Hi Roy

It could be many things causing this problem but we're going to start with the most common on Renault's testing the LED light on your instrument panel, when you install your key to start if it's flashing rapidly then the problem is with the immobilizer.

Suggestion number two the engine TDC sensor or in other terms the engine speed sensor also known as flywheel sensor which can be found under the airbox filter, mounted to the gearbox in between gearbox and engine, when the problem occurs place your hand and try to move the connector that is connected to the TDC and then try to start the engine normally it's a connector problem and not the actual sensor.
If this does not solve your problem I have further suggestions.

    I'm glad you found my solution helpful, for faultfinding/diagnostics on Renault's is my main daily job, after over 15 years of experience I'm happy to say it pays off.

Roy was right!! Pull out then plug in the TDC sensor male plug a few times and vroom!! The car starts.... Must be dirt or contacts do not conduct electricity after time. You have to put your car radio code in to get it working as well. It working on my Scenic RX4 2001 model. By the way I had to replace the gearbox on this car at 100,000km's...........

Renault megane scenic 1.9 dt r reg 1997 cold start problems

This being a diesel, lack of compression is your worst enemy. These symptoms sound like a blown head gasket. Check your coolant for signs of oil, and check your oil for signs of coolant. (oil will be milky looking) Also indicative of a head gasket problem is an oil or coolant leak from the engine as well. If you see no evidence of the above, have a compression test done, and it should show up.

Our renault megane scenic which is 1998 keeps not starting sometimes it does and othertimes it just wont start for ages. we got aa out one time and they thought it might of been the key. its getting...

if the red light flashes on the dash its going to be an immobiliser fault, normally it is the key that is at fault, the keys are pricey about £80 plus programmimg, but you can manually override the immobiliser on the early scenics, just pop into your renault dealer and ask for your immobilser code, normally charge a tenner or so, and ask if someone can show you how to put it in.
