When Im in the car and the windows down rolling slowly next to a building or something that echos I can hear a clicking that I think is coming from the rear. Has anyone noticed this noise? My salesman is calling me in to test drive a RCF so when I do that I'll have them look at it.

Could be the rear calipers I know its usually normal but depends on the clicking, shouldn't be seized up this early, I know that was a common issue.

Check for nails in your tires. If you speed up and the clicking speeds up, that is a possibility.

Doesnt feel like sticky calipers honestly. No nails in my tires.

You may be mistaken about where exactly on the car the clicking noise is actually coming from as you travel slowly next to a wall. Does the noise change with only ground speed, or does the noise change with engine RPM speed? Are you sure the clicking noise is not coming from the engine? It could be just the [normal] sound of the high-pressure fuel injectors clicking? Or it could be the high-pressure fuel pump, which feeds fuel to the injectors.

More than likely it's direct fuel injectors. they click. Soundproofing makes it harder to hear inside the car with windows up.

I had a thread about this back in 2012 when I first picked my car up. The sound came from the front wheels whenever going around a bend at speeds less than 10 mph. Some said it was the rotors. After I had aftermarket wheels installed, the sound mysteriously disappeared though.

Yeah I'm all too familiar with the loud *** injectors. All of the turbo I6 powered BMWs have piezoelectric injectors aka louder than Toyotas GR series lol. The click is slow and definitely from the rear. It sounds like it clicks along with the rotation of the wheel. I just backed my car into my car port and heard it again while reversing.

Its only show driving or is it when stopping at slow speeds.
