I recently had my 435i in the shop to put the stock catalytic converter on and I also replaced ofhg, drive belt with tensioner, and cylinder head cooling hose. I also flashed from stage 2 to stock with bm3. And I have fbo with upgraded pure 500 turbo. After driving the car stock I’m getting a whole bunch of codes with drivetrain malfunction. Here’s all the codes:

MAP: Stock Tune
CODES: 120308-boost pressure control,plausibility; pressure too low.

190F08-tank ventilation system, Malfunction
(I’ve had this on the car for a few months now)

118002- Mixture Control: Mixture too rich

20AD09- Engine cooling system, Additional cooling pump speed outside of tolerance

1C3002- Engine Oil pressure sensor, electrical: Short circuit to ground

Then there’s 2 other codes that bm3 says are inactive:

11CF30- Mixture control: Group Error

108932-intake air temperature sensor: Group Error.

Any ideas? I’ve heard that running a stock tune with upgraded turbo can be bad for the turbo so should I at least flash it to stage 1?

Getting the same codes: "11CF30" and "118001" (fuel air too lean). Car is MHD stage 2 with supporting mods, pump 91, 90k miles. Car drives normal, idle as it should, should also point out that I made the switch from E20 back to pump not too long ago, still running stock HPFP and LPFP.

was wondering what was your solution? any leads for me? cheers!
