I bought this vehicle at drivetime in pittsburgh (north hills) with 36,000 miles. The engine had a loud sound from the moment that I took it off the lot. I was told "that is how vws sound". Progressively it has got worse, now I have an estimate to replace a timing chain and camshaft with only 82,987 miles. This is insane. It has always been bad, and I am furious.
