Check the Engine Oil Level (No Dipstick)

Your Land Rover Discovery (2017–present) has no dipstick — you check the engine oil level electronically, through the driver display. It catches a lot of owners out, because there’s nowhere obvious under the bonnet to pull a stick and wipe it. Instead the engine carries a level sensor in the sump, and the reading is shown on a scale in the instrument cluster. Once you know where to look it takes barely a minute, and it’s worth doing regularly between services so a slow oil consumption never turns into a low-oil warning at the worst moment. Here’s how to get an accurate reading and how to top up without overfilling.

Why There’s No Dipstick

A traditional dipstick gives a snapshot of the oil level in the sump when the engine is cold and settled. The Discovery replaces that with an oil-level sensor and reports the result digitally, which is why the check is done from the driver menu rather than under the bonnet. The trade-off is that the reading is only valid under the right conditions: the oil has to have drained back into the sump and the vehicle has to be level, otherwise the electronics either refuse to show a figure or give one that swings. Treat the on-screen level exactly as you would a dipstick reading — a guide to whether the engine needs a top-up, not an invitation to fill to the brim.

Before You Check

For an accurate electronic reading the car needs to be prepared correctly:

• Parked on level ground — a slope throws the sensor off;
• at operating temperature (drive it, then let it stand a few minutes so the oil drains back into the sump);
• with the engine off when you take the reading;
• the correct oil to hand before you start, in case it reads low;
• a clean funnel or the bottle’s own spout so you can add small amounts without spilling.

Checking the Oil Level

1. Switch the ignition on (engine off).
2. Scroll the driver information display to the vehicle/service menu.
3. Select the engine oil level readout.
4. The display shows the level on a scale. Top up only if it reads low, a little at a time, re-checking as you go — don’t overfill.

Use the oil specification on the filler cap / in the handbook — it differs between the petrol and diesel engines, so don’t assume a grade from another model. Add in small amounts, let it settle, and re-read before adding more; overfilling a modern engine can damage seals and upset the emissions system.

If the Reading Looks Wrong

• ‘Not available’ or no figure usually means the engine is too hot, the oil hasn’t settled, or the car isn’t level — let it stand a few more minutes and retry on flat ground.
• Reading swings each time — the oil is still draining back; wait longer before trusting it.
• Don’t overfill — add small amounts and recheck; you can always add more, but draining excess is a workshop job.
• Oil warning light on? Stop and investigate — a low oil-pressure warning is a different, more urgent thing than a low-level message, and a stored code can be read on autodtcs.com.

After You Top Up

Once the level reads correctly, refit the filler cap firmly, close the bonnet, and start the engine briefly to circulate the fresh oil. Let it stand again and take a final reading to confirm you’re in the normal band. Keep an eye on how quickly the level falls over the following weeks — a small, steady drop is normal on some engines, but a fast loss is worth investigating before the next service.

Frequently Asked Questions

How do I check the oil on a Land Rover Discovery without a dipstick?

Switch the ignition on with the engine off, then use the driver information display menu to select the engine oil level readout. The Discovery uses an electronic sensor in the sump instead of a dipstick, so the level is shown on a scale in the cluster rather than read under the bonnet.

Should the engine be hot or cold when I check?

Warm it up by driving, then let it stand a few minutes on level ground so the oil drains back into the sump before you read the display. Checking straight after switching off, or on a slope, gives an inaccurate figure or no reading at all.

How much oil do I add?

A little at a time, re-checking the display after each small amount. The gap between low and full on these engines is not large, so it’s easy to overshoot — never fill in one go and never overfill, as excess oil can damage seals and the emissions hardware.

What oil does the Discovery use?

The grade is engine-specific and differs between the petrol and diesel units, so use exactly what’s listed on the filler cap or in the handbook. Don’t borrow a specification from another vehicle; the wrong grade can affect the particulate filter and long-term engine health.

Why does the display say the oil level isn’t available?

That message almost always means the conditions aren’t right yet — the engine is too hot, the oil hasn’t settled, or the car isn’t level. Move to flat ground, wait a few minutes with the engine off, and try again; it’s rarely a fault with the sensor itself.

Can I still get an oil warning even with no dipstick?

Yes. The car will warn you if the level drops too low or if oil pressure falls, and these are different warnings. A low-level prompt asks you to top up; a pressure warning means stop and investigate. If a fault is logged alongside it, the code can be decoded on autodtcs.com.
