I work for FIAT/ ALFA ROMEO in kingston, CURRIE MOTORS, its been a FIAT dealer for a year now, as well as a ALFA agent.
Although all technicians go on the courses provided by FIAT, they are just knowledge/ training on systems that are found on current vehicles- they dont train you on ' how not to be a idiot '.
Dealers are now required to have ALL their technicians registered by the IMI, so that not just anyone can work on your car- but it will take time to assess all tech's and give them a grade, Level 1, 2, or 3.
At the end of courses, you go back to work with knowledge gained, but the process of 'how your dealer works' varies between franchises- and this is where the difference is felt.
Dealers are allowed to run their franchise however they want, as long as they meet certain standards/targets set by FIAT, and i have seen franchises taken away if dealers are failing.
At my particular dealer, we have 3x FIAT/ALFA tech's, 1 of which is a DET, we also have 3x others who were ex-toyota/nissan etc.
Time has to be taken to train all of us, but to get the toyota guys up to speed on systems like selespeed, 'cos toyota etc dont have this, and when something new comes out i.e 4x4 panda, the cars are released way before any training is available, so if a problem arises, you have to do the best you can with what you got, the DET can help you if a tech gets stuck, but your still expected to produce certain hours a week, as well as get the job fixed right first time, which can take you 2 hours to diagnose, 2 hours to fit, and you get 1.5hrs paid for.
I understand that there are morons in dealerships, but with the IMI register coming into effect, things can only get better.
