Today was a good day to be a Perth mobile mechanic ! Today we had a gentleman contact us requiring a Mobile mechanic to come to Greenwood to have a look at his Holden dash problem so we sent out a mobile mechanic to check it out ! When we got there we found the car had been jump started incorrectly which caused the Holden dash to flip out and required some car repairs ??  So we plugged in to the Holden ECU and cleared all faulty dash codes and fixed the problem
