    Hi All,

    My E220 is currently having intermittent cold starting issues.

    It'll often turn over repeatedly for ten seconds or more before I give up and try again, ...and sometimes again, before it roars into life.

    For what it's worth, it kicks over as soon as I turn the key for a warm start, but this is getting to be very rare for a cold start.

    After reading up a bit, I replaced both the OVP and the fuel pump relay in the past week. No difference! Also in the past couple of months, there has been a new battery installed, new spark plugs, new fuel filter & pump (I think).

    Tonight I removed the inlet hose and gave the inside of the throttle body and butterfly a good wipe with brake cleaner. It was pretty filthy! The car started immediately after this, but I don't know if it isn't playing with me now... :confused: I'll be more confident after I've had five consecutive good cold starts under my belt!

    If anybody has any suggestions of anything I should follow up on, I'd be grateful to hear them.

    As of this morning I was still plagued by cold start problems.

    I dropped in to visit a couple of aircraft engineer friends who helped clean the throttle body a lot more liberally than I would've done, me not knowing how far to go with this sort of thing.

    I'm now waiting patiently for my next cold start opportunity.
