Now I got a new code: Heat Exchanger Right N/A.
Not the sensor this time.
Is it two in my BMW and what is the best way to change it?
Searched the internet and youtube but can`t find it.
Excuse my problems ;-(
Your problems seem weird. If I had to guess, you have a connection or broken wire issue somewhere.
Also, you haven't told us the conclusion with the sensor. Did you replace it with the one autodoc told you? It would also help if you shared your VIN with us and the exact part numbers you used on your car.
