Has anyone dealt with this one? 2008 135i MT. It came on yesterday afer 4 hour trip. The engine has full power, everything else seems normal.

Hi Lester,

Same thing happened to me on the weekend. Car went into limp mode.
Hearing all the bad stories, I left the car running and drove it home slowly in limp mode.

Got home, pulled out the OBD2 adapter and used Torque (Android) to find it was a misfire. Restarted the car and the CEL light was off the car out of limp mode.

After a quick search, it looks like common causes are: spark plugs, injectors and HPFP. If it comes up again, I'm going to start with the spark plugs.

Only had the car for 2 months

Hope yours is easy to solve!

Check engine light, there are 100s of codes that can set it off. On my moms car I blew the HPFP on the drag strip, you will notice restarting it turns the light off until you start driving and it senses another missfire.

This one just required a reset. I was told "a valve didn't open".

I will find out more today when I pick the car up.
