Had flat bed pick up car today, went to a private mercedes mechanic, once again engine ran for about 15 minutes and stopped. no sign of starting. he said if it was cps crank sensor it would still sound like it wanted to start. he immediately put in another CPU RCM or what mercedes calls K-40 and car continued to run over 40 minutes. will pick up in a couple of hours and drive home for the real test. he assured me it is fixed. I mentioned the possible poor solder joints, he felt it was the fuel relay causing problem. replace whole unit and be done with it part was $200.00 his cost from mercedes. No cost to me as I had taken out a 5 year 75000 mile extended warranty. Whew! sure glad I did!
