  1. General E46 Forum
    Hi everyone, This noise might be split into two.. The loud ‘pop’/knock when shifting between reverse/drive/park etc is very loud and noticeable. I have been told by mechanics it is likely backlash in my diff.. Second, is a general knocking in the rear when making sharp turns/ going over...

    Hi guys My car has been making this strange knocking noise. I was hoping it would go away after replacing the ccv lines but it didn't :( I've replaced the Maf and the disa valve also. When replaced the disa valve I got one of the repair kits and I didn't tighten the bolt as snug as it could be...

    I have an 02 325xi with 160,000 miles. I have knocking/thumping coming from the rear while accelerating, always occurring at 2500RPM. Took it into the shop, was told it is the rear U-joint failing. They quoted me ~1100$ out the door to replace the entire driveshaft. I haven't been able to find...

    Hello all, I've searched a bunch of threads on the forum regarding driveline noises and knocking, but I've hit a dead end. Some context: A couple of months ago my E46 318d started banging / knocking a little bit under heavy acceleration in first and second gear, or when gently accelerating...

    Hey guys, been a lurker for a while--lots of good DIY stuff here so thanks everyone for contributing. First time post for me Just did my oil filter housing gasket on an 01 325i. Pretty straight forward job. I put everything back together and started her up and the engine is making a pretty...
  8. Suspension & Braking
    hi everyone. I'm new to E46fanatics and really need some advice and guidance. I have a 2002 325i (facellift) and recently there has been a knocking noise coming from the front left wheel. It used to be hardly noticeable but it's starting to get louder by the weeks. I only notice it at low speeds...

    I'm hearing a slight knocking noise when the revs are coming down. It only happens when the clutch pedal is not pushed down and the car is in neutral. When the clutch is pressed the engine is crisp with no noise. Also hearing the same noise when I turn off the engine and the clutch isn't...

    Hey fanatics! Long time lurker and reader, but I haven't posted much. I'm having an engine sound issue with my beloved 330i. Long story short, after initial start-up there is a persistent rattle or clicking sound coming from the engine. It appears to come on once the car has sufficiently...

    Just bought an 03 zhp sedan w/ 145k and I love the car except this one issue. I've had it about a week now and it drives flawlessly once it's warmed up, but every morning I experience the rough idle and a violent shaking. By the way it's about 80 degrees so it's not an ambient temperature issue...

    Hi all, I've recently noticed a deep sounding knock from underneath my car, usually between when I decelerate for a corner or lights and then accelerate away. I haven't been pulling away too quickly (£1.30 per litre/$7.50 ish USD per gallon soon makes you watch your speed ..... now and again)...

    Below is a link for some audio I recorded of the noise: http://www.youtube.com/watch?v=lPIjHTQ2xFQ&context=C2b40cADOEgsToPDskJMqxo6Lw9L1b6360mw9unK It only happens on a cold start and the frequency increases with RPM. After hitting 2,000 RPM or warming up, it goes away. After searching...
