Hey guys I'm chasing an issue I can't figure out.
2007 335i 6mt. Only mods are MHD and a dual cone intake.
Under coasting and light throttle I'm experiencing a surging or bucking kind of feeling. It disappears on deceleration or harder acceleration. I replaced the vanos solenoids but that didn't help. Car is healthy otherwise besides some wastegate rattle.
I'll attach a log I did with MHD. Not a pull as it doesn't seem to occur under heavy throttle. More light throttle and coasting instead.
Thanks in advance for any help
