Another thing to mention is that cold metal parts are getting smaller as the temp decreases, shortening the pitches of various gears, including the gears of gas-distributing mechanism etc. Which may cause belt slipping and shot the whole mechanism.

On a second thought, implementing a key into the car for distant starts is not safe and would lead to severe problems with the insurance company if the worst case happens.

My decision is Webasto+AGM battery.

It will give enough heat to warm up the oil and metal parts (though it warms coolant mostly but I guess it would be enough to heat other engine components as well).

.. all of which still bounds me to inspect CVV tubes and oil separator regularly.


Car would be in place in 10 days, so I will post my experience here a bit later on.
