2005 Volkswagen Jetta TDI Problems
RepairPal has identified the most common problems with the 2005 Volkswagen Jetta TDI based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.
Oil and carbon tend to build up, creating restrictions in the intake manifold. Symptoms will be loss of power (sometimes severe) and poor fuel economy.
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.
The driver door wiring loom cracks and degrades with time due to weathering and frequent opening and closing of the door. This problem affects the normal operation of all electronic components of the door including, but not limited to:
-Electric Door Locks
-Fuel Filler Door Release
-Interior Lights Stay On at All Times
-Power Side Mirrors
The correction for this issue is to replace the driver side door wiring harness. For security purposes, the doors can be locked with the key. The interior lights should be shut of manually, and through the multi function display in the gauge cluster to prevent battery drain.
The 2.0L TDI engine used in the Volkswagen Jetta TDI very commonly faces camshaft lobe wear issues causing:
-Pronounced loss of power
-Backfire through the intake (heard under the hood)
-Rough vibrations while the engine is running
-decreased fuel economy
Correction for this issue requires substantial internal engine work including replacement of the camshaft, hydraulic lifters, and possibly fuel injectors
To help avoid this issue, ensure you are using the correct oil for your engine, as listed in your owners manual.
Electrical issues that are difficult to diagnose—and sometimes intermittent—are typically due to ground wiring issues. The most troublesome ground locations are under the battery or at the engine.
Condensation in the heater case may cause a musty odor from the heating, ventilation and AC (HVAC) system after sitting for two hours or more. Our technicians tell us that a cleaner is available for the heater case and the drain system should be checked for debris.
To ensure longevity of the engine, our technicians recommend to follow the maintenance schedule for the timing belt.
Cars using biofuel typically have problems with injection pump failures; symptoms can include a "no start" condition or external pump leaks.
Heater core leaks are common in this model, more so if the wrong anti-freeze/coolant is used in the cooling system.
One or more power windows may fail. Our technicians tell us this is commonly due to a failed window regulator which will require replacement.
Reverse gear failures and noise in the manual transmission models are common.
