Spanner light (DIM AND FLICKERING) and fuel injection/gearbox light

Hi all, I current share the use of a Renault Twingo Extreme 2009/10 1.2 Petrol.



Back story:

So tonight I was driving back from the mc donalds drive thru to see these two symbols on the dash slightly dim (like a torch running out of battery that kinda brightness)



I didnt think nothing of it till i got home.. i switched the ignition off and pulled the key out, turned the lights off etc etc and these two lights were still on.. (the spanner/wrench what ever you call it and this fuel injector/gear box light a bit like a heart rate monitor)



I restarted the car gave it 2000 rpm (hoping that would do something) and with no success these dim lights were there.. So repeated process everything off keys out, this time the lights went off.. so I went in and got the user manual out and its saying that the car shouldnt be driven and taken to a dealer yet the lights have gone out when i went back and checked about 20 mins ago and the car ran fine down the street when i ran it too 3500 rpm in first then changed gears.



Should i be worried about this or is it just Renaults terrible electrics as per playing up?
