Hi All. The dreaded amber engine symbol popped up on Sunday. I'm just back from a Jaguar dealer who plugged in to find it was a fault with bank 2 oxygen sensor number 3. They have quoted me £675.17 inc vat for the part and fitting. I have no experience of this failing in any of my previous cars so am not sure if this is the going rate (appreciate labour will be more expensive at a Jag dealer), but wanted to know if anyone has had one replaced recently and this quote is in the right ball park. I have ALA warranty but the dealer won't deal with 3rd party warranty companies so I have to pay and try to claim back (hoping this is covered under the warranty). Any guidance much appreciated
