September 28, 201510 yr 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?
September 28, 201510 yr 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]
September 28, 201510 yr 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.
September 29, 201510 yr 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
September 29, 201510 yr Author 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?
September 29, 201510 yr My sports cat failed 1st time as not hot enough, however that was on jap map and was over fueling which wouldn't of helped
