Hi fellas.

I looked, and am pretty sure it's out there, but I can't find a thread on it... so if someone wouldn't mind telling me where i would find the ECU on my 03 TDi wagon, I would be much appreciative!

I am getting immobilizer issues, and thought the time would be good for a reflash with immobilizer delete and a little more go.

Thanks in advance!

Under the cover at the base of the windshield.
It's necessary to remove the wiper arms, and the small plastic trim pieces in the fenders near the hood hinges before lifting the cowl cover up.

And when you get there you will find that the ECU is held in by two small strips of metal that have been pried up so the ECU won't jump out. You need to carefully flatten these out. Then I use open end wrenches on the pin lugs to wiggle it out of the track it is in.

Since you are taking it out I am a RocketChip fan and if you email him and mention my name he will respond immediately. Send me a PM and I will give you my real name.
