I also threw P2AAF and 29F3 starting a few weeks ago. 2010 E92 N54 45kmi, Cobb stage 1 Agg. Initially dealership said P2AAF didn't require action.
Then over the holidays I was literally driving 1 block from dealership when car went into failsafe. Pulled over and saw P2AAF and P29F3 on Cobb, in addition to a new P29DC. Obviously a fuel issue. I was able to limp up the street to the dealer.
They replaced low pressure fuel sensor and now all is well. My SA said that this is "becoming very common". Seems like a lot of people are having this issue. Is there a recall on this part?
