  1. BMW 5 Series - Tech Talk For All Gen Of 5 Series
    Hi I have moved up to a 2005 530D auto. It has the weirdest problem which I can not sort. Start the car, revs and runs fine. Remain in Park. Take the revs to 1500 or over and it will mis-fire once, engine management light flicks once, revs drop and then all is fine. This will also occur if I...

    Hello all, Let me apologies if this has been posted before but I’m out of idea’s what can be done. I have recently had my clutch, dual mass flywheel replaced and also a major service done all at the same time. When I got the car back it wasn’t running quite right but I thought it would be...

    Hello everyone, I have a 2004 320d touring and I'm getting a ticking kind of noise from the engine when accelerating in first and second gears, perhaps even third but if there is ticking it's nearly inaudible. This only happens at around 2000 rpm to around 3000 rpm. Additionally my car seems to...
  6. BMW X Series - Tech Talk For All Gen Of X Series
    Hello, My X3 isn't running well, as above the idle is rough and the engine is hesitant below around 2000 RPM. If I disconnect the vacuum pipe from the EGR valve and plug it, the engine runs fine, although with the EML showing. I'm assuming that the fault is somewhere in the EGR system...

    Hi, I've had an auto 2010 330D for the last few months (very low mileage for the age, 47k). Once I got used to the constantly shifting gearbox (my last auto was a 3 speed), it's been a blast to drive. However every so often (but twice on my way to work this morning) I've experienced some...

    Hi, I own an E36 328i (1998) and notice it has been extremely thirsty on fuel - around 56 miles to £20 (V Power) The car also cranks a few times before starting but idles clean. When driving the car it also seems to sometimes stumble or have a flat spots in certain RPM ranges. Would anybody...

    Since I bought this 330cd a month or so ago it has only revved to around 4020rpm whereas it should go up a bit higher. I've searched through forum posts but been unable to find the cause of the issue. The seems to drive fine as far as I can tell and pulls well up to 4000 in any gear I've tried...
  10. BMW 3 Series - Tech Talk For All Gen Of 3 Series
    Good day forum members I am new here. I bought my first BMW (fell in love with the brand after driving a few E46's, an E90 and new 1 and 3 series). I am in love... and perhaps I may be overly cautious here, but I noticed something after using the car for 2 weeks now. I owned old diesel before...

    What do they mean? Do they measure oil or coolant temp? Am I safe to rev the car as long as I rpm is lower than the line?

  14. BMW 1 Series - Tech Talk For All Gen Of 1 Series
    Hello everyone, I'd really appreciate some ideas on how to diagnose this issue(s). Car: 2005 120D M47 engine. Issue: The car runs really rough (like a misfire) and creates lots of grey smoke from idle up to 2000 RPM, at 2000+ RPM it runs OK. A diesel engine specialist has tested all the...

    https://www.youtube.com/watch?v=aYFLSnUIvoA&feature=youtu.be Any ideas what this might be. Something loose perhaps? Only happens at very low revs. More annoying than anything else as doesnt have any impact on performance. Thanks

    So I'm casually driving my car, already on the road for like 10 minutes, engine warm, cruise control on, rpm about 2900, everything allright. I hold the cruise control paddle to put on some speed, suddenly in the exact moment I touch the CC paddle, the rpms INSTANTLY drop from the above...

    I replaced my rear muffler with a straight pipe and testing it before rolling off the ramp, by revving the engine and checking for leaks. I couldn't hear anything, but on my way home I heard this inexplicable noise. You can hear the sound at 3 seconds, and again at 5 seconds. It's only right...
