Audi A4 Problems

Oil Leaks From Camshaft Chain Tensioner and Valve Cover Gaskets

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

Ignition Coil, Ignition Wires, and Spark Plugs May Fail

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.

Rainwater May Accumulate in Plenum Tray Due to Clogged Drains

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.
