Vehicle warning lights

Red dashboard warning lights

A red dashboard warning light usually indicates that your vehicle requires immediate attention, especially the lights relating to the engine, airbags or brakes. Book a diagnostic check with M6 Recovery Services for assistance.


Amber dashboard warning lights

An amber dashboard warning light usually indicates that your vehicle may need attention and leaving this unchecked could cause a bigger problem later, so it's best to get these checked as soon as possible.


Green or Blue dashboard warning lights

Green and blue warning lights tend to be general warnings. For instance, they could be telling you which lights are being used or whether your windscreen wipers and handbrake are on. However, you shouldn't ignore these lights, as they can also indicate that you have a fault so it is important to pay close attention to any warning light that appears on your dashboard.


If you notice a red or an amber warning light then it is very important that you don't just leave it, get your vehicle booked in for a car diagnostic test.

What does a Diagnostic Check include?

The diagnostic check will include a full vehicle system health check. The scanner will identify all modules connected to your vehicle’s  ECU and individually check for any stored or current faults.

The scanner will identify if the fault is ‘Current’ or ‘Stored/Historic’ – any stored or historic faults will be cleared from your vehicle’s ECU memory. Any current faults will indicate that something is not as it should be, and in most circumstances, we should be able to advise what work may be required.


The diagnostic check does NOT include the cost of repairs, replacement parts, recoding, etc. Where we are unable to offer a suitable repair (i.e. electrical system faults) we provide you with the fault codes that should enable you to obtain repair quotations from a specialist.

Engine management lights may not extinguish if a fault identified is not rectified.
