The other halfs Megane has developed a wee problem, it starts fine but after a time of between 10 seconds and up to 5 minutes it switches off after lighting up a couple of lights on the dash.
I have checked the drivers handbook and the combination of lights show either a serious injection incident or a coolant temperature warning. The car as said starts and runs ok but cuts out after a wee while.
Could it be a temp sender or something similar?
Cheers in advance
Craig

The handbrake light which also serves as a warning light along with the one that looks like an engine with stop written inside it

this could lead to various reasons. it would be easy if you had a fault reader.its cheap to buy one and usefull . i will check it but for now check the crank sensor , is on top of the g/box close to the engine. clean it and spray some oil on the connector. the crank sensor when faulty , suddenly cuts off the engine.

It just cuts off, no messing just stops the engine, but will start immediately again after turning the ignition off. I am by no means a mechanic but am fairly handy if you could point me in the right direction

just another avenue to explore the ide engine does suffer from problems relating to the fuel pressure regulator and is quite common and can cause the problems you have explained . you really need to get the faults stored read by a fault reader to determine what is actually going on, as above tdc sensors on renaults can cause problems also.

Its now been on the fault reader and no faults are showing up at all even though the car is switching off when the computer is plugged in?
How can I check if its the fuel pressure regulator

pain you have no faults.
firstly check your fuel pump is working correctly and the relay is ok.. if you can with the fault reader check the engine parameters before it cuts out to see what the fuel pressure is doing.
dont discount the fact that the tdc sensor is faulty because they do cause problems and you normally have to change the plug connector with it as the plug connector can be the problem. and the symptoms can be similar to your problem have you had poor hot starting recently as this can also happen when the tdc sensor starts going down bit of a pain to diag over the pc tbh good luck

Fuel pump is working fine I can hear it running, TDC is the likely suspect then by the sounds of it

if you clean the tdc and continues doing it then better replace it.did you find where it is?

I think so, its the one held in to the casing using a couple of bolts on what looks like a mount of some kind. I will get it removed and cleaned later, its a pretty tight spot is it not

I managed to get the TDC sensor removed and cleaned although it wasn't too bad, refitted and still the same. The warning light actually comes on without starting the car if the ignition is left on for twenty seconds or so.
It still starts fine but lasts for a few moments before cutting out. I think the dealer is the way to go now. Thanks for the help guys its much appreciated I will let you know what the outcome is for future

A wee update, the car is down at the Renault garage and after a bit of fault findining its turned out to be something to do with the EGR valve and possibly a bit of wiring.
Hopefully getting fixed as wee speak.
cheers for the help Guys

Praise has to go to Ness Motors, the Renault dealer they fixed the car and only charged £70. Thanks for the advice and help I know just a wee bit more about TDC sensors now than before LOL, cheers Craig
