Limp Home on Code 2B27
Hello all,
I have just had my first real issue with my 09 E90 M3 DCT, when I was using it for some run-around stuff in town. I started it 6 or so times doing my rounds and then on the last start to head home it went ape poopy! Limp Home mode, DBC & DSC malfunction! Fine, but then I shut it off and tried to restart and that's when things went really awry. It then would barely move. Got the BT scan tool hooked up and it had codes a mile long. I then reset it and all was well again. Few days later the limp home mode came back and I scanned it before I shut it off and I got a 2B27 along with the normal 2B57 and 5E19 for shutting things down.
So, I have not seen much about the 2B27 code - Throttle Flap Test Reset Spring. Sounds like I will need to go back in and check on the Delrin-Brass gear set I put into the throttle actuators and then check the boards for cracking on the Mosfets. Is there anyone else that has seen this code alone without the dreaded 2B26/2B29?
Thanks for any advice.
