Matrix44

Hi steve, i flushed the heater with water for about 10min, there a lot of dirt comming out the heater, you can see on picture, so after 10min it comming clear water from heater, and connect everything and thats fix the problem, now i have hot air on passenger side also, so that fixed the problem thanks a lot.

Thanks Steve i will try flush it, is it possible to change matrix from passenger side like on old audi A6 c6?

Hi everyone, i have also problem like yours, have Audi A6 4g 2013, drivers side is hot, and passenger side blowing cold air, i have done diagnostic, no error codes, i dissasembly and clean water electromagnetic valve under the windscreen and did not fix problem, you think that matrix is clogged? So one matrix is feeding both sides?
