TOP 4 VOLKSWAGEN REPAIR PROBLEMS
Power windows, power locks, interior lights, car alarm, auto radio, or any other electrical components that refuse to work on many occasions? The problem here may be the electrical wiring. This one takes just a simple solution to fix, though: check the connections, especially at the grounding post points. First, see if there are loose or poor connections and tighten them properly. Second, check if there are connections already on the verge of corrosion and clean or replace them as necessary.
Signs of problems in charging and starting suggest that a battery check is in order. Actually, it is only a matter of visual and voltage testing with the help of a couple of handy devices: a digital volt ohmmeter and a battery charger. For example, if the battery is already in need of charging, the color of the "eye" found on the battery would indicate so. However, this color varies among battery brands, so it is advisable to be familiar with the charge indicator color and what each says about the battery charge condition, i.e. Good, Needs Charging, Low fluid level; battery should be replaced. Now, in case it seems as if the battery already needs to be replaced, it would be wise to have both the current battery and the electrical system tested first to discount what could be a problematic starter or alternator. For the correct replacement battery, it must have the same or higher cold cranking amps as the original. Also, it must be of the size that would perfectly fit the battery tray and cable connections.
Often characterized by a slow cranking engine, a malfunctioning starter is likely to pose bigger concerns since it consumes most of the power the battery generates. So it is best to replace it as soon as possible. In fact, not only should the starter drive or Bendix be replaced but the entire starter assembly. All of these other starter parts might just be as worn and torn as the starter due to long and heavy usage as well as heat stress after all. Upon replacement of the starter assembly, it should be checked together with the electrical system to ensure everything works properly. For starter maintenance, one good tip is to make it a habit to turn off the audio component, air con compressor, blower motor, and any other parts that eat up too much electricity before starting the car. Starter overuse and overheat should also be prevented.
Once the timing belt breaks, the engine dies, too. So it is advisable to watch out for any unpleasant noise or smoke coming from under the hood as the timing belt is subjected to the stress brought about by its function and the extreme temperatures where it is located. In either scenario, preventive maintenance is a must. This means replacing both the timing belt and the water pump on a regular basis, depending on the owner manual's recommended mileage for replacement.
