Make sure certain things are sorted on the car.
Such as if there is a lack of pwer (compared to another S4 you have driven) Get them to change the MAF sensor. (This doesnt show up under diagnostic check) and often you can tell by lack of power and bad mpg. Get car fault coded by someone you know or independant engineer. Also would be nice if the garage offered you some sort of warranty even 3 months.
Then you can get yourself down to MRC forr a healt check (
WWW.MRCTUNING.COM) This will tell you what is right or wrong with your car.
Also check forbad exhaust gas temp sensor, Get auxilary water pump checked, brakes discs and pads checked, and throttle body boot and hoses)
Saying all that, its best to get a later model S4. Such as a 1999.5 model which means after Julyish 1999. Those cars come with better ECU and is facelift model, Nicer lights amongst a few other improvements.
You can fit your system into it bu t i think you might need a specialbracket for it. If you want I can give you a number of a place in LEYTON called German city that does a lot of spares for Audi A4 cars.
The Mileage isnt that bad on the S plate but I think they could drop off a it more on price.
I picked up my first S4 in December and paid 10,000. It was a V reg facelift model, and had recaros,, sat nav,bose 6 speaker system, tv, metallic paint, one owner, motorway miles, even though it was a bit more mileage than yours (110,000).
I think £7,500 is reasonable for an S reg your spec. Prices have been coming down on S4's Ive noticed recently. Try do a search on Autotrader.
Ive seen an S reg for £5,600 on autotrader (saloon) and theres an avant for £7500.
If you wait around and check autotrader on thursdays, youll find just what youre looking for. be patient and your car will find you.
I also think headlight washers only pop up when used when driving over certain mph. Not sure though. Mine dont work either at standstill.
non working radio? What do you mean by not working. No radio code? or just plain mangled radio? Audi will sort it out for free if you have a code problem.
