Hi my E320 cdi is playing up a bit. Groaning noise coming from engine bay when stationary in traffic, doesn't cause any probs just annoying, sounds like something is running as well as the engine for a few seconds, if you get my drift. Front and rear parking sensors working visually via lights , but no bleeping, and display says front o/s parking light out, but it isn't, and wing mirror indicator, again o/s a bit intermittent when in use. Any help appreciated.
Cheers Richard
