Ok, I can't seem to get definitive answers when searching. I see references to Mk7's having an automatic supplementary heating system for the passenger climate controls where if the A/C is on, that turns on the supplemental heating system before the motor/coolant is fully warmed up.
Anyone know what type of system it is? Is it all electrical? Does it burn fuel for the heat? Is it a heat exchanger setup tied in with the exhaust system?
I see references to Mk7's having a system that uses a heat exchanger in the exhaust system to provide this supplementary heat, and I also see people talking about how it burns diesel fuel to generate the heat, and I also see people say it's simply an electrical heater (think space heater) that is in-line with the normal coolant/heat exchanger system.
I ask because with my Mk7 G-TDI-SW, I smell a bit more exhaust when I turn on the heater with a cool engine, even when underway. It's not strong, but it seems to go away as the motor warms up.
