Check the Engine Oil Level

There’s no dipstick under the bonnet of your Volvo V40 (525, 2012–2019) — you check the engine oil electronically through the instrument-cluster menu. If you’ve lifted the bonnet hunting for a dipstick and found none, don’t worry: that’s how this generation is built, not a missing part. The reading comes from a sensor in the sump and is shown on the cluster, but it’s only reliable if you take it under the right conditions. This guide covers how to get a trustworthy figure and how to top up without overfilling.

Why There’s No Dipstick

The V40 uses an electronic oil-level sensor in the sump rather than a manual dipstick. It measures the oil that has drained back into the pan and reports a level to the cluster software. That works well, but the car can’t register oil you’ve just poured in or drained out until it has settled and the engine has run. Read the level cold, on a slope, or immediately after adding oil, and you’ll get a misleading figure. Everything about getting a good reading comes down to sequence and patience: warm oil, level car, a short settle, then read.

Getting Ready

• Park on level ground so the oil sits evenly across the sump and the sensor reads true.
• Take the reading with the engine warm — check after a drive, not from cold.
• Have the correct approved oil ready if you plan to top up; the grade is on the filler cap and in the handbook.
• Keep a funnel and cloth handy to add oil cleanly and avoid spills on a hot engine.
• Know your ignition positions — you need the key at position 2 (on, engine not running) for the menu.

Getting an Accurate Reading

1. Drive the car so the oil is warm, then park on a level surface and switch off for a few minutes so the oil drains back.
2. Turn the ignition key to position ‘2’ (on, engine off).
3. Use the stalk controls to scroll the cluster menu and select ‘Oil level’.
4. Read the level on the display and top up if necessary, then switch the ignition off.

Topping Up

Add the correct approved oil a little at a time, re-checking between additions — don’t exceed the maximum. Small pours are safer than one big glug, because overfilling is as harmful as running low. After an oil change the system needs the engine run and settled before it shows the new level accurately, so give it a drive cycle before you trust a post-top-up number.

If the Reading Won’t Settle

• Confirm the car is truly level — even a gentle driveway slope moves the reading.
• Let the oil drain back longer if you checked very soon after switching off.
• Make sure the engine was properly warm; a brief cold run gives a thick, unrepresentative reading.
• If an oil-level or service message appears and won’t clear, treat that as separate from a routine check — it can point to a sensor or oil-condition issue.

What Happens Next

With warm oil, a level car and a short settle, the cluster figure should be steady and repeatable. If you’ve just topped up, drive a short loop and check again to be sure you’re inside the safe band rather than acting on the first reading after adding oil.

Frequently Asked Questions

How do I check the oil on a Volvo V40 with no dipstick?

Warm the engine with a drive, park on level ground, switch off for a few minutes so the oil drains back, then turn the key to position 2 and scroll the cluster menu with the stalk to select ‘Oil level’. Read it and switch off when done.

Why does the reading seem wrong after topping up?

The sensor only measures oil that has drained into the sump, so freshly added oil won’t show until the engine has run warm and the oil has settled. Take a short drive after topping up, park level, and re-check — the level should then read correctly.

What oil does a V40 take?

An approved grade for your engine — the exact viscosity and specification are on the filler cap and in the handbook. Petrol and diesel units differ, so match the spec for your specific car rather than assuming a single grade fits all V40s.

Which ignition position do I need?

Position 2 — that’s ignition on with the engine not running. Turn the key to that point (without starting) so the cluster and menu come alive, then use the stalk to reach the oil-level display.

Does the V40 warn me if the oil is low?

It will show an oil-level message if the level drops too far, but don’t rely on that alone. Run the manual check now and then, especially before longer journeys, so you catch any consumption early and top up in good time.

Can I check it from cold in the morning?

A cold reading isn’t representative because the oil is thick and hasn’t circulated. For a figure you can act on, drive the car to warm the oil first, then park level, let it settle and read it at position 2.
