A mechanic friend ( who has been a mechanic for over 30 years) cut the wires to my mass air flow sensor because they were torn, and he had to botch up the job, because
A. He says he doesn't know where each color goes and says they aren't matching up with diagram and says wrong amount of wires and wrong color ( was 6 wires. He's looped 2 only reconnecting 4 and says other 2 don't matter ? )
B. He ran out of wire
In my opinion he should have not begun the job if he's finding it too hard to finish. I have an MOT coming up and I need the problem with my MAF sorted asap as it could fail emissions or stall during the test cos of the faulty wiring.
I've already replaced the actual MAF sensor, my friend did diagnostics again and its still reading open circuit on MAF sensor/wiring
I went to a auto electrics garage today and booked my car in on Wednesday, he said despite me having my friend do diagnostics he will have to do his own diagnostics to know for sure what he is working with ( which is fair enough ) and he said £25 for diagnostics,then £25 per hour for him to look at and repair my car.
So if I put £200 aside, will that be enough to cover the job do you think ?
It's £25 diagnostics so 7 hours (£25 per hour) say in worst case scenario would be £200, is this about right, £200 or less to fix maf sensor wiring fault ?
