Can anyone identify this system S54 (M3)
Its at the top right side of the engine bay. Between the firewall and strut. The sensor here was loose / unplugged.
Wondering as I've had a misfire on cylinder 2, mass airflow circuit A low and for some reason my battery drained to 9v overnight!!

Any advice on new front speakers other than Bavauto?
I don’t need a full set, rears are pointless, running fronts and a small sub in the trunk.
Installed a CarPlay unit yesterday, shockingly easy, going to run an rca for the sub to the rear.
