simonc wrote:@wurlycorner Good morning Iain and thanks for the info. That orange one you show is now permanently on. The last grease monkey I went to says someone has removed a plug and it's an "emissions" warning. He says it's nowt to worry about but I don't believe him.
If it's permanently on now (i.e. from the moment you start the car) then he could well be right. This is easy to check.
Have a look underneath the car where the cat is. There's a sensor on the side of the cat at the back - that's the cat over-temp sensor. There's a grey plug on the drivers side bulhead (under the car) that it plugs into.
Check to see if it's plugged in. If it's unplugged or the wire is broken/damaged etc. then that is why this light would be on.
This is photo of the connector;
NB: As standard it doesn't have that red crimp on the end! That end of the wire should be connected to the sensor on the cat instead... You can just see where the sensor is on this photo, behind the right hand shiny nut at the back of the cat - that's where the wire should actually run to
Because the sensor snapped on Lisa's, to stop the light coming on I cut the wire and put the red crimp on the end and bolted it to the chassis (connecting the wire to ground turns the light off) as suggested by some of the genius's on here
This is the sensor/wire before it snapped;
I think there's some more photo's
here too
Now to add to the problem, on Monday on the way down to Singapore it was the red "Engine Warning Light" that was flickering, then going out, then coming on, then flickering, then staying on, then going off again.
Both worry me Iain but more so the red one as (in my limited knowledge) that's the one that says "your engine's about to grenade".
You don't want either of them on tbh, but don't panic... (yet, anyway - we need more info before starting to panic!)
Check the cat temperature sensor connection out like I said above and see how that looks.
As for the red CEL, if that light is on, then it should have stored a code.
Pull the fault codes from the engine ECU and report back what codes it gives you, then we can go from there
How to check the codes if you don't know, is
here
The connector is tucked out of sight behind the back of the centre console panel by the clutch foot rest;
View if the centre console had been removed (you don't need to do this, but so you know where it is);
If it's not been used before, the connector is plugged into that holder. Unplug it and it will hang free into the footwell so you can bridge it.
Ignore the grey connector, that's something else.
If you try this and get no codes, it may be a poor connection across the connector, try adjusting the paperclip/using a different paperclip/using a bit of wire instead.
so as long as it fits and isn't porous, it shouldn't particularly cause any major problems with how the car runs.
