Hello again, thank you for your reply..

There is a common fault with these models - and this is whats known as the CKP - crank shaft sensor...

This is located on the top of the gearbox where it meets the engine - move the pipes etc to see it - and it is held on by 2 x 10 mm bolts.....

Unclip the connector and remove it - and fit the new one - supplied by a Renault dealer parts dept.. Dont be tempted to buy / use a non Renault one, they can be troublesome and don't last..Its a very straightforward job and again - a very common issue that causes the problems you describe. Its basically that the sensor gets hot - and shuts down.. this being the main trigger for the fueling system etc - it will cut your engine as if it has been switched off. When the sensor cools even momentarily, it will work again - until the next time..

If your old one is black - you will have to fit a "kit " that they will supply - comprising a new sensor and piece of wire loom - though on the 07 , it should be just a sensor really that you will be given.. Either way.. it still only takes 20 mins or so for whoever does it..so if you use a garage, its not an expensive job labour wise - the sensor is around the 50£ mark.

Just to mention too - this will 9 / 10 not show up as a fault on a computer - not when its an intermittent fault such as yours..

Of course you could have other issues - but that sensor is very very common on these - and fits with your description of the faults you have...so it would make sense to have that investigated / done. If you take it to Renault or another garage, they may want to run a diagnostic test to confirm , this is not unusual.

Im very pleased to have helped you -Let me know if I can help anymore...I will be back on system later in the day - and will always get back to you asap if needed.

thank you very much for the reply, one last related question, is this the only possible cause for the engine cutting off?

Picture
Expert:  Mike replied 389 days and 12 hours ago.

Hello again - thank you for your message - my apologies that I couldn't get back to you sooner ..

Its not the only possible cause - but it is the most common - and a known fault on these models...

I noted that you have had the injectors done - they are a cause of this issue too...but it shouldn't be that of course, not as you have had those done.

You can also get "rarer" faults causing cut offs - such as bad connections / wiring - even control unit / module or ignition faults that can cause a cut out - but that / those are rare - espeically on this year - whereas again, the crank sensor is a common issue and so should always be checked / addressed first as the cheapest / cost effective way forward...

I hope that helps you further -

Best Rgds- MIKE.
