Hi,
I have a problem with my Mercedes-Benz SL600 1996. I have fiddled with the carsoft diagnostic software. I may have pressed read/write ECU data something something....
So now my engine check light is flashing. The fault code is P0450, witch is faulty fuel pressure sensor. I had the car to my local mercedes dealer, and they said that this sensor is not fitted on my car. It is only fitted on cars sold in certain countries.
They had no clue what to do.
I guess I activated some sort of function that was turned of when I fucked the whole thing up.
The only thing that does not work is the cruise control. The engine starts and runs fine.
Anyone have any idea what i can do? Should a tuner company easily figure this out?
I think the ECU is a Bosch ME2.7
