At the press of a button all the faults was gone and the car is running like new again.
He explained it to me like an ordinary pc that gets clitches and needs to be rebooted, the ecu can do the same from time to time and needs a reboot.
If you take it to be looked at, always ask if they have the up to date software loaded as renault are constantly updating.
Good luck.
Does the ecu on a Renault not reset itself when you disconnect the battery for at least ten minutes and reconnect it? It does on my Transit and most of the other cars I've worked on, but you need to let idle for a while on restart and then a drive a few miles nice and steady. On newer models Mercedes in particular you can not do this.
Currently in worstcasescenario's garage:
Ford Transit, 2.0 dohc 114 hp Renault Scenic 1.6e Peugeot 205 1.1
