I’ve been battling with code 29D2. The car misfires like clock work at 6400 rpm.

So far I’ve replaced the HPFP, injector for cylinder 6, HPFP sensor and pre cat o2 sensors. All parts are brand new OEM.

My setup is a e92 xdrive automatic with hybrid turbos and all supporting mods.

I’ve read that the auto transmission can cause a false knock and can be desensitized. But the AFRs look really suspect.
What do you guys think?
