Let's not get distracted by all that rubbish.
Let's focus on the task at hand.

The map has shown a weakness with the car. This is evident with it being returned to standard and still having the problem.

Unfortunately this is the nature of a map.. They put more strain on parts and they do give up easier.

Get it round to someone with dice/vida to read the code & tell us what codes are being displayed. Then we will have a better look at what the issue may be.
