MK5 GTI - Dead ECU

[harley1990]

Success! Went into VW this morning, got a call this afternoon that my second hand ECU had coded fine. They couldn't really tell me what they did/the process, but was $165.

So:
Initial diagnosis/testing: $200
ECU: $350
Tow: $80
Coding: $165

Total: $795. Not the cheapest exercise, but still better than $3k. Now to try work out how the drainage works and how it got so much water in there.

I am calling that a bargain.

do yourself a BIG favour and replace temp sensor as these fail and allow coolant tp capillarize up the wiring harness into the ECU. If you have coolant in the ecu[taste test] you will also need to replace the wiring harness in the engine bay...done a few like this recently. cheers steve

^ Yep.

Beetles and Golf 4s would do it into the dash cluster via the level sensor in the expansion bottle.

Yep, still a good result.

Had them both replaced a little while ago (12 months or so) after something else was throwing up incorrect fault codes. It's definitely water in the old ECU (happened straight after it was washed).

Yes you got a bargain there - nice work. Now I'm going to grill the guys up the road and tell them to pull their finger out
