A Simple Remedy for the Low Coolant Level Problem on the Volkswagen Passat

Model: Volkswagen Passat B6, 3C - Years 2005-2010
Part: Antifreeze coolant

In this video, see how to solve the issue of a low coolant level on a Volkswagen Passat very simply. However, our YouTuber also had to visit the mechanic and had to think hard before understanding what the problem could be. Initially, he had to top up the coolant level approximately every two weeks. The workshop found no visible leaks, and the pressure test was negative; the water pump was not leaking. Then came the lightbulb moment: the coolant reservoir cap was not holding pressure. We found it on Amazon with the code B072BY7TK1 for £11.50, with free delivery for Prime customers, and the problem was resolved.

How to Reset the Central Locking of the Volkswagen Golf 4?

If the central locking system of the Volkswagen Golf 4 is not working, it is likely necessary to reset the system: to do this, open the driver's door and detach the side panel of the dashboard next to the steering wheel. Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14.
