If we detect any issues, we'll talk through what needs to be repaired. We’ll give you a no-obligation quote to fix it on the spot, if we can. Or we’ll recommend a local RAC Approved Garage, and give you a full error report to take there.

Frequently asked questions on glow plug repair

A glow plug heats the air in a diesel engine to help it start, especially in cold weather.

When a glow plug fails, your engine might be hard to start, producing more smoke, engine misfires, and poorer performance.

You can, but it’s not a good idea. It can lead to poor engine performance, increased emissions, and overall damage.

Glow plugs typically last between 60,000 to 100,000 miles. Read your car’s manual and have them checked regularly.

It’s tricky and needs specific tools, so it’s best to let a mechanic handle it.

Replacing faulty glow plugs can improve engine start-up, reduce emissions, save fuel, and prevent engine damage.

It depends on your car’s warranty terms. They’re often not covered since they’re a wear-and-tear item, check with your warranty provider.

Yes, all diesel engines use glow plugs for starting, especially in cold weather. Regular maintenance and replacements are vital for the best performance.

Failures can be due to electrical issues, carbon build-up, corrosion, or incorrect installation. Regular maintenance helps prevent this.
