Rough idle, stall, limp mode. Help

Allspark82 · 03-28-2019, 03:04 PM

Ok so bought a 325i n53.

Limp mode, rough idle, car shakes. and following codes.

2c7c
29f2
2b05
3aaf

I replaced the nox sensor and that code vanished.

Wondering if hpfp has gone or something else giving false codes

I had the rough idle and car shaking issues on my e90. Turned out to be the vanos solenoids. I took them out, cleaned em then put them back in. I don’t know much about the N53’s but a quick google search to see if that could be your issue wouldn’t hurt.
