05 What is VWs part numbering scheme?

A: Each part number is composed of nine numbers in three groups, followed
optionally with a letter suffix (taken from WolfSport's catalog):

vvv ggg ppp [s]

   vvv:  Vehicle type      ggg:     PRIMARY INDEX
   171 = R/G I             100-199 = Engine/Cooling/Clutch
   161 = Jetta I           200-299 = Exhaust, Fuel Tank
   165 = Jetta II          300-399 = Transmission/Transaxle
   261 = 16V GTI           400-499 = Front Axle/Suspension
   531 = Scirocco I        500-599 = Rear Axle
   535 = Scirocco II       600-699 = Brake
   155 = Convertible       700-799 = Cables, Bumpers and Foot control
   191 = Golf              800-899 = Body/Interior
                           900-999 = Electrical, ignition, fuel injection

ppp: Individual Part Number s: Suffix, optional

The primary index and the part number are the most important numbers
because many of the cars share the same parts. So do not be surprised to
see a 171-Rabbit type part in a Jetta.
Note that some part numbers are exclusively related to certain parts
of the car. For example, vvv = 020 are related to the transmission,
vvv = 056 common oil filter.

Note: This is scheme has been in use since the Beetle days (111 - Standard
Beetle - LHD) but I leave that for the [A] FAQ. AUDI uses the same scheme
as well (?).

CHEMICALS

NOTE:
This section lists some of the more useful chemicals to use on cars.
Be aware that many of these chemicals are harmful if used improperly and
could result in stripped paint, rubber becoming brittle, up to poisoning,
cancer and death.
Dispose of them environmentally!
