Vehicle Model	Production Period	Capacity in Grams	Differing Features Of This Refrigerant Circuit
Audi A2	From 06.00 to 07.01	525 ⁺ / _- 25	Yellow colored restrictor Condenser with part no. 8Z0 260 401 (403) and index B or C
Audi A2	As of 07.01	500 ⁺ / _- 25	Red colored restrictor Condenser part number 8Z0 260 401 (403) with index D.

NOTE:

Replacement restrictors with different holes are available (yellow colored 1.54 mm, red colored 1.42 mm).

Depending on manufacturer, color of red restrictor may tend more towards orange.

To avoid altering the cooling output of the air conditioner, restrictors with the same hole diameter must only be installed.

A restrictor with a smaller hole (red colored) and a condenser with smaller internal volume were introduced as of model year 2002. The capacity has therefore been slightly modified (condenser -70 g, smaller restrictor +50 g). Refer to [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Description and Operation .
