Hi everyone,

I have a 2010 BMW E90 328i with the N52 engine. Recently, I noticed the "Service Engine Soon" light. A friend ran a diagnostic, and we found error codes 0029E0 and 0029E1.

What could be the issue?

When starting the car at cold, the engine misfires for the first 10-15 seconds but then runs normally. I haven’t noticed any other changes.

I have BimmerLink and an OBDLink CX, but I’m not sure what parameters to check.

Thanks
