Air sound n54

[one35eye]

Hi Guys

I have an n54 so I was wondering if you can help me please troubleshoot a sound I have on my car. It's 2008 135i with a air sound coming from somewhere I can't find.

Hi...

Check the clamps and all connectio s from inlets to the stock air on (intake). If you have an aftermarket set of intakes, check them out.

Do you have a loss of power?

Sounds like a major boost leak. No warning lights?

Hi Guys

Thanks for the responses. Turned out to be torn diaphragm on bovs. Much appreciate the responses.

Very surprised you didn’t get a 30FF
