NOTE:

Production was gradually switched as of calendar week 45, 1998 (initially for Audi A6 with 6-cylinder diesel engine) to a condenser with smaller flat pipes.

Observe part number on condenser replacement (sometimes the only distinguishing feature).

Condensers -A- with flat pipe dimensions -B- = 20 mm and -C- = 3.0 mm must be filled with more refrigerant than condensers -D- with flat pipe dimensions -E- = 18 mm or 16 mm and -F- = 1.7 mm.

If condenser is replaced, observe flat pipe dimensions. If a condenser with different dimensions is installed, the sticker -A- specifying the capacity for refrigerant R134a is also to be replaced, or the old capacity specification is to be removed and the new capacity is to be noted, for example, using a waterproof marker.
