The red flashing light on the radio of a 2002 Volkswagen Jetta TDI typically indicates that the vehicle's anti-theft system is activated. This light serves as a visual deterrent against theft, signaling that the car's security features are engaged. If the light is flashing while the car is parked, it is normal; however, if it remains on when the vehicle is running, it may indicate a problem with the system.
To remove condensation from Volkswagen TDI Jetta tail lights, first, check for any cracks or damaged seals that may be allowing moisture to enter. If found, replace the damaged parts. You can also remove the tail light assembly, dry it out with a cloth, and use silica gel packets or a hairdryer on a low setting to evaporate any remaining moisture. Finally, reassemble the tail light and ensure it is sealed properly to prevent future condensation.
On a 2005 VW Jetta TDI the timing belt should be inspected at 80,000 miles and replaced at 100,000 miles. Neglecting to do the belt could result in your car breaking down on you when the belt jumps, and further damage to the engine resulting in costly repairs. Since a 1.9 TDI engine is a high-compression diesel engine, it is an interference motor. This means that a snapped or jumped timing belt may result in having to rebuild/replace the engine which could run upwards of $4000. In most cases a jumped timing belt would damage only the heads but it is possible it may do more damage depending on the circumstances when it broke.
The letters of TDI stand for Turbocharged Direct Injection. While many people may think that the 'D' stands for diesel, this is not the case. It is true that TDI's take diesel fuel, though. Try to ensure that you only take diesel fuel with cetane levels above 48 or 49. BP currently offers the highest grade, so use theirs whenever possible. Avoid truck stops, because their fuel will have the lowest grade fuel (as low as 40).
The system will purge its self of air, however if you are having trouble getting the car to run you may not have filed the filter. Fill the filter with diesel, then just keep turning the thing over until it fires off.
