HELP! Warning Light - Monitoring Exhaust Gas

[S Garbett]

my bros 1.2 clio mk2 ph1 has just thrown this light on dash:

what is it all about? anybody else had this problem? and how did they fix it??

Cheers Steve

Most likely the lambda sensor, or the cat that need replacing.

 

[S Garbett]

cheers fella, would it be a renault thing or any garage?

 

[Beef-Mc]

I always thought it was emissions problem that would be cleared after 10 clean starts.

 

[S Garbett]

so start it 10 times and it should go?

 

[Beef-Mc]

Yep, should sort it.

 

[S Garbett]

so on off on off

or on leave for 2mins off

mine comes on and off as regular as clockwork - when it was under warrenty had the lambda sensor replaced twice by renault..............im not too bothered about it anymore tbh

 

[f0xy]

mine came on with the DIY decat, my mate reset it with his PC/cable to turn the light off, came back on after 1000miles

 

[S Garbett]

he cant go over 40mph tho

any ideas?

Sounds like its in limp mode, get it on a diagnostic machine, Renault will charge half an hour for that, well worthwhile as it will pin point the faults. Thats a universal warning light, could be any number of things.

Could be upstream or downstream oxygen sensor (before or after cat) had it on my cup, £260 later at renault was sorted! could take it out and clean it up and put it back see if it sorts it, probably need plugging into diagnostic machine
