ticking sound from engine bay when unlocking?

so i just noticed a bizarre ticking sound from the engine bay when i unlock it?

the engine isn't running, this is straight after i press unlock

quite loud, anyone know what it is, and if there is a fault?



thanks,

I'd be embarrassed if my car did that. Afraid everyone is thinking my car is broken and I can't maintain it cause I'm broke or dumb. So if it's not normal but doesn't do harm, I'd still want it fixed.

I heard this for the first time today - my car had not been driven for a week. I won't be happy if this continues, especially while its under warranty! Other thread hinted at possibly being a fuel pump issue or even ASD related - does anyone even know at this point?

reading through, potentially, it could be the fuel pump or the valvetronic motor

There's a thread on the m3/4 section with this. The few that got their dealer to fix it got a new valvetronic motor. One guy said it came back 3 weeks later. Many just ignore it too... Probably the owners that lease ignore lol

Probably worth mentioning to the dealer, i would definitely push for a replacement if there was a redesigned part in the future?

I told them multiple times and sent several links! They either don't believe me or click on the links. Or want confirmation from BMW and not random internet people lol

If you do bring it in, expect them to have your car for over a week. Seems many had their dealer keep the car for while. Maybe you'll get lucky and your dealer will know what to do and do whatever fix asap.

When they were trouble shooting my car, mine had no codes and they tested the valvetronic motor and everything passed.... But still randomly ticks at me. I tend to bring it back in for round 2 eventually.

WTF? Dude...if you work for ASIS (the Australian version of the US CIA for the lesser informed)...DON'T START YOUR CAR!...or...load up on life insurance and get your wife to start it.

More seriously...there is no way that is "normal"...I would insist on dealer replacing whatever part is making that noise. Something that loud and obvious, there is no way they "don't know what it is."

P.S. Just thinking that "ASIS" is awfully close to another organization...you guys might want change that.

This is a know issue with the N55 and S55 engines. It is the valvetronic motor making the noise. Bmw has the issue under investigation and any parts replaced right now might not fix the issue in the long run. They have been requesting parts back for testing.I would wait until there is a permanent fix before bringing any car in for this problem as the problem keeps coming back for most cars. I can post an update when I get more info on a fix.

Sometimes mine does it and sometimes not...... last night when I was doing some more Bimmercode coding and trying to get the BM3 up and running it did it all the time the car was on. That would be for hrs.... sometimes really loud and sometime not so much

Sounds kinda familiar...





In all seriousness I'd take it to a dealer and show them the video as well.
