A structured maintenance schedule and replacement intervals together form the basis for keeping your car reliable for years. Engine oil, filters, brake fluid, timing belt kit and water pump should be replaced at fixed intervals. This applies even if you are not yet noticing any problems. For a commercial vehicle such as the Peugeot Expert, the usage profile also plays a major role. Lots of short journeys accelerate wear. Heavy loading does too. Which intervals are really important? And what happens if you ignore them? Read on quickly.
What is the right maintenance schedule for my car?
Your car’s maintenance schedule determines what needs to be checked or replaced and when. Always follow the manufacturer’s instructions for the model year, engine type and usage profile of your car. Intervals can vary by version. Modern cars often use maintenance based on time or mileage. Whichever comes first is decisive. In addition, the dashboard increasingly warns you automatically when a service is approaching.
For most passenger cars, regular maintenance is due roughly every 12 months or 15,000 to 30,000 kilometres. For commercial vehicles, these intervals can be longer. However, that does not automatically mean you can wait longer. Do you drive a lot in town with short trips? Do you also often carry heavy loads? Then earlier maintenance is often sensible. If you are specifically looking for the correct intervals for your van, the maintenance page about the Peugeot Expert is a good starting point.
Checking the maintenance schedule without the booklet
No maintenance booklet left in the car? No problem, you can usually find the schedule in other ways:
- Ask the dealer or a specialist garage for the schedule.
- Check the digital service message in the dashboard. Many modern cars indicate an upcoming service themselves.
- Keep your own maintenance log with date, mileage and work carried out.
How often should I change the engine oil?
Engine oil and the oil filter form the basis of any maintenance schedule. As a practical guide, this is often once a year or around 15,000 kilometres. The exact interval depends on the engine and use. Do you regularly drive short distances? Then the oil reaches its working temperature fully less often. Contamination therefore occurs more quickly. Check the oil level regularly, too, even between scheduled services.
Other fluids with a fixed replacement cycle
Other important fluids are:
- Brake fluid: usually every 2 years. Brake fluid absorbs moisture. This lowers the boiling point. Under heavy use, braking performance can therefore deteriorate.
- Coolant: often every 4 to 5 years or according to the manufacturer’s interval. Old coolant protects less effectively against corrosion and frost.
These parts wear with mileage. They also wear with age. Does your car do few miles? Even then, it may still be time to replace these fluids.
When should the timing belt kit be replaced?
The timing belt kit and water pump are among the most critical replacement intervals in the maintenance schedule. This means that exceeding these intervals can lead to serious, costly damage. Replace these parts at the point specified by the manufacturer and engine type. Exceeding the interval can lead to severe engine damage. In general maintenance guidelines, this interval often varies between 60,000 and 120,000 kilometres. In years, this is often 5 to 8 years. Many garages replace the water pump at the same time as the timing belt kit. Both parts are located in the same place in the engine.
Tyres also deserve attention within the broader maintenance schedule. Incorrect tyre pressure increases both wear and fuel consumption. Check tyre pressure regularly when the tyres are cold. Too low a pressure increases wear. Fuel consumption also rises.
What are the consequences of neglected maintenance?
Putting off maintenance may seem to save money in the short term. In the long term, however, delay often leads to higher costs and greater risk. A timing belt, for example, can wear out. If it snaps, this can lead to costly engine damage. Old brake fluid, meanwhile, reduces braking performance at the very moments you need it most. Think, for example, of heavy use or long descents.
So look out for signs that may point to overdue maintenance:
- Warning lights on the dashboard that stay on or come back on.
- Vibrations, strange noises or smells while driving.
- Visible fluid leakage under the car.
- Noticeable loss of power or rough idling.
As soon as one of these signs appears, it is wise to have it checked sooner. The scheduled interval does not necessarily need to have been reached. Especially for commercial vehicles used intensively, preventive maintenance avoids more expensive repairs. Failure of the brakes, tyres or engine components is thereby prevented.

Combining maintenance with fixed times of year
Whenever possible, schedule maintenance well before the MOT. Any defects can then be repaired in time. Many owners combine maintenance with seasonal changes. Think, for example, of switching from summer to winter tyres. That keeps the schedule clear. Replacement dates are less likely to be missed. Keeping your own maintenance log helps with this. It also increases the car’s residual value if you decide to sell it.

Frequently asked questions
A precise maintenance schedule ensures that wear-prone parts such as oil, filters, brakes and belts are checked and replaced on time, greatly reducing the likelihood of faults. This keeps the engine cleaner and better lubricated, which extends your car’s lifespan. Well-planned preventive maintenance avoids costly repairs caused by damage when parts are used “to the limit”. It also keeps the car safer and more reliable, because brakes, tyres and fluids remain consistently in good condition.
With intensive use or track driving, it is especially the **brakes** (brake pads, discs and brake fluid) and **tyres** that need extra attention and a higher replacement frequency. **Engine oil and the oil filter** also need changing more often because of the greater thermal load. In addition, parts of the **suspension and steering** (rubber bushes, control arms, dampers) may wear more quickly and require additional inspection.
You can safely check the tyre pressure and oil level yourself and top them up if necessary according to the owner’s handbook. Topping up washer fluid and coolant (but never opening the system when hot) is generally permitted without voiding the warranty. You can also sometimes replace filters such as the cabin filter yourself, provided you use original or approved parts. Always stick to the manufacturer’s service intervals and have brakes, the timing belt and electronic systems handled by an authorised garage.
No, the manufacturer’s standard replacement intervals are not always optimal for every situation. They are based on “average” use; with lots of short trips, heavy loads, lots of city driving or dusty/salty environments, earlier maintenance may be sensible or even necessary. Ageing over time (even with low mileage) can also be a reason to replace parts or fluids sooner than the mileage schedule indicates. It is therefore wise to use the manufacturer’s instructions as a basis, but to refine them according to driving style and environmental factors.
Warning signs include unusual noises (squeaking, grinding, ticking), vibrations or an abnormal driving feel. An increase in braking distance, pulling to one side when braking, loss of power, smoke, noticeable smells or visible fluid leakage are also signs. In addition, warning lights on the dashboard, repeated topping up of oil or coolant and uneven or rapidly wearing tyres point to accelerated wear. As soon as such symptoms occur, a part may need replacing earlier than the formal maintenance interval suggests.
