- 335i M-Sport Package
- Convertible
- Purchased from second owner with 40,000 miles in June, 2017
- PPI performed by Northeast Motorsports in Mahwah, NJ (http://www.nemotorsportsllc.com/) turned up no issues
- Presently 46,500 miles (6,500 miles primarily highway)
I brought the car to Rennsport Motor Works in Hackensack NJ (http://rennsportmotorworks.com/) and after what seemed to me to be a substantial amount of diagnostics work (a few days), they focused on the eight occurrences of the “charging pressure control” failures, and replaced the boost pressure sensor. Below is a link to the invoice for the work performed and details of the diagnostics.

Five minutes after I left the shop, I attempted to recreate the issue and was able to do it on the first try. I dropped the car back in the shop the next day. We’ll see what the shop comes up with as they continue to diagnose, but I’m losing confidence and rather perplexed. Does anyone have any experience with an issue like this? Any thoughts would be greatly appreciated.
