MK2 Toledo Auxiliary Heater and Cabin Temp

No aux heater far as I know but my car warms up much quicker (I presume yours is diesel ? )
They can be slow to warm up , a new thermostat might help if your one is showing its age now and taking longer than usual To warm up

Longer warm up times are normal in the winter, even more with diesels since they’re more efficient putting less waste heat into the cooling system and the engine block is thicker taking longer to warm up. If the thermostat hasn’t been replaced it would be worth doing. It’s job is stopping the coolant flow into the radiator until the coolant has warmed up. As they start to fail the coolant flows past even when cold increasing the warm up time.

I had the thermostat replaced in my 03 Leon TDI and that has helped. But it can still take around ten minutes to get warm when its below zero outside. I also have a petrol Mazda and that starts blowing warm air within five minutes but also uses a lot more fuel. More modern cars often have heated seats to help during the warm up. I do remember reading that some cars have an extra glow plug that warms the coolant when the car is first started. There are also aftermarket block heaters that use an electric heater in the coolant system. These are plugged into the mains overnight and more common in the countries that are a lot colder than the UK.

Sorry bud but no aux heater
