Espace low coolant check engine

A consistently low coolant level with a check engine light suggests a leak somewhere within the cooling system. First, check for any visible leaks around the radiator, hoses, water pump and the engine itself. Also, inspect the radiator cap – a faulty cap can prevent the system from pressurizing correctly, leading to coolant loss. Have you checked the oil for any signs of coolant contamination? That would indicate a head gasket issue.

Thank you for your response. I examined the engine oil and found no coolant contamination. Where exactly are the common leak points?

Given that you've ruled out head gasket issues, focus on areas that are prone to leaks due to wear or damage. I would check all hose connections first, as these can sometimes loosen over time. If you can't find the issue, I recommend a pressure test of the cooling system at a workshop—they can introduce pressure and more easily find the leak point. It is possible that it is just a defective cable or plug connection of a component.

I appreciate the advice. I took it to a workshop, and they found a defective cable/plug connection. The repair cost me 95€. Thanks for your help.
