Howdo kids, not been around these parts for a while, but I just know someone out there knows chapter and verse on this one....
I run a fleet of vehicles (9 bikes and 4 cars) - one of the cars is leased to us and changed every 3 months or so. At the end of July we got a new one, which was petrol when all the others have been diesel. Day 2 with a brand new car, and a muppet puts diesel in it, gets about 200 yards before it craps out on him. Its been drained and flushed through, runs fine now, but the engine warning light will not stay off, code P0420 Catalyst System Efficiency Below Threshold (Bank 1) is recorded. Its had Cataclean through it (3 bottles), and had a cat regen program run today - but the code returns.
What else can I try / get done - is my only option going to be a new catalyst?
Any info muchly appreciated!!
