Dont I repeat dont bring it to a dealership. If you are going to do it yourself get onto the 147 Forum and they will tell you all you need to know.
Its a bit unfair to diss Dealerships. Whilst I agree that they may not all be as helpful as they could be, some independant 'experts' can be just as unhelpful.
I've been involved with Fiat/Alfa/Lancia for over 30 years and try to do the best we can. I know both Gerry Campbell and Don Baker personally and would vouch for both of them, regarless of the fact that they both came from Dealerships themselves. In fact they have on occasion, come to me, a non mechanic for advice.
The Alfa/Fiat network in Ireland is quite small, and most people know each other quite well.
Both Gerry and Don, use dealerships, for parts, and for information, and the favours are equally returned.
Remember, the Dealership you disrespect, could be the one who is supplying your parts and service (tools etc).
