Volkswagen is constantly developing new technologies for their foreign cars and our mechanics at Executive Automotive continue to stay updated in order to provide quality service and repairs. If you own a Volkswagen, congratulations. Even if you can’t afford a supercar, you still choose to go after great value. Volkswagens are great but they’re not free of problems, like any other vehicle. The most frequently occurring problems with Volkswagen are discussed below:
Coolant Temperature Sensor and Greater Fuel Consumption
Check engine lights annoy many vehicle owners, especially when they can’t find the root cause. Many things may lead to this light flickering on, but for Volkswagen users, it might be greater fuel consumption caused by a fault in the coolant temperature sensor.
Despite attempts to solve this through updates by VW, the problem still happens and the engine management system is fooled into thinking that the engine temperature is falling. To deal with this faulty drop in temperature, a heavier air-fuel mixture is used by the engine management system.
The check engine light also turns on as a result. Only professional technicians can do away with issues if they have worked on similar Volkswagens before.
A Gap in Communication
The OBD or onboard diagnostics is available for many models of Volkswagen vehicles, which sometimes fails to diagnosis results because the power source has been tampered with.
Aftermarket radios can lead to the OBD connection problems. The wire leading to the OBD port’s power source is the go to attachment wire for any aftermarket radio. This interference causes problems with the cars OBD system.
The aftermarket radio technicians don’t pay much attention to where they are connecting wires and what wires they are splicing, which is a problem. This problem can only be solved when the aftermarket radio is uninstalled and connected to a different power source.
Volkswagen owners have complained about rattling coming from the center of their cars. This happens when the muffler bracket fails to hold its position. Welding the broken section will solve this problem as there is no need to replace it. But if left un-repaired, it can damage the rest of the exhaust system.
Rear Rattling on Bumps
A rattling at the rear of a Volkswagen can be the result of a number of problems. The most common problem of these is failing rear suspension. If the shock absorbers break at the bottom, they will leave the rest of the springs dangling and clanking, causing further damage to the housing where the spring is placed. When the car goes over bumps, the broken pieces of spring start rattling.
Cam seal leaks at either position on the cylinder head are the most annoying causes of leaking oil. The seal needs to be replaced and installed very cautiously.
