doctorjohn Posted September 28, 2015 Share Posted September 28, 2015 Advice to a new owner please re reducing 'high' CO2 emissions: Recently acquired WRX 2.0 turbo (320bhp) failed MOT due to high CO2 readings. MOT tester (decent bloke) looked underneath and said there seemed to be a shortfall in the cat department and this was the likely reason. Any inexpensive fixes on this one?

Scoobyghost Posted September 28, 2015 Share Posted September 28, 2015 You could try to borrow a cat if you can find one. I still have my cat stored up just in case. Or you could find a friendly mot tester [emoji12] Quote Link to comment Share on other sites More sharing options...
doctorjohn Posted September 28, 2015 Author Share Posted September 28, 2015 Good thought, thanks, I suppose a second-hand cat would be a risk? Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted September 28, 2015 Share Posted September 28, 2015 It is a risk. If you were local I'd let you borrow mine. A second hand cat may just be up for sale because they owner decatted and be fully working. Anything second hand is risky. Quote Link to comment Share on other sites More sharing options...
Jimmymac101 Posted September 29, 2015 Share Posted September 29, 2015 just be thankful you dont own a VW haha On a serious note .... when was the last time it had a decent service inc spark plugs - dizzy - ht leads - oil - oil filter - air filter ? worth doing that as every little helps being that its 320bhp im asuming its mapped ? it could be a mapping issue maybe James Quote Link to comment Share on other sites More sharing options...
doctorjohn Posted September 29, 2015 Author Share Posted September 29, 2015 Seems VW have found the way round the high emissions problem James, maybe I could borrow the offending part! Good point about having the basic service items all in good nick - unfortunately they all are, so no scope for any benefit there. Yep, it's mapped and quite a flier so I'm reluctant to meddle with the mapping. Maybe a high flow sports cat (= wallet pain of course) would resolve it with minimum affect on performance?

Scoobyghost Posted September 29, 2015 Share Posted September 29, 2015 It would need to be mapped to cater for the sports cat. 1 Quote Link to comment Share on other sites More sharing options...
