Hi all please help! SKODA OCTAVIA 1.5 TSI 2018

Interior heater blowing cold driver side and on off hot passenger side, has anyone done a heater Matrix Flush/Full coolant Flush and does it actually work?? Because New Matrix + Labour is approx £600 😵

Is a Flush worth a try??

I can't seem to see any silica bag in my Tank, maybe its there and maybe its split open not sure. What yall saying?

Kind Regards

To be honest the biggest faff with heater matrix is draining the coolant and then if you flushed it, disconnecting pipes, might as well bite the bullet and replace, not sure flushing would be that effective (I replaced mine).

Lots of blocked matrix threads going on!

Yeah, I think the main work is the refill procedure and pipe connections.

I think the actual matrix is fairly easy to access

Hi. Are you sure the cause is the heater matrix and not the climatronics passenger side flapmotor that controls the hot and cold airflow. In LHD vehicles its V159 i think.

These flapmotors are known to fail when they age, the potentiometer inside fails or the plastic stop breaks so that the motor loses its position signal.

Have you read DTCs?

Also do you have G13 coolant and does it read in your expansion bottle "Mit silikat"?
