No codes that's ment to say I've check basically everything I can think of and everything is acting normal testing cars coming back to me on Tuesday I can then give the vin number and some more details

Unfortunately with a fault that only occurs after a few days of driving and no codes set (though there must be a record of that in there somewhere have you looked at both OBD2 and manufacturer?) there is no real way to diagnose the issue unless you can re-create it at will. If you can't it needs to be driven until it is more broken or you are just wasting your customer's money - who will not be happy when you bill them for 4 hrs of diag with no result.
Anything else would just be guessing.

I have explained this to the customer but he wants us to look anyway I've told him I'll have to drive the vehicle until the fault occurs was just wishfully hoping someone had come across this same issue
