2009 335i threw code P052B

Somewhat new to the forums and want to pick some minds about my code p052B. It happened after two 30 mile trips (gassed up in middle of trip). Shutting it off, then starting up. The code happened and my car went into limp mode.

Restated it at home and it acted normal again, but hooking up an ODBDII to it and pulling codes showed a P052B Powertrain 'pending fault'.

My 2009 335i has almost 50k miles on it and was bought as a CPO. So should I take it to the dealer or an independent shop to check out? Or is there anything else I should check on my own?

Any tips would be appreciated. Thanks.

More details, code will not recreate and was 'pending fault' it no longer logs in the ECU. So maybe it's a freak start, or indication that something is on it's way out.

Thanks, I found the first thread (with google), but not the second. I'm going to let the dealer have a look. The problem hasn't come back after 2 other drives today, but I want to be careful regarding that mulitple things than can cause this code to come up. Since it was a 'pending code' it no longer shows up now when I do an obd2 scan so it's a good thing had one on hand when it happened.

Correction ... obd2 code readers has 2 read codes options .. ' pending codes ' and ' history codes ' ... pending means the fault is still there at the moment ,when you restart the car and its runing good you wont find any codes pending because the fault is not there anymore . However codes are stored in the ecu and you.can get them by reafing history codes

Yup. I'll eat it at the dealer and hope the CPO takes care of it if anything requiring fixing comes up.
