Disadvantages of the VW AUS engine
- The reason for floating engine speeds is most often the contamination of the throttle assembly.
- Here, antifreeze leaks from the thermostat and plastic tubes of the cooling system are not uncommon.

Hi there, I have VE Golf IV 1.6 16V (AUS) from 2000 and it suffers from antifreeze leaks and also burns engine oil (when I drive downhill with shifted gear and when i pull the throtle at the bottom end of the downhill, a lot of white smoke is getting from the exhaust). Does anyone have an experience with this? What could be the source of these? I read about potential leaking engine head sealing or damaged piston rings, what do you think is more likely?
