2004 Audi A4 Problems

Engine Misfire Due to Failed Ignition Coil, Spark Plug, or Ignition Wire

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.

Engine Oil Leaks

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

Various Probelms Caused by Clogged Plenum Tray Drain

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.
