  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...

    Evening everyone. Recently when I've been starting up my car no matter what time of day I hear a sound which sounds like someone knocking in my boot and I have no idea what it can be. The owner before installed a sub and amp in my boot so that's the only thing I think it can be? The only thing...

    Hi all, when i start my bmw 520d in the morning an unusual amount of white smoke comes out of the exhaust. If i rev the engine once or twice it immediately stops smoking. Car feels abit rough on startup but as soon as i give it a rev it smoothes out and the smoke stops completely and it does not...

    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. But I've just fitted a tuning box and it...

    Hi all, hopefully you can help/ anyone has any experience with this? Recently I’ve noticed a puff of smoke coming out of the exhaust when starting each morning. Recently I left the car for 3 days and on startup it produced a cloud of blue smoke! I’ve checked the PCV and looks in good health...

    Hi guys - hopefully (I'm sure it is) a very minor fix/garage visit to fix. 2009 BMW 320i Petrol M-Sport 34000 miles manual When I leave my car for a while, get back in & start it, the idle is a bit rough - the gearstick is more shaky (orange engine management warning light sometimes flashes)...

    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...

    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. There are no other warnings, nothing in the idrive to suggest a problem - and I just can't work out what is causing these beeps, and whether they are...

    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...

    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...
