An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.

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.
Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.
The water pump may fail resulting in engine overheating and possible timing belt damage. Overheating and/or timing belt failure can result in very expensive engine repairs. As a precaution, it is recommended to inspect the timing belt and water pump at regular intervals.
Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.

2001 Audi A4 Reviews
Works great under warranty, but very expensive to repair. Mine is 8 years old and I am no longer seeing value in repairing it as I could buy a new car for what it has cost me to repair it recently. Mostly wear and tear items. But for several years I was having to repair cam engine valves (?maybe?) where the engine was leaking oil. Not a cheap repair and it happened 4 times (twice was under the 1 yr parts/labor warranty from the previous repair).
