    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...

    BMW 3 Series - Tech Talk For All Gen Of 3 Series
    Hi, I have a 2008 E92 320d m sport. It's done about 137k miles. On startup it's started to hunt. It starts up then the revs bounce up and down for a few seconds until in calms down the normal idle. Seems better when it's warmer and worse when it's cold.

    Hello and apologies if this has been asked before... Trying to diagnose a multiple misfire with my E63. When started from cold it runs perfectly. Switch off, go to start again immediately and we then have a very bad misfire and what sounds like poor compression on start up, the engine cranks...

    BMW 3 Series - Tech Talk For All Gen Of 3 Series
    I've always had this and I've never got around to looking into it. Usually on a morning, if the car has been standing for 8 hours or so, there's a squeal or hiss noise coming from the front of the engine. It dies down when you rev but comes back again, after 2 minutes or so the noise is gone...

    Hi all I have recently bought myself a F01 730D, which I am absolutely loving. However, when I press the start button, I get a series of beeps.

  18. Engine Smell and Smoke ONLY on Startup (N42 318Ci)

    BMW 3 Series Forum - Technical Talk on the BMW E46
    So this issue has been happening for maybe the last 6 months or so, so definitely not a sudden thing. But I thought I'd finally ask for an answer. On a cold startup, about 3-4mins after the engine has been running (so the temp needle is just lifting off the blue) the engine starts to smoke a...

    Hello all, I bought a 316i it runs ok just sounds like it is bogged down or something. There is a rattling sound on start up and a delay when you rev. The engine pulls well for what it is and there is a bit of faint white smoke on cold mornings. I'm taking it in in a week or so for...
  20. Slightly rough idle at startup and occassionally at full temp 523i

    BMW 5 Series - Tech Talk For All Gen Of 5 Series
    Hi all. Have a pretty minor issue with my 09 523i. On startup idle is a bit 'missy' but usually settles down after ten seconds. Occasionally, and literally happened 3 or 4 times in my 9 months of ownership, a smooth idle will suddenly drop down to near stalling but recover quickly. Very minor I...
