Had this all typed out, went to Submit it and lost the whole text I had written so will have a go again!
Went back for a second look this evening at it with my VAG-COM and a few other tools, after a weekend of pulling out my hair (not that I have much of it!),searching in the forums here for all sorts of problems to look out for on buying one of these! Took a log of fault codes which I will post up here for someone to tell me whats going on (dont believe its too serious though any of them, or nothing that some of the other members here may not have come across before!) Dont believe theres al that much wrong with it but as was said somewhere before if you can see past the paintwork, then it cant be a bad car (like I said, paintwork will need a little TLC to restore it to its former glory and probably a little mechanical work too)
Have modified VIN no slightly to protect privacy for now...just in case!

Dont mind so much those ones in the Central Locking Module etc, had some of them before on the S4 so not too worried, probably only need clearing to see what comes back. Battery was replaced recently hence the Terminal 30 voltage error. Am sure one or 2 of you have had the Lambda sensor faults so dont regard this as being out of the ordinary. If anyone can shed light on the charge pressure positive deviation, then by all means do so or enlighten me as to what it could be! (surely positive deviation would be an indication of no leaks or else its overcompensating for a leak somewhere.)
Engine itself didnt seem to posess any nasty rattling noises etc., even went to the extreme of "listening" to the heads with a solid bar to see if I could hear anything but there was nothing out of the ordinary. Did notice a kind of "well greased chain running on sprockets" sound (best I can describe it!) from the back of one of the heads, drivers side, was in that general area so couldnt pinpoint for sure but dont know whether it constitutes a cam chain problem or not.
Did seem to be a minute exhaust leak sound from the area under the engine towards the passenger side footwell area but putting it down to the original exhaust which may have a leak somewhere near the LH turbo, again I couldnt tell for sure what it was but thats what it sounded like to me.
Checked a few groups of measuring blocks with VAG-COM and paramters were in normal ranges at idle at least. Was some misfirings showing up on idle but went away as soon as being on part throttle...about 1000-1100 rpm or so. There is no fault codes for misfires and certainly no hesitation in it with throttle open on the road, so I'm sure it may be normal to have a small amount of it at idle? (Did do this on my S4 aswell but never took any notice)
Overall I think these are minor things that wouldnt take alot to get rectified, someone just needs to spend a little time on it orting these few bits and pieces out. Come from a decent mechanical background working in the Ag. industry and having worked in the CHP generation industry for a short while, I mean I dont know alot about RS4's inside out but am sure I'd have enough to be able to walk away from one if I saw or heard something dodgy. Obviously there are a few experts out there and some have learned the hard way!
I'm probably mad and/or daft as I've put a small deposit on it which I dont mind losing should someone tell me something that will turn me off it entirely or there is someting quintessential that I have overlooked on both viewings, so unless something spooks me in the meantime, will be picking it up Friday. Did "feel" this is the right one after a good while looking for something suitable.
Like those of us out there that are buying/owning one of these, theres always an element of paranoia of something going wong but this is inevitable with all cars at least, these ones are there to be enjoyed! Just waiting for the day sooner or later I can put a

on my face!
@Contigo, car is located in Bromley, not too far in the A21 off the M25 but was easier for me go in via A20, almost same difference from the Dartford Bridge/Tunnel. Second opinion would be great but I've probably gone a step too far at the moment but if you still would like to have a look, let me know.
@rtd, yes think the car was for sale back in '06 at around £23k according to current owner, previous owner to him was located in Worksop. Car doesnt have too much mileage put on it in the last 2 and half years or so it seems. Was PDI'd in Germany before it arrived in the UK, don't know if its like this for them all??
Sorry for the essay but trying to give an honest opinion of what I though of the car, of course all comments and suggestions or other info and advice would be most welcome before I do decide to go ahead and complete the purchase!
Thanks for reading!
Tom
