Hi,
I thought I had permanently fixed a slow cabin heat issue by replacing the heater core in 2020 but the same problem is back again. My car was post-warranty and I somehow managed to get VW Canada to pay for half the repair since the problem had started during year 4. The engine temp goes up to half as expected after a few minutes (a little longer in very cold temp) but all I got was lukewarm air. The new heater core fixed the problem but now 3 yrs later the same issue is back. I have access to an Obd11 reader and would like to know what data to look for if that can indicate anything with a flap or sensor etc. Does coolant always flow through unsrestricted?
I also replaced a faulty water pump a few months ago. Coolant levels are still good.
Tnx.
