I agree with the previous post, 12.5 is too low while the engine is running. It should be around 14. A low voltage issue on such complicated electronics like the ones fitted to an SL may cause all the problems you describe.

Also, just for fun, I would check the engine wiring harness issue on your M104 engine. I KNOW, I KNOW that this particular problem was solved by 1996, but U.S. production models tend to sit idle in Germany for a while before being shipped. So your car might be one of the very last models fitted with faulty wiring harness (which may also cause all the symptoms you describe).
