I still get the 02 fault. i might have a small exhaust blow. i had a leak in the connection to the rear muffler but i have screwed around with it, replaced rubber hanging thingys and was resonably satisfyed with the result when tightening the clamp, but i bought a new clamp and shold replace it. there is a seal there, looks like copper, shold i replace it or is it enough to heat/glow it up? il take a good second look at it to be sure.
I guess there is no way around a diagnose scan.

Re: MIL Light illuminated
Temps look OK. You can't really tell anything from a snapshot of dynamic O2 data. Was the upstream sensor voltage rising and falling and the 2nd fairly stable as that's what you should see?

Re: MIL Light illuminated
What about the permanent error, fuel injection- coherance?

Re: MIL Light illuminated
I explained that earlier- Fuel trim, but you need to find whats causing it. Long shot, but have you checked cam timing? If it's a tooth out it can cause this.
BTW- Shouldn't have failed on EML / MIL

... I know of at least two others that failed because of that .. might be new instructions to go with new MOT training. But if that light is one it generally means an engine issue.Family Fleet: ex-Cayman Green 206 CC 2.0 LE, Indigo Blue 206 1.4 HDi Hatchback, Subaru BRZ Auto, Alfa Romeo MiTo

Re: MIL Light illuminated
Timingbelt was replaced recently, but i had the same issue before i had this done(by a pro) so i dont think the timing is the culprit.

Re: MIL Light illuminated
AFAIK MIL for anything other than EML is a fail, but EML only is an advisory. I will have to check as it may have recently changed.gazza82 wrote:Think you do now Col ...Capncol wrote:BTW- Shouldn't have failed on EML / MIL
