Hi All, I've been having a few issues with my recently purchased 2010 e350 coupe OM642.83 (93k miles). No codes showing. 1) The car struggles to start on first cold start but then remains fine for the rest of the day. Glow plug lights go off straight away as they should, and both plugs and...

So I foolishly snapped the plastic connector while swapping thermostat and had to get a new one of these (£90!), the old one is sandwiched on the right side underneath some injector lines and the rail.

Hi all, I'm sometimes noticing that the radiator cooling fan is running at the end of a run when I wouldn't expect it. I don't know whether it's running throughout - I just notice it as I slow enough to hear/notice it. This has been on perfectly normal warm-ish days (16-18 degrees C) with...
