"as with all things motor trade we cant be expected to know every system on every car"

Perhaps this is where you and i differ,i only work on a system if i understand it, how else would i know i,m repairing it and not making things worse.

Hi Kev
I understand your keenness to see an improvement in the way we go about diagnosing & repairing vehicles, but I don't think that it's quite as black & white as that me ole fruit.

I spend a lot of time learning how a system works & often this learning is done whilst trying to fix a fault. We all have to balance the Learning/Earning Ratio (LER ) & I try to make sure that the customer doesn’t pay too much for my inexperience with a particular fault.

If we were aerospace technicians, we would not be allowed to work on anything that we were not fully trained & equipped to do so. We would also have accurate test & service data to work with too. The motor trade is miles away from that level of professionalism though & I think we have to accept that it is impractical to expect everyone to be fully conversant with every technology that comes through the door.

In an ideal world there would be no head scratching, only methodical & structured test/repair routines. I am sure that if you are honest Kev (& I know you are), then you will admit that you don’t fully understand every system that you are tackling. Even the guys at the top of their game have to “learn as they go” at some point.

We are all “blagging it” to some degree, some just more than others!

Cheers all

Dave
