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.

If your running over stock boost on car spend $30 on BMS intake cupler next your could be sucking the stock POS closed

I had similar problem and spend way to much time and money chasing it

He's talking about the upgraded intake coupler offered with the BMS intake https://burgertuning.com/collections...ormance-intake. Not sure if sold seperately but defiantly recommended if pushing boost over stock. I'd shoot them an email and ask. If you don't already have the BMS intake (should buy), I'd lie and say you bought the car aftermarket with the filter already on and want to buy the coupler separately
