  1. F10 / F11 (2011 - 2016)
    Hi all ! I've been having an issue lately with my 2010 520D SE (F10 Manual). Have got this diagnosed by an independant BMW specialist mechanic and a general mechanic. Their diagnosis didn't seem very promising. So it started like this.... I randomly checked my oil level on iDrive and it shows...

    I drive a 1996 328i and it has a ticking/knocking noise coming from the engine bay. Does anyone know what this could be? Video: https://www.youtube.com/watch?v=6hL0i8hgJJU What I know: - Coming from the driver side. Appears to be lower - I notice the most vibration from the noise when I have...

    Hi, I'm new on here, my BMW F30 (328i xDrive 2013) was driving great on Friday, minutes later, I get an alert saying "Engine oil pressure is too low" I pulled over, got it towed to the shop. Now the engine isn't starting up and they say I need to get a new engine! I am steady with my oil...

    Hey everyone, I have a 09 E60 528i. Occasionally I'll hear a metallic-like rattle/knocking sound coming somewhere from behind me. It sounds like something metal knocking against something metal. It usual occurs when I hit a pothole or a bump just right, however it doesn't always occur. It's...

    Car: E90 BMW. 2006 330xi 6 speed N52 engine. Details. I have scoured all other old posts as well as other forums with no solution. Any insight or ideas would be appreciated. I am hearing a knocking sound coming from the front of the car, maybe the steering/suspension or engine compartment. I...
  6. F10 / F11 (2011 - 2016)
    The other day when I got in the car and powered my air on low, I began to feel a light knock from the engine hood. After driving down the ramp of my parking garage and blasting the air, the knock got louder and the car began to stall. When I parked the car and turned it off, shortly after...
  7. E60 / E61 (2004 - 2010)
    Hello fellow members. I just signed up today and wanted to see if anyone knows exactly what causes the 'Thump' when starting the engine. I just brought a 2008 530i with 102,000km. NZ NEW and service history from new. Some days it thumps more gently than other days. Hot or cold it still...
  8. E85 / E86 Z4 (2003-2008)
    Hi everyone! I seem to have an intermittent problem that comes and goes and relates to my powertrain. Usually during damp weather or after a motorway journey doing a constant 70mph (this may be in my head), i get hesitation during acceleration with partial throttle in any gear and any rpm but...
  9. E46 (1999 - 2006)
    when i pull away i get a engine knock in first gear. Any ideas of what to do? Car runs great, still get advertised milage at 140k.

    Alright, so you guys helped me get the hood of my new E39 open, and that leads to this follow up. I have just picked a 2000 540i/6 with about 150k on it. Super clean and perfect pretty much everywhere, but engine maintenance has been deferred, so it's suffering the consequences. I got an...
  11. F10 / F11 (2011 - 2016)
    Hi All Well I'm the proud owner of an F10 now (growing family), having just bought it last month following the untimely 'death by idiot'* of the trusty 3-series. Starting two weeks ago, at very low speeds, there is an intermittent "knocking" sound AND sensation through the steering wheel. I've...

    Hi! My 99 525 TDS makes alot of noise on idle ( low load) I suspect it might be the injector pump timing or the hydraulic valves knocking but it seems unlickley :dunno: Is there an easy way to adjust the pump timing? my guesses is that the timing is adavnced from when the pump gaskets was...
  13. E36 (1991 - 1999)
    I am experiencing a weird knocking noise coming from the right rear side of my 1993 325i. I thought perhaps a bad boot in my CV shaft but upon inspection, they're fine (wasn't as rhythmic as split boots can be either). The knocks come and go, usually when starting off slow and slowing down. But...
  14. E39 (1997 - 2003)
    It may be impossible to determine, but, I ask because it would be very useful if we could determine whether the piezoelectric knock sensors have activated in, say, the last FTP. Is there any register that holds a value that we could read after the fact which would tell us whether the knock...
  15. E36 (1991 - 1999)
    Hey i have a e36 2door bmw. i was driving when all of a sudden my rear end produced a loud knock/clunk sounded like diff but was more open, like a diff nock has an enclosed deep nock, where as my bmw has a real loud knock from the rear,sounds central and can hear very clear at any kmph. i...

    There is a knocking noise coming from the rear passenger side of my car. Its not the shock absorber or mount. My friend and I think it is my CV Boots that need to be replaced due to them being split. My questions are if anyone has experienced this before, if replacing the boot will fix the...
  17. E46 (1999 - 2006)
    Sorry to have a few different threads going but I have quite a few issues! :( This one: When I'm letting out the clutch, there's a "clunk" coming from the rear. Reverse, 1st, 2nd....whatever. I can sit in reverse and push clutch in,out,in,out and hear the clunk every time I let it out. Only in...

    2001 530i automatic. Three days ago spontaneously after the car reached operating temp and while idling in park the idle became very rough. Rough enough that I thought it might die, it didn't and I drove it back home. Acceleration was hesitant at low rpms, car seemed to run fine at higher rpms...

    Im replacing knock sensor 2 for cylinder 3/4. Whats the easiest way to do this? I did the intake manifold gasket but didnt know until after the fact my knock sensor was bad. I know its bad cause I got the code pulled. Also sensor plugs in on the black box under manifold, correct?
  20. E46 (1999 - 2006)
    A few thousand miles ago, my engine started to - apparently - burn oil. (Oil level keeps getting low, but no signs of leakage anywhere) I took it to my mechanic and he replaced the valve cover gasket. He also did a Service II. Problem persisted. He told me it may be a faulty sensor... but the...
