Jargon Buster

We understand that not everyone who owns a vehicle is not a fully trained mechanic. In order to make things a little clearer we have made a Jargon Buster just for our customers.

Most of the time we talk directly to your repairer to figure out what issues are occurring with your vehicle. 

However, if you are dealing with your repairer and the wording they use is confusing and you would like to understand more of what they are saying, please contact us as we shall try and assist you to the best of our ability on claim@autoguardwarranties.com. 

 

Anti-lock Braking Systems (ABS) 

Prevent your wheels from locking up so you can maintain grip on the road when you press hard on the brake pedal.

 

AGM or Absorbent Glass Mat Batteries

Are well known for their performance in stop/start engines. They’re more reliable than conventional lead-acid batteries when starting an engine from cold and are well suited to vehicles with sophisticated electric systems.

 

Dampers or Shocks 

Minimise the up and down motion in a car when tyres hit bumps in the road. They are usually used alongside springs to form the suspension system for a smoother ride.

 

DPF

Can be found in the exhaust system on diesel cars.

 

The Diesel Particulate Filters (DPFs)

Are fitted on cars to collect soot and reduce emissions.

 

Drivetrain

Refers to the group of components that allow the car to release its full power. This includes the engine, transmission, drive shafts and drive wheels.

 

Engine Management Light (EML) 

Will illuminate on your dashboard if there’s a problem with your engine module. The light is connected to the engine control unit and sometimes referred to as the ECU light.

 

Excess Play

Mechanics may use the term excess play to describe a steering wheel that turns without properly moving tyres. Think of it as extra ‘give’ in your steering.

 

Hybrid Cars

Are designed to use more than one means of propulsion. They’re powered by either petrol or diesel engine and an electric motor. They use less fuel and have reduced CO2 emissions when compared to conventional cars.

 

Malfunction Indicator Lamp (MIL)

Is another name for the EML light. It will light up when there’s a problem with the fuel management system or the ‘electric brain’ of your engine.

 

Tyre Pressure Monitoring System (TPMS)

Does exactly what it says on the tin. The tools measure tyre pressure and give a reading in bar (metric) or pounds per square inch or PSI (imperial).
