2009 Audi A4 Repair and Maintenance

Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.

2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.

Premature wear in various multi-link suspension components can cause noises that are difficult to diagnose. Worn suspension parts can also cause uneven tire wear and create steering alignment problems.

The car has just a bit over 100k miles on it, clean record and no accidents. This would be my first Audi to own if I were to buy it, so I don't have enough info about it. Any advise on buying this car, engine performance, reliability and maintenance. I was wondering what will I be looking for...
