I have taken my car to the mechanic and he said it is going to cost around $1500 AUD to replace it. It sounds like a lot of money,so I wanted to see if someone has any idea if this price is acceptable or he is ripping me off.Come on, vebop, it's an Audi, so the answer is naturally going to be "a lot". Seriously, check with your nearest local stealer for an indicative cost. A quick check on Fleabay returns a part cost around the $380 mark (that's for OEM), but God knows what Audi will charge to supply and fit. A starting point, at any rate.
