Hi just wondering if anyone knows what the part Number is for a replacment remote key fob for our 2003 A4 20l fsi .We purchased if from a repo co and only got the one basic key.Main dealers prices in the U.K are a joke (about $280usd) and there are so many to choose from on ebay. Also do you know where i can get a new cam sensor as it's showing on my obdII tester (again dealers prices are as long as my phone number). We'er new to audi and love the car it makes a great change to the usual crap i drive.Thanks for any help ,Darren.
