check the throttle they get caked up in gunk, and also the flyby wire VDO STEPPER MOTOR inside the black housing on the throttle, give all a good clean out with carb cleaner (throttle a PITA to remove) replace O ring to the top throttle air servo (they leak like hell). had trouble with my megane, no one could find the problem but i did water ingress into the stepper motor case, piched rubber seal so put a bead of silicone on after youve taken it appart.
My dad had a similar problem with his 1999 Megane 1.4. It stalled when it was cold, but ran fine once it had warmed up. We never found out what the problem was though, because we sold it, the problem was intermittent too which didn't help.
same to my coupe dynamique... Car works fine, but it couldn't be moved when it was minus 2C. Im about to go buy new air filter, clean Idle control valve and spray some carburetor cleaner in throttle body.. If i will have same problem again, i will disconnect MAF and see if it works...
usually the throttle gets dirty and it needs to be cleaned or the rpm sensor(something like that). I have the same problem, and to start the engine sometimes i have to use the throttle. It usually appears after using cheaper gas like Petrom 95 and once i've had this problem with Euroluk.
I haven't read all the information here only watched the video I happened to be a renaut technician, the cause to this problem could be many things such as a Camshafts sensor, a TDC sensor, a Temperature sensor also throttle may need cleaning, Get Renault to reprogram the injection computer, One more thing if the throttle needs cleaning it won't show up as a fault on the diagnosis tool
The exact thing is happening to me at the minute! Now thankfully is hasn't happened in a few days now but it is not very reassuring if your a hundred miles away from home. lol Going to try the collant sensor connector! Thanks 4 your help!!
Well, I had the coolant temperature sensor replaced. All was good for a year. Same problem recurred; Renault could find no fault. Removed coolant sensor connector, found green corrosion; brushed, cleaned up and sprayed liberally with WD40 - no problems since.
This is wrong,the sensor for the ECU is actually on a different sensor to the one on the gauge. Whilst this has been rectified and happened to be a CTS the reading on the dash has nothing to do with what the ECU "sees".
Whilst it does behave very similarly to a TDC failure, this problem was finally traced to a faulty coolant temperature guage which was informing the ECU that the coolant was at -20C.

My 1.6 rt would stall from warm or cold if I didn't give it some gas and rev!

If you watch the video, you shall see that the engine is, indeed, warm. QED.

Can you tell me how to remove the coolant sensor, where is it located?, excuse my ignorance?
