Evening all

 

Just driving back from work and this red warning light started flashing at me, mainly when I'm slowing down. I havn't got a manual so any help would be appreciated.

cat overheat - usually unburnt fuel getting to exhaust. Check you're getting a spark on all 6...

It's definitely the 'Cat Overheat' light. Basically you're cat/s are getting too hot, this can (normally) be because you've got unburnt fuel going into them. Possible one (or more) of you spark plugs are not firing properly.

This could be a dodgy Coil Pack or the PTU. Check out your Coil Packs visually for splits in the rubber sleeve, and the spark plugs as well. If everything looks OK, see if a friendly member on here would lend you a PTU. Or even if anyone ho owns a ConZult local to you could hook theirs up and give you some advice.

Same light came up on the wifes motor when there was a problem with the AFM, probably made worse by me booting it to try and get it past 50 m.p.h. ! !
