The foc-u font of all knowledge - misfuelling cockups.... - richfzs - 18-08-16
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!!

I would get the live data checked before replacing the cat, the diesel my have affected one of the oxygen sensors causing the code, is there any other codes? if you do a general check of that code it mentions the cat being clogged by oil, I dunno if the diesel would do the same, we had an old style corsa come in with the check engine light on, someone told us to remove the oxygen sensors an give them a good rub/clean on a wire brush then dip them in brake fluid, that did the trick (not that I'm saying that would work in this case). What type of car is it, try a quick google with the code and make / model.

That's the only code showing. Its on a 2016 Mokka 1.6

Didn't think you could get a diesel nozzle in a petrol filler cap?
Re: The foc-u font of all knowledge - misfuelling cockups.... - Albert Herring - 19-08-16
Other way round, IIRC (since petrol kills diesels far more effectively/expensively than vice versa)
You can certainly get one in the filler cap of an Aprilia Pegaso, anyway. Ahem.

You can wrong fuel a bike as the opening is so big, but in a car the diesel nozzle is too big to fit in the petrol filler hole.

There is that - I've thought for a while that was no longer such a thing as a "bad" car, but the Mokka has proved me wrong. It's just bloody dreadful, in just about every way. With apologies to anyone who has bought one - but why anyone would spend their own money on it is beyond me.

No, you can't, the guy must have had it balanced delicately across the top of the filler tube, and been standing well to the side to avoid the spray!

I would change the Pre-cat Lambda sensors first. It is the most likely cause of the problem as they do not like raw diesel :eek

You shouldn't be able to get a derv nozzle into a petrol car. The muppet must have been standing there ages to get a decent amount into the tank.

Like I said Bob, he must have had it carefully balanced at the opening, and avoided the back spray. All while ignoring the sticker on the inside of the filler that says "Nae fckin diesel, you dickhead".
