I've now had a clear answer [thanks Siena] and can confirm the D3 4.2 petrol engines are indeed belt driven for anyone else that may need this information ;)

As already stated by someone though, you ain't never gonna know unless it's stripped apart. If it is and...
You got a quattro AWD?
I'm finding it really hard to fathom how the difference between wet and dry could cause such a problem as you describe and under the conditions you describe????
