I have problems with my 2012, 2 2 diesel and have observations here.
Intermittent hand brake and stability drop outs. Handbrake does work and things reset each time. The actuator drives to the service position ok
Engine goes into limp mode most days. Reader says imbalance on airflow, but replaced airflow and pressure sensors, still the same.
Maxi diag says GWM gateway fault and PAM parking assist control module fail.
Could the battery cause this? There is a permanent battery fault indicated on the reader sometimes?? Don't know if the battery has been changed and registered to the system, its a new car to me.
Any help appreciated.

 

If it's a new car, it may have sit on a lot for a while and the battery drained, then they jumped it without doing a battery reset, I would replace the battery, in this case to get a new start ,and have it reset with SDD PREFRABLY AT A Dealer then go from there, or if you have a icarsoft v3 you can go that route
