30ff help?

lemansbluen54 · 05-04-2022, 04:30 PM

Hi guys, recently purchased an 09 msport 335i 6MT, car came modded with the following issues as well.

Have these showing as shadow codes. Car has the following mods. Loads of what seems like wastegate rattle.

BMS Intakes
ARM Catless Downpipes
ARM Charge Pipe
Tial Blow Off Valve
Muffler Delete
ARM 5" Intercooler
Catch can

Clear and ignore - If the 30ff comes back you`ll know - ask us then

The other two will be permanent shadows due to catless Dps

Weird, my last one didn't have those shadow codes. The 30ff came back as a shadow, and when I cleared again, it came back as a fuel pump plausibility code.

Check your vacuum hoses.

Any one to look for in particular? Bought the car a week ago and it seems like the last owner replaced all of them with silicone hoses

Doing a smoke test is a good idea as well.
