Time to service the Skoda. Here is the air filter after 10,000 miles and the new one on the left.
And if you thought that was bad, or not then the cabin filter is blacker. Must be working then. I'd show you the oil filter but that is just jet black. A change of feul filter caused some restarting issue and then the coolant was changed so that the car can cope with -27deg C. All done then.
