One Alfa service center and two electrical service shops could not find or fix the problem even though it was so simple as to just pop-in a new switich, idiots!
I can better that for a tale of complete ineptitude from an Alfa Dealer .
Some time ago I bought a 164 Super Lusso on a P plate ,fantastic car ,only about 70K on it ,nearly unmarked in Proteo Red ,it had been really well looked after .The only problem with it was the fact that the cambelt had snapped .....
The owner was on holiday in Devon and in Exeter the car broke down in traffic and just would not start .The car was recovered to the local Alfa dealer and they investigated and diagnosed the belt failure and quoted a figure of between £3k-£4k to fix .The owner thought better of it and scrapped the car(Dismantlers next to dealer ,fortunately).
I saw it in the corner of the breakers yard and gave them £400 and they delivered it to my home the next day.
I had a good look round it ,poked around the engine bay and forced the top cover back enough to see the belt sitting there ,nice and tight ,no slack at all.I thought bugger it ,if it has broken this cant do any more damage and got in and tried to start it .Lo and behold it started instantly ,it wasn't noisy or anything ,took it for a drive and it was a real peach of a car.......MOT'd it later that day.
I dont know how on earth the Main Dealer mis-diagnosed it so badly - I even wondered if the previous owner had a case against them for negligence and could have sued them for the value of the car ( this was a good seven years ago ,when a 164 was worth something!) It is certainly the biggest story of incompetence I've come across .
