Audi S4 Biturbo Buyer'S Manual Download Page 5

Cars with differing stamps do not indicate any sort of 
foul play, as it is conceivable that owners move from 
one area to another, or may even have had bad 
experiences with some dealerships. 
 

Recalls 

We touched briefly on factory recalls when we covered 
modifications.  At the time of printing, we could only 
find recalls pertaining to the following: 
 

1.  Intercooler hoses – early models weak 
2.  Dust caps on tie rod ends – early models weak 
3.  Vehicle with tiptronic transmission – Brake 

control valve 

 
Note that not all of these will apply to later vehicles. 

 

Successfully completed recalls are marked 

in the service history booklet and are 

stamped by the main dealer, usually with a 

code. 

 

Test Drive 

By now you’ve looked over the car you’ve found and 
are more than comfortable.  You just can’t wait much 
longer to get in and take it for a spin – but before you 
do – you need to check that you are sufficiently covered 
by your own or the owners insurance policy. 
 

 

Choose a route which emulates most driving types 

 
Before driving off, check the condition of the tyres, and 
check the fluid levels under the bonnet – oil, water, 
brake fluid, power steering and washer bottle.  Be aware 
of any unusual smells – burning, brake or clutch lining, 
fuel and the like, both before and after the test drive. 
 
Adjust your seat, headrest, mirrors and steering column 
to a position that suits you. 
 
Locate equipment such as lights, indicators, wipers, 
park brake, and emergency hazard light switches before 
you pull away. 
 
When switching on the ignition, check for any warning 
lights that stay on after the car is started.  Pay particular 

attention to lights including Airbag, Brakes and 
temperature. 
 

 

The understated lines of the S4 Saloon 

 

 
When you’re comfortable, take the car for a drive.  To 
test the car as best as possible, you’ll need at least five 
miles of road, including a fast section of motorway. 
 

Ideally you should insist on seeing the car 

when the engine is cold – if not on the first 

visit, then the next. 

 

Drive the car gently at first until the engine has warmed 
up. 
 

Transmission

 

Check the car in all gears – changes should be smooth 
and there should be no sign of crunch or stiffness on a 
good manual gearbox, with no signs of the clutch 
slipping or snatching. 
 
Turn off the radio and listen.  Listen for knocks and 
grinds, squeaks and thuds – If you hear any – start 
asking questions… 
 

The car should pull smoothly from all gears 

and is capable of pulling from 30mph in top 

gear without the need to change down a 

cog. 

 

A healthy car should cruise quietly and effortlessly.  
Push the throttle and you should feel an immense surge, 
and no loud sounds of air escaping from the intercooler 
or hoses, or whining from the transmission or driveline. 
 

Brakes 

Test the brakes – the car shouldn’t dive excessively or 
pull to either side, but remain composed through 
straights and bends, with a firm pedal feel.
