I just bought a late 2000 facelift S3. Looking through the service history I can see it had a new cambelt kit and camshaft adjuster fitted at 65000 miles. All well and good, but it looks like they didn't do the water pump at the same time. The car is now up to 84000 miles and I was wondering if I should think about getting this changed, or just wait for it to go and then replace it? What do you guys think?
