Car: BMW 2008 335xi coupe. FBO with jb4
Default ALOT of problems. - 09-23-2019, 07:04 PM

Ok, so I'm FBO with jb4. I have *** that always trigger all the o2 sensor error codes and I've tried things to stop it but cant. However, since that doesnt directly affect performance or anything I've left it alone jus clearing the engine light from time to time😪.

Than I started getting the code 2d2e- angle of throttle valve, intake pipe under pressure, correlation. I think researched that it was just a shadow fault code and to get rid of it I should lower menus 10 and 12 but even after doing so I get the code from time to time.

In the last couple weeks I've noticed that whenever I really push the car or floor it, it goes to map 4 (usually run on map 5). Than 2 days ago I stopped at a red light and the engine shut off. I jus turned it back on and it ran almost fine except the bov sounded like it was barely pushing the back pressure out instead of just releasing it cleanly. Than yesterday I started the car and after a long crank it started but was in limp mode with the engine malfunction on the screen. And now today it is still like that. New codes that came up along with this problem are 2a94- crankshaft censor, signal/ and 3100‐ low boost mode engaged CEL displayed (along with the regular o2 sensor codes).

We checked the vacuum line, charge pipe, and bov to no avail. We disabled the jb4 with same results. Al

There are videos with how it sounds starting up and running and turning off that I could email anybody who wants that. Help pls.
