Hi I drove my 1999 E-CLASS Saloon (W210) E 280 Petrol (12/96 - 03/02) for about 40 minutes stopping once and all was fine. Once I got home I went to restart the car after about an hour and it started but then stopped within a few seconds. The engine actually ran but only briefly. I tried a number of time with the same result. After a further couple of hours I tried again and the car started and ran first time and I drove it without issue for about 20 miles. No engine warning lights lit up. I have had two previous Mercedes (C180 and a C200) and both had a faulty crankshaft sensors with similar intermittent issues but I don't think they started to run, just cranked. Does this sound like the crankshaft sensor? If not what else can I check? I thought at first it was a fuel problem but once it started it ran fine. Many thanks in advance.
