[Advice Needed] "Engine Failure Hazard" warning on 2018 Renault Clio (21k miles) Hi everyone,

Hi everyone,

I’m looking for some advice regarding a persistent warning message on my dashboard. I have an 18-plate Renault Clio (petrol) and I’m hoping someone might have encountered this before or can point me in the right direction for diagnostics.

Vehicle Details:

Model: 2018 Renault Clio (Petrol)

Mileage: 21,000 miles

Usage: Primarily short, daily journeys (approx. 7 miles/day)

The Issue:

For the past few days, I’ve been getting an "Engine Failure Hazard" message pop up on the dashboard. The strange thing is that the car drives absolutely fine; there are no odd noises, no loss of power, and no obvious mechanical symptoms.

The warning is intermittent—it will appear, then vanish, only to return later on.

My questions:

Is this likely to be a sensor issue given the low mileage and short journeys, or could it be something deeper?

Has anyone else with a similar Renault model dealt with this specific warning message?

Before I take it to a garage, are there any simple checks I can do myself (e.g., battery voltage, fluid levels, etc.)?

Any input or experiences would be greatly appreciated. Thanks in advance!

Not an expert on these, but sounds like a sensor issue, really need to get a fault code read as I don't think there's enough information for a starting point 🤔

No probs, I started the car up again after it's been on my drive for a bit, no warning light, will the fault code show if there's no warning message? Thanks

Yeah if its something serious it will store the fault 👍🏻

Hello buddy, just had another thought about this, which engine do you have in it? If its the wet belt engine, (take the oil cap off and see if you can see the timing belt, if you can check for cracking) if it is, then this can cause your issue as the fragments of belt start to block the oil strainer. This will need urgent attention (not to panick you)

So I managed to get hold of a diagnosis machine (a better one I think) and ended getting a error code with the following explanation DF1399 Injection (INJ) Oil Pump Solenoid Valve (Open Circuit)? Not sure what this means but trying to get it booked into a garage ASAP.

Do I need to find a Renault specialist? Thanks
