Clicking Noise

ZachEvans93 · 08-13-2022, 12:49 PM

Hey gents,
New here and new to the BMW world. Recently traded my Supra for a 18 M4 Comp. I am running BM3 stage 1 tune. I brought it to the dealership a few weeks ago to have them look over everything and told them about this noise. They stated everything was fine but it sounds terrible IMO. I know this isn’t the HPFP or anything of that nature. It seems to do it once it is warmed up and under a load. At higher speeds you cannot really hear it. I thought it might have been a exhaust leak but after putting it in the air I could not find one. It sounds like a card in a bike spoke if that helps. I tried to make a video but you cannot hear it. Any help is greatly appreciated.

is it manual ? sometimes the ebrake cable gets loose and slaps the driveshaft. its a pretty loud slapping noise and only happens under load.

Yo!

A few questions.

- is it wheel speed dependant? or RPM dependant?
- Where is it coming from? front, back, midde?
- It is only when it is warmed up?

That may help us narrow it down.

One common issue that comes to mind it a rock stuck between the rotor and the back plate of the rotor. It makes a horrid, metal on metal type sound. Luckily, backing up a ways usually knocks the rock or whatever is in there out.
