Re: Warranty on warranty repairs ?
Having worked in extended warranty..if we had paid for a new MAF under our warranty we would expect that part to carry a 12 month warranty, even if our warranty had expired. At worst the owner would be liable for labour in fitting it.
I don't see any difference in principal to this situation (though happily Alfa have sorted it..they are doing well recently, have you all noticed. Its others who seem to be letting Alfa down)
If a garage tried to blag me I'd just say that a substandard part had been fitted, and if they would not help replace it I'm sure a small claims court would.
