Over the past few months, I have had this intermitting CEL. When it pops up, no information on IDrive is identified. After I drive a little bit or fill up, it disappears. I figured it was either the active grill or other active louvers (common on the G05) or fuel quality issue.

I was picking my car at the dealership last night, after finally finding snow tires for my 21's, and as perfect timing, a CEL pops up. My SA is a legend, sent him a quick text and he ran the car into the tech to pull codes.

"121302 Charging Pressure Sensor 2, signal: Pressure too low during after-run"

Can anyone provide any information on this fault? Tech said it was the first time he has seen this on an X5 and M50i.

Mods: High Flow Performance Air Filters, X5M Resonator (without the silencer tower), RaceChip GTS Black (Head unit removed for service, wiring harness still on, so not installed when CEL came on, driven 100 miles after it was removed, also, the CEL has come on when everything was off too.)

I appreciate any positive insight.

Cheers

Still hopeful someone can help out.

Take it to the dealer, they should be able to pull the code and diagnose if there is an issue.
