modern garages tend to rush jobs in/out quick as they can to get more jobs booked each day, these i find are the larger dealerships like reg vardy who couldnt actually give a **** about the customer excpet there money (the bosses, not the technicians). so problem jobs that need a level of diagnostics can take a chunk of time out of 1 guys days bookings , so these jobs are "not welcome", as they cant re-coup the time spent to money lost ratio, and the technician is told to "plug it in, see what it says, cancel the error and well tell em to try it", then is given a large service to do which makes money for the firm. I know of a small family type run dealer that understands this and has no problem leaving a technician for whatever time is needed to diagnose a fault correctly, in turn it has had many customers from other dealers in the surrounding area who have been "let down" by there usual dealer goto them, get the problems sorted and now use them as there main garage for servicing e.c.t., so a few hours lost in diagnostics 1 day can lead to a new customer, plus that customers friends and family another day for general servicing needs. (yes they do charge for diagnostics, but if a job takes 6 hours to diagnose they charge 1-2 hours labour rate on it, another point is their labour rate is almost half that of a large dealer rates)
as stated before, these days its not as simple as plugging a computer in and instantly getting the fault diagnosed, the fiat examiner is as some1 correctly stated "just a tool", however in the right hands and with all the added plug-ins and add ons that are available for it its a very powerful tool. its just unfortunate that theres still alot of ppl in fiat dealerships that havnt got passed the "cancel the error" stage in its functions.
i spent 3 hours training 2 guys on some of the functions of the examiner and some of the equipment that goes with it, at the end of it they simply said "we only need it to cancel air-bag errors", maybe i should post the dealer they work at so you guys can avoid it!!
