bit of advice on a problems my dads having with his car
basically my dad bought an 05 plate passat 2.0 tdi sport 2 months ago. after a month the engine management light would come on and the car wouldnt start so he took it to dealers who diagnosed it as a faulty injector and had a new injector fitted. now when driving it there will be loss of power and the engine management light would come on. if you stop and start the engine again it goes back to normal. now the dealer wasa saying that the ecu needed replacing at a cost of £900 but when he sent it to a company that reconditions them it came back as being perfectly fine.
i came across the thread below on another forum where the person had the exact same problem which was solved by an update. now when he rang the dealers they said according to the records its had the update. now what i was wondering does antone know if theres a way to check if its been updated and is there a chance that it didnt install properly the first time?
thanks

Was it the main VW dealers? or just a car sales dealer.
Is very unusuall for an 2.0TDI A4/Passat to need an engine ECU. But it is posible. I would tend to believe the VAG main dealers, they have the best equipment + all the relevant update and technical solutions information, that other garages wont have.
But there are a number of different causes for the symptom he is having. (The car going into limp home). Leaking boost pipes or intercooler, fault turbo or boost pressure sensor, even broken vacuum pipes etc.
Regarding how to tell if the car has had an update.
As soon as the main dealer checks the fault memory it will also reveal the software level of the ECU (normally four numbers), this will tell them imediactly if an update has been done or not. With the paperwork that is published with the updates if and when they come out, it will show the before and after software levels of the ECU, if the ECU is showing the after number then it has deffinatly been done. For example 6651 may become 8087. The newer version is always a higher number.

I understand not wanting to spend £900 and still have the fault. As I said I would tend to trust the main dealer, but having said that, from the information you have given me, I have to say I dont thinks its going to be an ECU.
But they have seen and tested the car I havnt. If I had a bit more information I could give you my reccomendation.
DO you know if there are any faults stored in the memory? and what they are.
Most importantly, Did the dealer explain why they think its the ECU?
