have you check whether your battery terminal is loose?

usually, the panel beater like to disconnect the battery when they are doing the repair.

what are the error code presently recorded in the shadow memory?

 

[anaksarawak]

Too many bro, mostly due to failure of communication between gm modules

My mech found a burned wire from radio today near the aircon to gm module

Hopefully that is the source of the problem.

D black E46 318 Ci at Kuchai urs?

 

[anaksarawak]

Yes bro that's my baby. They found 5 burned wires. All due to improper connections or grounding of aux power for my GPS and galaxy.

Advice to all, don't mod your car's electronics unless the add on are custom designed for our cars

Got my car back and everything is back to normal now

Status:
Since the wire burned it also damaged two items ie Ignition switch and brake switch, cost me RM140 for both

Labor cost to find the problems and rewire RM450


Ignition switch

Brake switch
