Ive been looking at the forum for some help but dont see anyone having the same issues as me. I have a 2013 335is and it’s fluctuating aggressively at idle trying not to die. I have these codes. I did replace the throttle body thinking maybe it was that but it hasn’t helped(bought the Amazon one because i didn’t have time to wait in the fcp euro part, i can get that one if yall think its recommended). Could it be the wastegate? Any help is appreciated thanks

Wastegate is normally open and at idle it shouldn’t be actuating so I wouldn’t think it’s the wastegate. Are you able to send a log at idle?

Have you reset throttle adaptations and waited the 30 seconds stated by MHD before turning on the ignition?

I dont have logs but yes i did the reset a few times and it tends to make it worse. If i let it run ling enough it get used to it and only at some stop does it start surging again. Just to confirm the reset procedure is key in, press start, push down accelerator past kickdown for 30s, press start, release accelerator and then wait two minutes?

I'm not sure about the pedal method but the throttle adaptation reset can be performed through MHD under the codes tab and then reset adaptations. Choose the throttle option and then turn off the ignition and wait 30 secs before starting the car. Waiting the 30 seconds is very important, otherwise your throttle will oscillate upon next start up.

When you changed out the throttle body, did you also replace the throttle body to intake manifold seal?

Try the throttle reset through MHD and if that doesn't help send over a log at idle.

Also, when did this start happening, did you do any maintenance, tune changing, etc. that could've caused this? Or did it happen out of the blue

I’ve been clearing the code for a while but it never caused throttle fluctuation and when i cleared it would stay gone for a few weeks. Well now it instantly comes back and is throwing both engine lights. Heres the log btw[ATTACH]undefined[/ATTACH]
