It also suffers from an occasional judder under load and never seems to throw out any soot which makes me think under fuelling, and if it is over cooling then the engine won't be running at it's optimum. Could be the thermostat stuck open. Fan works fine but rarely kicks in, heaters blow hot and doesn't loose coolant.
I can't really comment on the performance as it's bound to feel slow compared to my 16v Jetta but it does do 750-800 to a tank, pretty much all motorway between 80-90mph.
Any thoughts appreciated.
