Clicking Noise Every Morning
I am getting a click noise every morning when I unlock the car. I can hear it from the outside once the car is unlock, coming from the passenger side of the engine bay. Anyone who is familiar with how the car's electronics are sequenced to start so I can self diagnose what is making the noise? It is right after I unlock the car and before starting the engine. It runs for like 20-30 seconds and then disappears. Could be the headlight or something?

Had the same issue when it was totally stock. Not normal. I would recommend you take a video and take it to your SA at the dealer to get it fixed. It'll cause premature wear on the VVT actuator over time.

It could be valvetronics like the others have said, for me it only rattled upon unlock for a couple of seconds and stopped. But it's all good now after it was replaced.
If it is valvetronics it could be the following: 1) valvetronics motor 2) eccentric shaft 3) needle bearings

I have made an appointment with the dealer. Thanks everyone for the great info. I will report back once they complete the diagnose. Right now the ticking doesn't happen all the time. I do have a video as proof but still fingers crossed that they will be able to replicate it.

Brought the car to the dealer, left it overnight, the noise just wouldn't come up. They try to re-program the car per BMW's repair manual and found the speaker amp not responding. Got that replaced but they wouldn't touch the valvetronic motor. Had a small argument that led nowhere and end up giving in to the dealer. Now it is warmer outside, the clicking has not come back since. Warranty is running out this summer, I guess I will be on my own. May consider getting an extended warranty once I can comparing warranty price against the cost of a valvetronice motor replacement work.

If that doesn't work go to a different dealer.

1) Valvetronic motor + all the seals and screws that are 1 time use. 2) If 1 doesnt fix it then valvetronic motor + eccentric shaft + all related accessories. 3) A brand new head.

Oh. I think I might only get to the 1st stage. With the weather that is warming up right now on the west coast, the ticking has became less frequent.

For me and a few others weather did not influence the clicking and we had repair 2 done, never heard of anyone having to replace the entire head though.

Remember to check your car after the repair to see if the issue went away. For some of us the issue got worse and we had to get repair 2 done, because the issue may actually not be the valvetronic motor but actual be related to the needle bearings, the eccentric shaft being marred etc.

Does it only happen at 1/4 or less tank of gas? I have noticed a similar sound but only when the gas is on the lower end. something to do with priming ? Took it to the dealer and was not able to replicate the sound. since then i have tried to keep my gas full and havent noticed the sound much.

The only thing that makes sense is the valvetronic motor which actuates itself in a sort of calibration sweep everytime you open the door or wake the car in a 30 second window.

It seems like that has solved the issue on your car.

When my valvetronic motor went I had this. Replaced it and now car is so strong and happy. Sounds louder. Super smooth. Honestly the best it's ever been, weird. Wonder if it was flagging for some time but not critically failing. We will never know.
