My back-alley guy is $100/hr, bmw dealer... not sure but it should be around there too... I have heard way too many horror stories regarding reapairs at the dealer, specifically unnecesary repairs etc. and there's when they rack up hours/parts and your bill keeps growing.
Bottom line: avoid dealer whenever possible, and I can say the forum peeps concur unanimously!
In the other hand, you have better and way more dedicated professional service all around Europe. 110 euros is a bit steep for my taste, I'm sure there's plenty of knowlegdeable mechanics in your area too.
