Hello everyone, I have a very big dilemma. I have a 2002 TDI Jetta with around 270k miles on it. The other day I noticed the A/C was blowing hot at idle, checked it out replaced the main cooling fan. That problem solved fans working correctly. The next day I am assuming just coincidence, car goes into limp mode. I pulled the battery cleaned all the connections removed and sanded the ground for the battery cable, the ground next to it, removed and sanded the ground next to the computer, and pulled the computer and sprayed it with contact cleaner.
The next day the car ran fantastic no codes put about 50 miles on it. Day 3 same issue on the way to work. Here are my questions
1. How often do the computers malfunction?
2. can the 109 relay be an issue even though the engine runs and starts every time?
3.Does the check engine light with no flashing glow plug light still mean "normal" limp mode
Here are the codes in limp mode with VCDS
19561 16629 17964 17849 16600 all open or short to ground. I have a hard time believing all this could happen simultaneously overnight. Also the car will kick out of limp mode some time after a few miles of driving at 25mph and back to normal for ? amount of time.
Thanks in advance for any help I drive 80 miles round trip every day to work I can't afford to not have this car running
