Hi all

I have a 2015 228i. N20. Basically I'm getting some intermittent errors with my piggyback ECU.

I have one of these which in the UK is fairly respectable although not as good as a custom tune(mine has warranty).

I also have a Mishimoto intake.

On the freeway/motorway at a constant speed between 70-80 mph I am getting an intermittent problem at which point the car is going into limp mode and I have to switch of the tuning box.

The errors I get are:

B2AA
P110D
P1AA
P169F

They all seem to relate to the throttle position. However running the box is there anything else I should be checking. I have new spark plugs on order and the car just had an oil change/service. I am running 99ron all the time.

Many thanks

maybe check your ignition coil packs?

Definitely next port of call following the spark plug change!
