[300hp]

I posted in my "well if you have a BMW you will have to park it...."thread that I was observing this issue. It seems a floodgate of issues got me at the same time.

iRO of the ticking sound this only happened after driving for say 5 miles. Every time at idle I would hear this sound and it was ANNOYING.

I have a 528i as a loaner with the N20 and that ticking sound is the same as on the N20 at start up. The ticking sound goes away once you drive off in the 528 and never comes up until the next day at start up.

However in my case the ticking sound could not be heard with the hood open. Only when inside the car. My dealer said there was a tube they had to close and fixed the issue. I am yet to test drive it but am waiting for the new DME.
