Well, having sorted the coolant leak problem (see earlier posts) by way of a
new water pump there's another strange thing, although it's not a major
problem; the car starts from cold and idles with absoulutely no problem at
all. Next thing, if we turn the motor off and the restart after a short
while then it won't idle at all - dies every time; other than this, the
engine runs perfectly....
There's no sign of a misfire and the engine sounds as good as any 5-cyl Audi
I've ever heard.
