Evening all,

Can anyone tell me how to flush the heater matrix on a 1996 A6 2.6 SE?

Alternatively, is there a way to un-block it and if so, does anyone have a step-by-step guide and maybe some pictures. I have no idea of the location of the heater matrix pipes but there is a cover at the rear of the engine that appears to hide what looks like the heater box but i'm not sure so if anyone knows that would be a great help.

I know I have to use a hosepipe to run water through to try to flush out any muck but where do I put the hose to start with.....and please, no crude suggestions!!



Thanks in advance
