G12+ or later, so Comma G40 is a choice from Halfords and usually buy 2 + 1 free.
The dealer will just give G13 by default now I think, as it is 'eco'. You have to warm (but not hot) the engine, turn all heater zones to HIGH until warm air comes out the vents. Remove coolant cap. Take off he belly pan, undo the spring clips on each rubber coolant pipe joint that runs beside bottom of engine/gearbox and pull apart. There is no drain **** (c o c k) in radiator when I looked. Leave to cool a bit to prevent thermal shock (or flush with hot tap water), flush with water until clear and refill with plain water. Run for a few minutes and drain again. Now fill with 50-66% of the cooling system capacity with neat coolant. Now top off with water and open the bleeders which are under the plastic cover next to the brake fluid reservoir IIRC. Run the engine with heaters on full, keep topping up with water and allow the air to escape through the two bleeders. Last edited by snapdragon; 18th June 2014 at 11:58 AM.

Depends on a few things such as A8 or A8L so best to check the online checker such as :
http://www.commaoil.com/products http://fuchs-eu.lubricantadvisor.com....aspx?Lang=eng For mine is Capacity 15,8 litre so I just put 10l of coolant in to give ~63% strength (VAG bottles say up to 66% on them) Last edited by snapdragon; 19th June 2014 at 01:59 PM.
