How to tell when your diesel’s due for a service

Spotting small problems early and getting them serviced means your diesel engine runs smoother, lasts longer, and keeps your fuel costs down. Here are some common signs it’s time for a service.

Give us a call

Recommended Maintenance Schedule

Your car’s manual will have a recommended service interval. Typically, every 10,000–15,000 kms or as a rule of thumb, every 6 months. Less for performance cars.

Dashboard Warning Lights

Look out for a wrench icon, “Service Due” message, or a check engine light. These are your car’s way of waving a red flag.

Unusual Behaviour

If your car isn’t performing like it used to, it could be time for a service. Things like sluggish acceleration, rough idling, more smoke from the exhaust, reduced fuel efficiency or unusual noises are some of the tell tale signs.

DPF Troubles

Emissions systems like DPF, EGR and Ad Blue require routine servicing and maintenance to operate efficiently. Check out our Emissions Solutions page for more information.

FAQs

Got questions about diesel car servicing? Our FAQs are here with the answers. Learn how regular servicing keeps your diesel performing effortlessly and staying road-ready.

How often should a diesel car be serviced?

You should aim to have your diesel serviced every 12,000 to 15,000 kilometres, or every 6 months, whichever comes first. Regular servicing keeps your engine running strong, prevents issues from sneaking up on you, and helps keep those fuel savings flowing.

What does a diesel car service include?

A diesel service at Willy’s covers everything your engine needs to stay in top shape. From oil changes and filter replacements to checking fuel injectors, cleaning the fuel system, and ensuring your engine is running smoothly. We’ll run diagnostics to catch any hidden issues, so we can address them before they become a costly problem. In short, we make sure your diesel is firing on all cylinders.

Does it cost more to service a diesel car?

Diesel cars can be a little more involved when it comes to servicing, but that doesn’t mean you have to break the bank. At Willy’s, we keep our pricing fair and transparent. While some services, like fuel system cleaning or injector work, may cost a little more than a regular petrol car, the benefits of a well-maintained diesel are worth the investment.

Can skipping a diesel service really cause damage?

Absolutely. Skipping a service can lead to clogged filters, dirty oil, and worn-out parts, all of which put extra strain on your engine. Over time, this can cause serious damage, reduce fuel efficiency, and even void your warranty.
