  1. BMW 3 Series Forum - Technical Talk on the BMW E46
    Just got the car. 18 years old, 40 thousand miles sat around for 4 years sorn. One owner, I did an oil change. I was wondering is it normal for the engine to run rough for 1 minute then smooth off or is this a sign something is needing fixed?

    Hey guys, I've been having some issues with rough idle after stopping the car and putting it in the neutral (manual gearbox). I've already replaced the MAF and the Idle control valve but that didn't help. I've also replaced the O-ring on Disa valve. The idle sometimes falls really low and the...

    I replaced the starter the other day and now the car starts fine, idle is ok for a few seconds and then it starts going up and down as if it's about to die. When it starts this mood swings, a yellow warning indicator in the middle flashes. The EML light is constantly on, but only the text one...

    Hi, looking for a little advice regarding the title above. I have a 2014 F15 X5 30d (I'm told with the 8-speed box) that I have noticed in the past couple of weeks has started to feel 'rough' when downshifting into low gears. I would say it's noticeable below around 25mph when slowing down or...

    Hi, i have had my 1997 328i coupe for over a year now and a while ago it started developing a problem where it would cut out. I took it to a garage and they replaced the cam shaft sensor which fixed it for a while and it completely stopped cutting out. A while after it started having a problem...

    Hi all, Having just fixed the roof myself and the dsc she’s decided to present me with a new problem - a rough idle. This has been getting progressively worse, which I initially put down to not driving her much but after inspecting in more detail I suspect the oil leak in the attached photos...

    Sorry if this is posted elsewhere, I have tried searching but I keep getting errors on the forums. My '06 320d auto has developed a fault where it is really, really rough on starting (lumpy engine to the point of cutting out, tons of black/gray smoke from the exhaust etc.), but is fine once...

  15. BMW 6 Series - Tech Talk E24,E63,E64,F12,F13
    Hi all! My 630i (06 plate) occasionally idles very roughly indeed. It literally shakes the car at lights/junctions etc. Whilst exhibiting this issue, the power also comes in spurts and surges, making driving on a busy street both embarrassing and a bit frightening! Also whilst exhibiting this...

    I recently purchased an E93 330 N53 AUTO with 105K I noticed a rough idle particularly after a good run or when the engine is warm. It would start to hesitate on acceleration and RPMs drop and occasionally it would cut out. From cold it usually starts fine and drives ok. It pulls through all...

    Hi, I've been suffering from an intermittent rough idle when the car is warm for a few weeks now but this is becoming much more regular. I initially (incorrectly) assumed it was ignition related and either a coil or plug was at fault. After changing the plugs and checking the coils the problem...

    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...
