I can't really say anything Ebbo I was a tech at the dealer and I don't put mistakes to bad mechanics I put it down to being rushed and pushed by the "system!" and a bad working environment
When I was there There was no training, No Backup, dropped in at the deep end and had to work to BMW schedules My body was theirs between half 8 and half 5 I ended up going to counselling because I let them get to my mind! (<-- Wish I'd Known Att back then He'd have kept me right

)
Basically the work environment of a dealer workshop requires someone who is an automaton! Fix A and B as per service sheet But do no more or you will have yer balls cut off
My problem was being too conscientious and cleaning hand marks off with a quick wash of the bike during the test ride up the yard So that it was clean and pristine for owners coming back
Dear lord How Dare I interrupt the busy schedule to report a broken bolt (usually corrosion on a head guard bolt) Or that the calliper was caked with salt and that it really would be safer for the owner/rider to have them cleaned out!
They were not interested in the Workers or even what is worse neither were they interested in their Clients, only in their money!! All they were interested in was the bottom line and getting stuff in and out of the workshop And What if it was a bit stuck or dirty? That Didn't matter! If you were on a job and someone came in you got pulled off the job and were dragged to look at something I hadn;t the intelligence back then to tell them to "Fuck Off" I was busy!!! I was too worried about keeping my Job!
For the first 6 months I provided my own safety boots use my own bike gear for road testing even had to supply My own overalls and when we moved the the new premises the wanker in charge asked me not to wear my Scania overalls?? Yet he had plenty of time to organise dealer ones up till then Dealer ones thats a laugh my Scania ones were and Are ten times the schite they provided me!! I haven't crossed the door since I walked out back in August 2004
I'm still friendly with a few of the guys that are still there! but I have NO respect at all for that money grabbing slimey Fuckwit running the place! I wouldn;t cross the road to piss on him if he was on fire! That bastard nearly put me in a mental asylum instead of sitting down with me and having a "chat" and finding out what the problems were
Sorry Blood Boiling Apologies for the Rant But Damn it felt good!
