I also agree that selling parts kits is a good idea so you have everything there needed to do the job properly.

A few years back I was working at a Seat dealer as a reporting technician (basically chief technician) and on those and most other VAG cars there are certain bolts, pipes and gaskets etc that need to be replaced when doing certain jobs. A lot of the bolts are stretch bolts so it's obvious they need to be changed. The other technicians never bothered ordering all the bits they needed so just refitted the old stuff which IMO is poor practice especially as we were dealing with new cars that are under warranty.

I got the hump in the end with getting other techs work and not having the bits to do it so ended up compiling parts lists for the partsman to refer to and build a kit so to speak when we had a certain job to order parts for.

The other techs still never bothered to fit the new parts which I think is piss poor tbh. Takes just as much effort to refit the old shit as it does to fit the new stuff!

Probably explains why I hardly ever had many comebacks I guess.

We had an Alhambra come back once after a cambelt with a broken block where the tech reused the old bolts, 2 sheared and the other remaining bolt took the strain and ending breaking the threaded part of the block off!!
