This problem has only just occured on my scenic, it's great starting when cold ie early morning late evening. When you try and start it during the day it won't start, I have been told it's a faulty sensor but which one????? if anybody has any Idea's and can point me to where the sensor is located it would be much appriciated
Thanks

You need to start with getting the relevent fault codes without these its just a stab in the dark which could prove rather expensive.

I had itchecked by Renault last saturday and they said there's no problem???? so at the min all I want to do isto try and get it sorted. So need to find out where the sensors are so I can poss change them.

The cost of the sensors [and other parts] that you'd have to sequentially change, to stand a reasonable shot of fixing this, would exceed the value of the car.

Guesswork is a pretty expensive way of diagnosing the fault. However; if you're intent on trying: start with the crank [TDC] sensor - that's a 15% chance.
