Ticking Vid.. N52

[Taymaishu]

Hey guys,

Here's a vid of the ticking sound I explained a while back and BMW couldn't replicate it...

Any thoughts? I've sent the video to my SA.

Edit: As a note, this was on a warm engine after a 30 minute drive. Ambient temp was around 25 degrees.

Do you mean that high pitched/metalic sound? which only happened a few times?

Yup - it happens when i'm going from 0 at lights, under medium braking, acceleration, or changing direction at very low speeds.

Sounds like your going over a drain cap :P

This might sound stupid but is your exhaust at all loose?

I think it was the reverse sensors :-)

I'll mention it to my SA - never thought that :-) thanks!

And I thought my wife was bad at parking

I could not hear what you were talking about but I did have a period of some funny noises at low speeds ages ago. Wound up putting some anti-squeal paste on the back of the brake pads sorted it.

++1.

Def sounds like something in the exhaust, like a flex flange or something... when the engine moves the exhaust you get that CLANG sound. It doesn't sound like its coming from up front... def from under the car rear/middle of the car.

There is the half X-brace under the car... maybe that is loose. I think it gets close to the exhaust. Or there are a few mounts/brackets for teh center pipe that might become loose.

Good Luck,

Hi mate,

Great! The front cross brace was broken and replaced in July. I will chase this up with my SA as they did the repairs under insurance.

Indeed, it is right under the cabin.

Best,

Tay

I think you are correct mate..Now that I recall, a mate of mine had the same issue after having his mid pipes replaced on his 135i and they didnt tighten up the X-brace correctly..

Agree with above, might be some damage left over from the wound Christine received earlier last year
