Hey , my r56 S was running perfect , yesterday i was driving at 50 mhp a suddenly the check engine turn ON!! 2 week ago i added a downpipe.
this are the codes:
P2270
P2A74
P2A7F

HELP plz

 

Your code is P2270 O2 Sensor Signal Stuck Lean (Bank 1 Sensor 2).
The other 2
P2A74
P2A7F
maybe someone else will know as I don't see them listed anywhere.

you don't mention if it is a catless DP. If it is with any catless downpipe you will get a check engine light, but you can bypass it with the accessport.

 

thanks, yes its a catless DP but i feel the car no having full strength. and sound wierd. i cant find the other 2 codes.

 

What type of scanner did you use?
Because some generic OBDII scanners provide misleading P-codes as the programming doesn't match to the MINI's on-board diagnostics protocol.

i used a COBB accessport to scan the R56. But yesterday, when i started the mini in front of the mechanic the CEL turn off, he scand it and there were no fault codes!!!
