now all the oil leak problems have been sorted the 8 has decided to break something else........symtoms are a lumpy feel when at idle at apparent even worse fuel consumption. Managed to get it on vagcom and have a misfire on cylinders 2 & 4 and intermittant fault with the water temp sensor - this explains the engine management warning light coming on and off all the time.

.............so basically its running as a V6 at the moment!
Dreams of a masser are looking dim if I continue to heamorage money at this rate! I am desparately hoping this will be the last of the repairs for at least a few months and dreaming of the day its running properly with no problems as all I'm getting from the missus is "I said you shouldn't have bought it...blah, blah" (which I'm struggling to argue with at the moment quite frankly!)
Based on my experinces with local garages so far anyone fancy taking a guess at the part/labour prices I have been quoted? Starter for 10......main dealer has said £36.58 for the sensor and £56 for each coli + 2 hours labour. I can get the parts on-line for half the price @ Ignition Car parts but wondered 1) is this a good idea or should I go with the OEM parts? and 2) How easy a job is this to do - i.e. could I tackle myslef with a basic tool kit?
