[Solved] 06 Jetta - Disconnected battery, now VCDS can't find ECU
Hello folks.
My 06 Jetta TDI has been having problems with discharging the battery overnight. I was thinking it was the battery going bad so I charged it, then pulled it out and took it to AutoZone. They told me that the battery was ok. I put it back in the car. Now when I turn the ignition on, I am getting the flashing PRNDS and the car won't start.
I cleaned up the ground connections and tried again - no change.
I can scan all of the modules in the car with VCDS, except the engine. Some of the modules complain of missing ECU communication.
I am leaning towards a bad ECU.
I am trying to pull the ECU to re-seat the connector and try again.
What else should I do?
What will it take to replace the ECU?
Thanks.
