Jim here it goes:
1.- Check al four windows for operation from driver door and individual doors, both 
directions. 
2.- Check rear lateral view mirros from passanger door
3.- Check central loking systems al doors with release from front passanger and driver 
doors respectively.
4.- Open trunk.. check for interior light, evidence of water/rust under carpet, 
availability of tools, spare (small)  and jack (special Audi)
5.- In trunk check for condition of rear speakers and/or presence of CD/Amplifier.
6.- Turn radio on (ignition off) check operation of automatic antenna (up down at least 
5 cycles)
7.- Open hood bring hood down to 5 inches from closed position, release without pushing 
or throwing. Hood should latch both sides.
8. - Reopen hood visually check driver side of block for presence of oil. Check surface 
of area where car normally parks ( home garage, dealer lot ) for evidence of drips, 
spills or other indications of fluid leaks.
9.- Visually check levels of fluids in following reservoirs.
Winshield washers, Hydraulic systems -this one is very important -(brake/power steering 
( pentosin is fluid )), brakes (brake fliud), engine coolant. 
10.- Check condition and flexibity of all possible hoses big, long , short and small. 
Specially critical are turbo to intercooler and intercooler to intake manifold.
Hoses related to PVC systems should not be flat or mushy.
11.- Check visually all electrical connectors for presence of metal retaining clip.
12.- Carefully check for cracks with hand contact all visible & reachable rubber boots, 
special attention to steering rack and CV joints.
13.- Request info and data on timing belt and water pump replacement. date & mileage.
14.- Data on brake rotors, calipers/pads. Purging/flushing of brake fluid.
15.- Under car (suggest strongly to inspect)
Presence of oil around turbo specially in the piping to an from oil cooler. Likewise for 
water hoses for turbo cooling ( turbo fuctioning to be checked later)
16.- Complete the hand and visual inspection of CV joint boots (inner and outer)  
17.- Using trouble light inspect for oil leaks the front and rear parts of crankcase for 
main bearing seals condition.
18.- Visually inspect exterior of center muffler, cathalytic converter, rear resonator 
and all hanging points including rubber hangers.
19.- Check each wheel individually for visible condition of rotor, brake cylinder, 
caliper and thickness of pads. Special attention to condition of electrical connectors 
for pad wear and ABS sensing.
20.- Get into driver seat...
Do not start engine !
21.- Turn ignition on check for OK readout display of Autocheck system.
Place computer selector to read boost pressure (bar) and check for 0.9 bar read out.
Check for following lights to be on:
Engine check small engine and Anti lock brakes in yellow
Batt,Seat Belt in Read
Apply emergency brake to lock Red light shoud come on (Brake)
Open doors sequentially door light should come on (red)
When opening driver door with ignition key in lock beeping alarm should sound
22.- Place sustained pressure to brake pedal hold and ...
22.- Start engine check for oil pressure light coming on and turning off in less than 
two seconds, brake pedal should give slightly as hydraulic pressure reaches booster 
cylinder (good signal).
23.- Check idle speed with climate control in economy position at least 800 to 850 RPM's
24.- Slowly rotate steering to full lock left and full lock right, hold position at full 
lock for 20 seconds, pump brake pedal rapidly for 6 or 7 times and hold, check for auto 
check system (brake) light blinking if not... very good... release eveything...
25.- Slowly depress accelerator pedal until 3000 rpm is reached release suddenly check 
for delayed decay of RPM's to 800 (slower that return of pedal)
26.- Allow engine to idle, set air aconditioner temperature to 75 and to AUTO, listen 
for clicking noise from compressor clutch energizing set back to ECON and back to Auto 3 
or 4 times, idle speed should remain fairly steady ( good)
27.- Operate sun roof as follows (assume roof is closed)
Prees forward side of switch and HOLD, roof should open at an angle and stop. release 
switch.
Press back side of switch and hold, roof shoul close and STOP. release switch .  
Press back side of switch and hold... roof should travel to back to fully open and stop 
without any loud clicking noise. It did good . release switch.
Press forward side of switch and HOLD... roof should fully close without stopping and 
without continuing to open position. Release switch.
Do not over exercise sun roof without adequate lubrication !!! just test it 2 times.
28 .- Engage reverse gear and slowly very slowly release clutch and brake pedals ( 
objective is to move car about 2 or 3 inches ( do not rev engine more than 1200 rpm's)
Have girlfriend from outside of car observe forward tires for vibration ( visible and 
noticeable ) while clutch pedal is released and tires try to move 2 to 3 inches.
If wheels vibrate clutch remedies in the future may be necessary.
It is also possible that a caliper or calipers are sticking ( not to bad to fix )
29.- Switch on board computer to MPG reading, read out should be:
21.o to 23.0 if driving in city all time with air cond on
23.0 to 25.0 combined city and some road highway driving.
25.0 to 28.0 Mostly highway with air
28.0 to 31.5 all highway w/o air and properly tuned ( maybe a little lean) oxigen sensor 
crying in despair.
Above readings assume car not overloaded and inflation pressure OK.
The following tests should be conducted with seat belt on and on an isolated road 
preferqably with some  elegant turns....
Brakes and ABS testing 
Purpose is to evaluate ABS and brake boost interaction. Brake booster pressure must be 
able to stop wheels to lock.... ABS should read potential lock before it occurs and 
force return of brake fluid  on the particular wheel.....
Accelerate car to 45 to 50 MPH ( check for absence of vehicles behind ) abruptly I mean 
abruptly depress and hold brake pedal until car comes to stop... foot on brake pedal 
should feel strong vibrations from the pulsationg ABS pump.... do not be scared it is 
working.... Park the car and inspect tracks on the road there should be no signs of 
SUSTAINED) lock on any wheel . Next test car may skid lateraly ( if it starts skidding  
release brake at once )Restart car back to 35 MPH depress ABS switch in 
dashboard...yellow light comes on ... abruptly press brake all or some wheels should 
lock car may skid lateraly. Good we got good hydraulic pressure.

Jim I will stop here, perhaps I have gone to far and too long Sorry
Best regards
