1999 Audi A6 Problems
Check Engine Light Due to Faulty Torque Converter
A problem with the torque converter can cause the Check Engine Light to illuminate.
Digital Display on Instrument Cluster May Fail
The digital display portion of the instrument cluster may fail. Our technicians tell us the entire instrument cluster will need to be replaced to correct this concern.
Multi-Link Suspension Components May Wear Prematurely
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.
Inspect CV Boots and Joints at Each Service
Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.
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.
ABS Light Due to Control Module Failure
The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.
Water From Clogged Sun Roof Drains May Damage Control Modules
Clogged sunroof drains can allow water to enter the interior and accumulate under the carpet where various control modules are mounted. Over time, the accumulated moisture can damage the control modules.
Inspection of Water Pump and Timing Belt
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.
Maintain Fuel Quality to Avoid Misfires and CEL Illumination
Fuel quality must be maintained to avoid engine misfire problems; the misfires may cause the Check Engine Light to illuminate.
Engine Oil leak From Valley Pan Gasket and/or Head Gasket
An External oil leak may develop from the valley pan gasket (under the intake manifold) and/or the head gasket.
