Hi

I had some problem with my ECU, and got another used one. The used ECU had the same serial number and everything. When I put it in my car, the car starts, but turns off on its own in about 2 seconds.

What am I supposed to do to get the car running??

oh btw, this is an 03 passat, v6.

Any help appreciated.

thx

i think the 03's have immobilizer which means that the ecu is specific to each car. the dealer can reprogram the ecu to work with your car, i believe. maybe someone with an 03 can spread more light on this.

Thx, Dr.passat and everyone else.

I printed out the procedure for immobilizer III and gave it to the mechanic whos working on my car. He has the VAG COM tool.

Now he says that he cannot communicate with the computer for the instrument panel. He says he needs one of the numbers from there, but cant communicate.

Any suggestions??
