I have been to three garages who have diagonistic tested the car. All show no faults. However the car sruggles to idle and cuts out below 1000 revs. This causes problems at junctions and traffic lights. The car drives okay and responds to acceleration. The car is x plate 2000 1.6 petrol with 81200 miles on the clock I am totally at loss as to the problem. Everything seems to check out okay Can you offer any advise Thankyou.

It could be anything, maybe a sensor, fuel problem, electrical fault, throttle body, etc You should have a garage run a diagnostic to get more info then...
Better to ask your question with more detail on a Renault forum, you will have to give as much info as possible. Renault Forums Independent Renault forum Powered by vBulletin
Thats the problem,a diagnostic computer just gives data,it doesnt mean that the problem a lean bank can be a vacuum leak a MAF code can be a slipped timing belt,Its all in data,whats the data,the protocal,lets face it,renault has a lot of problem to begin with,you just need the symptoms what does this car do is it a load problem or a idle problem,If one injector has a short it short out the one before,and the one after it,but it doesnt show up on a diagnostic scanner you need a labscope and a person behind it who knows how to use it.so what does this vehicle do?
this is a common fault for Renault scenics.its the central locking/immobiliser system,and would you believe it, as the fault is intermitant(sometimes it shows,sometimes not)you will need to let the garage drive it around for a WEEK OR TWO so that they can put the diagnostic computer on everytime they turn it off.the last one i did took a MONTH.(swopped cars with the customer she drove mine,i drove hers).she now never locks it.with the remote.
Are u sure that the bulbs are OK? I had no dipped lights on mine, & thought it must be a fuse or another electrical fault. It turned out, both bulbs had gone. I think this often happens when one side goes, the other soon follows.
IT COULD BE A NUMBER OF THINGS THAT ARE FAULTY, FROM LOW FLUID LEVEL IN THE COOLING SYSTEM TO A SERIOUS ENGINE FAULT. I SUGEST TAKING THE VEHICLE TO A LOCAL GARAGE, IT DOES NOT HAVE TO BE A MAIN DEALER, MANY INDEENDANT GARAGES HAVE DIAGNOSTIC EQUIPMENT TO TEST YOUR VEHICLE AND THEY WILL TELL YOU WHAT THE FAULT IS AND THEN YOU COULD ALWAYS FX IT YOURSELF.
