water pump, timing belt, tensioner, roller and thermostat replacement: $1100

Do you talking about a cylinder head job or just a regular maintanance job? For cylinder head job it is a fair price with all these parts. If only timing belt service it is too high price.

Price would be right for here in California. Call another repair shop that has knowledge of repairing VW/Audi cars in your areaand get a quote from them to confirm.
