Dacia Duster fuel gauge

Recommended Posts

My 19 plate Duster when under the manufacturer warranty had a problem of the fuel gauge not registering correctly. The software related to this was worked with and seemed OK.

Took my car for its first mot recently, and now a week or two later the gauge is playing up again. Put petrol in and the gauge doesn't move up but it did go down one bar after some mileage.

I know on older cars they worked off a float type set up. So how do the digital with bars we have now work ?

Anybody with a Dacia Duster have the same problem ?

I had a 2014 Duster for a while. From being on the Duster Owners Facebook group, I seem to remember the fuel gauge thing being a known issue.

Something to do with the tank being ‘brimmed’ with fuel.

If you’re on FB, head over to that group 👍

Mmmmmm. Food for thought. I just fuelled my 2021 to the brim at Costco (petrol £1.51 litre). Fingers crossed.

Yeh next time you need fuel, just fill to maybe 3/4 and see if the gauge works properly then. I think the issue was that the sensor device can’t recognise the volume of fuel if the neck of the tank is full… something along those lines.

Well there might be an answer.

When I put petrol in I did not plan to fill it full, but there might be some truth in ' brimming' it and gauge problems. I had 4 bars, put about £25 quid in and it stayed on 4 bars then dropped to 3 after a little running around, then stayed on 3. After a little bit more running around it went up to 7 bars, dropping to 6. Max. on gauge is 8 bars.

I had booked it in to a Dacia dealer, who agreed to look at it for free. I told them it seemed to be OK now, and was it worth still investigating. They said yes.

They came back to me with a faulty sensor. They said they would contact Dacia to see if they would authorise repair. But part is a 5 to10 day delivery, as they don't carry all parts stock on the shelve.

Bit of running back and fore, but let's hope it comes good.

Well that's what they told me. The same thing happened just under a year ago, then they told me that they done something with the software.

I have never on any car I have owned intentionally filled the tank to full capacity.

Oh well, they’re sorting it out, so that’s a result 🙂
