Megane Check Injection ! Megane 225 RS

[S.Chow]

Had my Megane 225 for a while now & got it mapped by RS four ashes, happy with the mapping and the way the car came out ! Drove it for a while then parked it up as I had my FR, FR now gone I got back into the Megane but whenever I go to put my foot down and accelerate hard the check injection light comes on! Boost sensor in front of the battery has been changed, 630cc injectors have been fitted and spark plugs have also been changed. Any idea what it could be ? Thanks

Did you fit the 630s post map? Or was it already on 630s?

 

[S.Chow]

Had them fitted the day of mapping

Needs plugging in and scanning with clip.

As above. Its guesswork otherwise

As above. Its guesswork otherwise

as Andy says it’s just guess work without Renault diagnostics
From what I’ve picked up over the years it seems Renaults check injection message is just a generic code for a engine sensor fault
Or in simple language don’t mess about changing things with our cars because we don’t want you changing things or tuning them Without renaults say so Lol
I used to get a check engine message for my 200t all the time and when you checked with anycode reader apart from renaults it would show no faults
If you used renaults gear it would show gearbox overheat fault which in my book has nothing to do with a cars injection system
even with Renault looking at the faults the car was brand new in 2012/13 and they new fkcu all about the 200t and it took them ages to bring out a gearbox update which I will say did sort out the fault or in my head it was a update to sort out a fcku up with their original gearbox parameters
Renault Was away ahead of others with a great little car in 2012/2013 but they put the car out to soon with lots of little niggles
Get yourself a Renault clip from ripoffbay and check the fault codes yourself
Good luck and hope it’s a easy fix

Hi alright lads, so I got it checked out and it came back with the following fault codes, DF049 Refrigerant Sensor, DF079 Motorised Throttle Unit Control, non compliance with pollution standards, DF004 Turbocharing pressure memory sensor, DF026 Front R/H wheel speed active circuit open circuit or short circuit to earth, DF063 Wheel speed coherence memory, DF006 Front left hand wheel active speed sensor circuit, DF011 Rain/Luminosity sensor, DF010 combined stalk under steering wheel, DF027 external temperature sensor, DF026 Sunshine sensor, short circuit to earth. That’s a whole lot more than I expected, reckon it’s a faulty earthing or something else, anybody else came across any of these ?
