Video tutorial

When carrying out maintenance tasks independently, it is possible to make mistakes, even unintentionally. Here are the 5 most common errors to avoid.

The first mistake is placing tools under the bonnet that you are using or will use, without moving them when starting the car. This can cause some tools to fall into the engine bay and damage components. It is advisable to keep tools on a trolley.

The second mistake is placing tools on the battery during maintenance, which could cause a short circuit. The third mistake is working in a dirty area.

The engine bay should be clean before starting maintenance to prevent dust from entering components. The fourth mistake is being careless about fluids that may spill onto the engine during top-ups. The fifth mistake is using incorrect torque settings when tightening components.
