Took my mums car to fill it up with fuel, 500 1.2 dual logic and the generic failure dash light is on. It's only done 4800 in 3 years and 2 months.

The book says it's oil pressure sensor or reverse sensors (which are not fitted)

Where is the oil pressure sensor ?

check the next page of the manual

Whatever it was it went away after three restarts, couldn't see any cause, no external lights out etc.

Guess will have to see if it comes back

Do you have stop/start?

Number plate lights and front lights working ok?

I will have another check today, I am going to drop it back to my parents today. It's not a stop start, but I did wonder if a low battery would cause it. Since July it's only done a few miles.

I put a solar panel on it for them, which seems to keep it topped up. Before the battery was almost flat most of the time due to no use.

It's morning it was back, but with a message saying check lights, turned out to be brake light bulb.

That's the first thing to be replaced since it was new !!
