Half engine light/limp mode when WOT
Hi guys got another problem I'm sure someone can help me with, I go into limp mode/half engine light when I go wot, sometimes the abs light, ftm, and dsc lights come on aswell which is weird. When I put my foot down the car wants to go buy something is stopping it then I get limp mode unless I take my foot off the pedal.
The codes I'm getting are 2774 2c56 2c58 36c9 Hope someone can assist. Thanks |

Well, this is what your codes dictate: 2774 -Mass air flow sensor, plausibility: Air mass compared with model too high 2c56 - Boost pressure control, upper value: Boost pressure too high 2c58 - Boost pressure control, deactivation:Boost pressure build up blocked 36c9 - DME, internal fault: Plausibility monitoring of the relative fuel mass |

Hi mate, did you ever manage to sort this?
I’m getting 2C56 and 36C9, so far I’ve done MAP sensors, checked all wires etc. but not sure what direction to head next. |
