The Mégane II Owners' Club

i have 04plate 1.6 16vvt i push the button it turns over but takes bout 5/6 sec to start same if its hot or cold once its started it drive flat
i had the tdc sensor and loom changed the cam sensor, dehaser ,timing belt kit, water pump and a service with sparks and filters replaced also had software update but still the same the car only has 29k on the clock
its been on renault computer nothing flags up
anyone know what might be wrong with it as it starting to get very pricey

Has the throttle body been cleaned?

yes it was 1 of the 1st thing to be done with the tdc sensor

How about the ignition coils?

thanks for that
anyone esle have any idea

what i have noticed when its very cold on the 1st start it starts 1st time but then after that if i turn off and start again the problems back

Ok. Next idea. When you cleaned the throttle body did you disconnect the battery and then go through the re-learning procedure when reconnected?

Whats the state of your battery like
meganes do like lots of power and if its just not there it will take a bit to start

just a thought

cant answer as the garage as done all the work

the battery is good new

does anyone think it could be the fuel pump

If you switch on the ignition you should hear it whine then stop for 1 - 2 seconds. If you can't hear anything investigate. If it runs continuously, its in limp home mode, so investigate that avenue.
