Hello, I recently purchased a used 2008 S5 4.2 V8 and noticed that the coolant reservoir had a small crack in it and I want to replace it but I cant find a used one OR a part number for the life of me and I've tried everywhere online. If someone could point me in the direction of finding a replacement it would be greatly appreciated!

There is a vin split for an 08, but either one is 70.68 and either in stock with us or we can order it from Audi taking 2-3 days to get here first. Plus shipping of 11-15 dollars approx, and 3-5 days to get to you once it leaves us. For up to 03/08 it is part number 8K0-121-405-M is the newest number, and from 03/08 it is 8K0-121-405-N for the newest number. There is a smaller hose that connects to the tank and it's different depending on the vin number also. It must have something to do with the location of where that line connects to the tank that determines the correct p/n for the one you'd need.
