Car Won’t Start

This can sometimes be the million dollar question. There are so many reasons why a car won’t start. We will try to cover some of the signs to look out for. What you can do and what you can’t.

Some of the most common causes of why a car won’t start

  • Something electrical was left on in the car, like the lights, which ran the battery down.
  • You haven’t driven your car for a long time.
  • A fault with one of the battery components.

  • If you’ve run out of AdBlue, you won’t be able to restart the engine. You may have to call out a mechanic as some car models need software to restart them.

What is AdBlue?

AdBlue is an exhaust fluid, not a fuel additive. It’s stored in a separate reservoir and is topped up via a (usually) blue filler cap located either next to your fuel filler, in the boot or under the bonnet.
