Adaptive Suspension noise when unlocking car?

ajfoggy · 05-24-2015, 01:31 PM

I have noticed my new car make I funny noise when unlocking, seem to come towards bottom of car. Is it adaptive suspension that is making the noise? Anyone else have it that can confirm?

Cheers!

Prob just the fuel pump priming.

Mine makes a noise when I unlock it, sort of a buzz then a click and it stops, doesn't always do it but I'm guessing it's the same thing

Thanks all. I guess that clears that up :-)

My wife's car does it too. You only have to try the boot handle and it primes the pump. Clever really.

Same on M235 and M4.

Can't recall 520D?

Mine does it and it's a diesel. The noise is only for a very short time though.

Some diesels used to prime the glow plugs on opening, so it could be a relay for that?

I assume Nick will be along soon to tell us the diesels do it too, just that us diesel drivers have been deafened by our engines...
