I bought the Cataclean in the hope that I will clean the catalyst and remove the obd error p0420. After the Cataclean engine works nicer, but the fault is still present Transparent fluid (CataClean) poured into the fuel tank. After pouring, drive the car for about 15 minutes at 3000 rpm. I've been driving for 30 minutes, but error 0420 has also come up after manual erasing again

I always put a bottle of this in the tank prior to the dreaded MOT and once again got a pass with no advisories, not bad for an old diesel BMW with 170,000 miles on the clock. Can't say for certain if it would have passed without it but for a few quid it's not worth the risk. I would add that the engine does seem alot smoother and little or no smoke coming from the exhaust so overall well pleased.
