Had the same prob with mine.Dont think there is a mil light eliminator out for them yet (there wasnt when i was looking for one)

JamboRS

is it bad to keep runnin the car like this or can he just ignore the light and keep driving it

Car will be fine only thing is if it does develop a fault you wont know because the light is already on.obviously.There was a post some time ago about this & mark shead replied his car is the same & just to live with the light.I had mine in march surley someone has made a mil light eliminator for them now?

gil

JamboRS

If you dont want the light on its the only way round it unfortunetly

i read somewhere that pumaspeed do a gadget to eliminate this maybe?

if i had no cat, i would remove the post cat lambda sensor. that won't help with the light, but if it's not being used effectively you may as well remove it rather than use up it's useful life

Puma speed didnt have anything at the time.But i would be surprised if someone hasnt made one by now as its a common prob

i read this quite recently, might be worth checking again?
