Read our short guide with information on costs, symptoms and more.

What do glow plugs do?

Glow plugs were originally used to assist with starting diesel engines in cold temperatures when the heavy oil used to coagulate. Now that diesel has many additives to prevent this, glow plugs have taken on the role of heating the incoming fuel / air mix to provide greater efficiency while the engine warms up. This also assists with decreasing the noise during cold running.

How do glow plugs work and what are the components

Each cylinder will have its own glow plug, controlled by a glow plug relay (or by the vehicle's body computer module (BCM). When the ignition is initially switched on, a current is automatically sent to the relay to switch the glow plugs on. When the plugs are going through this cycle, normally the dashboard will show the pre-heat plug warning, which looks like a coil of wire. Once the glow plugs have heated up, the light will extinguish. Ideally, the engine should only be started once this light has gone out to provide their maximum effect.

Some newer cars, especially this with automatic stop/start systems have special glow plugs with pressure sensors in them. Normally, glow plugs are relatively inexpensive, ranging between £20-£30 each, however the pressure type can be at least five times this.

How do you know there is something wrong with the glow plugs?

You may experience some of the following symptoms

  • Glow plug warning light flashing when the ignition is switched on
  • Engine management warning light (EML) lit
  • Struggling to start from cold
  • Excessive fuel consumption while the engine warms up

When should you consider a glow plugs replacement?

If you are experiencing any of the above symptoms, ideally would have the glow plugs changed as soon as possible. If the engine is starting OK, though and there is no EML lit, then get the glow plugs changed when you are able to.

How common is a glow plug replacement?

The majority of diesel vehicles will go through their life without requiring them to be changed, however like all electrical units, they can fail, so it's a job that is carried out with reasonable frequency by the mechanics.

How can I extend the life of my glow plugs?

There is nothing you can do to reduce the risk of a glow plug failing.

What happens during a glow plug replacement?

  • The mechanic will pre-soak the glow plug threads with penetrating oil or similar and wait for it to take effect.
  • Mechanic will then ease the glow plugs undone and remove them one by one
  • New glow plugs will then be installed
  • Engine start up will be tested and error codes cleared down

NOTE

Glow plugs are notoriously difficult to remove in some circumstances.

As the plugs themselves are around the size of a pencil, glow plugs that have seized in position are susceptible to breaking. Should this occur, there could be a danger that the cylinder head would need to be removed in order to extract them.

Whilst the mechanics will endeavor to do their best to replace the plugs without this occurring, should it happen, the subsequent removal work will not be covered financially by the mechanic.
