Capacities For AUDI R8 (42_) From My 2008

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. However, it is still accessible from the selected car via links, so may be relevant.

Features of the refrigerant system:

Red colored restrictor.
Reservoir
Two condensers switched in sequence
"Denso" A/C compressor with A/C Compressor Regulator Valve -N280-. Refer to [For engine(s) CTUA, CEUC, CRDB, CGXB, CPNB] System Overview - Refrigerant Circuit (vehicle-specific repair information).

Vehicle model	Production period	Capacity in grams	Differing features of this refrigerant circuit
Audi R8	From 03/2007 to 11/2012	680 ⁺ / _- 20 Originally these vehicles were filled with 650 g of refrigerant, then the capacity was raised to 680 g (see notes).	Red colored restrictor
-	From 11/2012	680 ⁺ / _- 20	-

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, red colored restrictors must only be installed.

From the vehicle identification number 429 DN 000751 (time period of production from 11/2013) the refrigerant quantity for the refrigerant circuit was raised from 650 g to 680 g and the refrigerant oil quantity was raised from 150 ccm to 200 ccm. The increased refrigerant and refrigerant oil capacity applies retroactively to all vehicles. On vehicles that were built up to the specified vehicle identification number, check whether the refrigerant oil capacity was already topped up during a previous workshop visit. If not, fill the refrigerant circuit with an additional 50 ccm of refrigerant oil. Finally, check the refrigerant capacity information on the information label and if necessary, attach a new information label with the correct capacity and language (for example, the identification label with the part number 420 010 535 and the index BA with the labeling in German and English). Refer to Commercial Names and Designations (vehicle-specific repair information). If there is no information label available with the correct capacity and language, amend the capacity information on the existing information label accordingly using a waterproof marker. Finally, increase the refrigerant oil quantity in the refrigerant circuit by 50 ccm if necessary and fill the refrigerant circuit with the above-specified refrigerant amount.
