Not enough heat on A3
 

Hi,

I do not have enough heat on 72 degrees SP and below 70 outside. I need to increase SP to 78 degrees to have a little more heat. Even, if I select HI temp. heat is deficient.

I have read all topics about this issue. I have already check coolant, flush heat core, VAG-COM only send a problem with inside/outside flap air (open or short)G113 but still works.

Any ideas?
