2X CATACLEAN Petrol Fuel and Exhaust System Cleaner 500ml

It's really worked! My P0420 error code + engine light has gone! 1) Make sure your tank is at 1/4 bar left. 2) Fill it in 3) Drives for 30 mins / 20 miles 4) Rev your engine to 4k-5k RPM while driving 5) Refuel your car 6) Your done!

CATACLEAN Diesel Fuel and Exhaust System Cleaner 500ml

Used this product previously not sure it did any good though, bought this lot in good faith in the hope my vehicle passed the emissions test during the MoT stage. Maybe a coincidence but the next day the EGR valve started to play up??? I gave this product 3 star rating as a middle of the road assessment due to a lack of knowledge to its efficacy at this time.
