When I sold my S2 a couple of weeks ago, i made a list of ALL the things the car uses, then stuck it to the glovebox
IE...
the correct oil + service intervals
correct plugs for spec
Super unleaded ONLY
Tuners to use + numbers to phone for advice etc...
+ a few more bits and bats.
If they are not stuck to, the car will die soon IMO.
Probably see it on the trader next week for a grand

fooked
Oh well, im well chuffed with me Audi so fook it
