I am slowly getting more familiar with this problem the more I read about the other ASR problems posted. It looks like I am definetly going in the limp mode. I found out the ASR & ABS lights do not work when in the limp mode or when the ignition is first turned on. I do get the ASR function lamp in the center of the spedo on when the ignition is first turned on, then it goes out after starting the car. I also have the "Snow Chains" switch lamp working.

Is there any way to check the ASR & ABS lamps without removing the instrument panel?
If a faulty diode in the A7k1 relay can cause the ABS not to come on, can it also cause the ASR lamp to not come on? (the wiring diagrams show 2 diodes in one drawing and none in another drawing)
What is the purpose of te R25 "safety switch". ( I have the high resistance across the contacts)

I built the LED test lamp and it works great. It looks like I may have a TN problem. I cleared the codes and will drive again and recheck the codes tonight.
