Thanks, yeah it's basically even on the highest setting lukewarm on the passenger side and almost cold on the drivers side. and if you have it on auto, on high it won't go over 2 bars of fan speed because the heat just isn't there.

I have an Octavia Greenline 3 (2014). A few years ago I had the dreaded mit silikat issue after the main water pump failed where Skoda claimed they flushed the system twice but cabin heating has never been the same since. I replaced the heater matrix in the glove box with surprisingly little residue in it. Recently had the following errors in VCDS 3 Faults Found: 18825 - Coolant Pump for Intercooler P023B 00 [10101111] - Short to GND P023A 00 [10101100] - Open Circuit Is there any way to tell which Aux water pump I need to order from these codes without physically looking at it? I understand there are two different types so don't want to order the wrong one. And is there any chance this might finally fix my cabin heating issue? VCDS.txt
