Common Vauxhall Insignia Electrical Issues

I'm having trouble with my Vauxhall Insignia's electrical system. The car won't start and the headlights keep flickering. What could be the problem and how can I fix it?

It sounds like you may have a faulty battery. Have it checked and replaced if necessary.

Check the fuses for any signs of damage and replace them if needed. This could be the cause of the flickering headlights.

If it's not a battery or fuse issue, it could be a problem with the alternator. Have a professional diagnose and repair this for you.

Make sure all the connections in your car's electrical system are secure. Loose connections can cause these types of issues.

Consider getting a diagnostic test done on your car to pinpoint the exact issue. This will help save time and money on unnecessary repairs.
