Hi all-still have this p0420 code- emission light shenanigans at the back of my mind :roll: -would Cataclean help by cleaning out my cat, or should I go with BMW's petrol additive?-thoughts anyone please-thanks.
 
Why BMW,s additive ?
Have you not tried out any similar products already ? Forte would be my pick off them all http://www.amazon.co.uk/Forte-Lubricants-Specialist-Injector-Cleaner/dp/B0035PRJRY/ref=sr_1_4?ie=UTF8&qid=1397890210&sr=8-4&keywords=forte+fuel
Or trade the car for E89 :oops:
 
I use archoil additives. I have also tried bg44k for a once a year clean.
I can't say whether it will get rid of the error code but it's worth a try. failing that, maybe one of the sensors maybe duff.
 
I thought of Cataclean as its for catalytic converters, but thought of BMW's as its 'designed' specially for their engines.
 
Go onto powerenhancers web site and look at the different products. There is also a review/customers comments section to see what people think about the additives.
I've used both bg44k and archoil on various cars and bikes with good results and no adverse effects.
