Car: BMW 440i xdrive
Default B58 Codes - 07-05-2020, 04:05 PM

Hi, everyone!
My car is bmw440i xdrive with JB4 map 2, catle$-dwnpipe. I got a long trip (700 km, avg. speed - 160 km/h) during which my speed could be stably 170+ km/h for more than 1 hour. After this I got the following codes:
101F01 Throttle valve opening angle pressure — ignore, tuner code;
118001 Mixture ECU: mixture too lean;
102001 Air mass, plausibility— tuner code, ignore;
180001 Catle$-dwnpipe detected.
How serious is this? What should I do with it?

Look like typical ignore sorts of faults due to the mods and not indicating any actual tuning issue with the car.
