Engine number identification

SOURCE: engine number location for 2002 audi a4

is it a 1.8 turbo or 2.8 V6 or 2.7 biturbo V6 ? on most models what you will be looking for is a 3 letter code like ATQ or APW and is normally on a sticker on the timing belt cover, it is also stamped into the engine on a ledge up high. if no luck there check the owners manual, around the 3rd page there will be a sticker that was put in the book during predelivery inspection this sticker is about 3 inches by 3 inches and filled with id codes for almost everything. If the pdi wasn't done right another copy of the same sticker will be under or next to the spare tire in the spare tire well.
