Fault codes need help.... - BMW 3-Series (E90 E92) Forum

broker335xi · 03-27-2012, 02:02 PM

Hey guys..

Just got my 335xi back from the dealer. They replaced 3 injectors, HPFP, thermostat, and DME from what they said.

Anyways i get it back and I'm concerned because I still had my Cobb Accessport installed. Car runs great no problems or error codes.

I would imagine if they replaced the faulty DME with a new one my tune would be gone as well....

My tune is still programmed in however. On top of that I pulled error codes H2F81, H2EE0, H2F84, H2F83.

Does anyone know what these are and what they mean? Thanks.

Well if cobb is still installed it means they did not replace the dme or flash it with new software.
For the codes search them up.
U 100% sure you are running a tuned cobb map?

That's exactly what I thought as well although my receipt states otherwise.

When I plug the Cobb in and view current map it shows up.

I tried searching those codes and I didn't come up with anything.
