2005 Volkswagen Passat TDI
Check Engine Light Due to Faulty Torque Converter
A problem with the torque converter can cause the Check Engine Light to illuminate.
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.
Check Engine Light Due to Issues With Glow Plugs/Wiring Harness
Because of issues with the glow plugs and/or the glow plug wiring harness from the control relay, the Check Engine Light may illuminate. Our technicians tell us there is a service bulletin, not a recall from Volkswagen regarding replacement of the glow plugs on 2004-2005 model years only.
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.
Flasher Relay Failure Can Cause Erratic Turn Signal Operation
Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
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.
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.
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.
Engine Oil Leaks
Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.
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.
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.
Odor from HVAC vents
Condensation may develop in the heater case which can cause a musty odor from the heating, ventilation and AC (HVAC) system. Our technicians tell us a cleaner is available for the heater case. Also, the drain system should be checked for debris.
