Heater not getting very hot
Posted: Wed Dec 18, 2019 12:35 pm
I had an issue where my coolant temp wasn't getting up to temperature and the heaters weren't getting hot at all either. Since then I replaced the inline thermostat (the one above the DSG box) which fixed the coolant temp issue so the needle now gets to 90. However although my heaters get warmer now, they dont't sem to get nice and hot even after the coolant is up to temp.
I've scanned the car and found the following codes which may be related, however I have no idea how or where to check this:
