    E63 5.5TT - light throttle surging

    Hi there, I've noticed that my 5.5TT has a mild to moderate tendancy to surging when on a constant throttle between about 1600 - 1800rpm. It makes the car feel jerkier and less refined than I'd like. I also noticed that on at least one occasion swapping from Shell to Tesco Momentum made...

    Surging and miss firing after MOT.

    My E350 was in for its MOT on Tuesday, which it passed. Since then though it's been surging and miss firing particularly when the engine is cold. I realise it could be a coincidence, but is there anything that the MOT could have done to cause this sort of issue? As prior to the test it was fine.

    Air con "surging" on W124

    He air is being used now that it's warm. It blows cold well enough but it seems to be making a sort of whistling "surging noise" .... It does it about every five seconds. Any experience here on the forum or am I on new ground with an original fault? Thanks in advance.

    W202 c200 power surging

    I have just acquired a 1997 c200 manual and have a slight issue with it. It starts and runs fine in general but the power surges on and off throughout the rev range. Will pull too the limiter but throughout the revs the power delivery kinda feels on-off-on-off. Any ideas what it could be? Car...

    Slight surging at idle in gear, S124/M111

    My S124 is suffering from an intermittent surging at idle when in D/3/2/R; sometimes it'll settle nicely on 750rpm, other times it'll pump from 500 to 1200 and back, or higher if I put the shifter in N/P. When it's surging, sometimes revving past 3k will fix it, other times it'll keep doing it...

    surging engine

    My Cdi seems to have developed the art of "surging" where on 2 occasions it has momentarily had a "power surge" making the car "jump". It seems to do it when cold. It does this only when cold. Co-incidentally the gearbox oil was changed on saturday but I doubt this would be to do with it.

    Surging Engine

    My 1995 C200 pulls unevenly especially when accelerating. It seems to accelerate well enough but the rate of acceleration slows down and then picks up, almost as if it is getting choked and then clears. It's not particularly prominent but its there. You can even see the tacho hesitate slightly...
