Shoulda asked me for a lift mate! Unfortunately i have no real mechanical knowledge so cannot help. But if you're around sidcup then i have some tools etc.
hi mate i am a tech for renault, u will usualy find with these that the throttle body gets dirty and greasy needing a good clean out and reinitializing by your local renault dealer OR pedal potentiometers also play up, what did the fault say on diagnostic machine?
