Audi A4 Problems
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.
