Title: Emission Light
Post by: Roger Flo on 11 December 2011, 14:59:04: Hi all,
My 3.2 Elite has developed a fault, indicated on the emission light - it appears to stay on permanently orange.
From reading the comments on the forum I need to find someone local to me with a code reader to give me a clue on solving the problem, I am located in Warsash Southampton and travel regularly through Hampshire so can anyone help

My EML came on other day, more o2 sensor codes :(

You had the sensors moved?

Mine have been, should fix it :-\

Post by: Dave DND on 11 December 2011, 15:41:39: Not sure if it adds weight to any argument, but just an observation on emission lights and fault codes from Lamda sensors.

We have a few VW`s here, and if run using Morrsions, ESSO or any cheap supermarket fuel, the EML lights will come on after two tankfulls have been used. If we use JET, Shell or Texaco, the lights will extinguish.

We started monitoring it after we kept runing up bills on replacing Lambda probes, and we reckoned it coudl be down to the way fuel additives (or not) were leaving deposits behind. Never had any emissions problems since, and would always advise a coupld of tanks of good fuel before reaching for the wallet and a new sensor.

Post by: Roger Flo on 11 December 2011, 15:45:08: Hi All,
The only thing that may have caused a change recently, was the recent MOT work which entailed dropping down of the exhaust & propshaft to fit complete new handbrake cable. Maybe the oxygen sensor got disturbed, but that work was completed a week ago and the light has only just come on.
Perhaps I will contact Kevin Wood as I am in Alton on Wednesday.
Regards

Pre LPG, and for starting and when I run out of gas, both mine run virtually exclusively on Asda cheapo 95ron 128.7p stuff

Post by: Dave DND on 11 December 2011, 16:48:39: Can`t comment on ASDA, we don`t have their pumps around here.

Many of the supermarkets share the fuels though !!

Post by: Roger Flo on 13 December 2011, 10:06:26: Hi All,
Thanks for your suggestions responses to my question.
I have now carried out the pedal trick and the code is 0420 which indicates that the catalyst System Efficiency Below Threshold (Bank 1).
Does that mean a new sensor, or a new catylitic converter or does the system need re-setting/re-calibrating?
I did use some fuel from a garage that was in the process of being refurbished so maybe their storage tanks were low and the fuel could have been dodgy?
Regards

Post by: tunnie on 13 December 2011, 10:10:24: standard issue on 3.2's the pre-cats fail, the sensors need relocating :)
Title: Re: Emission Light
Post by: Kevin Wood on 13 December 2011, 11:27:18: Yes, that code can safely be ignored on a 3.2. If the orange light gets on your wick, the post-cat Lambda sensors can be moved to behind the main cats, as stated.

If it's only just popped up it might well disappear again after a couple of tanks of fuel.
Title: Re: Emission Light
Post by: Roger Flo on 13 December 2011, 12:30:36: Thanks to all for the advice
I shall try and ignore the light and use some of the higher grade fuel for a couple of tankfulls to see if the light dissappears as Kevin Wood has suggested.
Kevin - ignore the pm that I have sent.
Assume this matter now closed.
Thanks again
Roger

Post by: Roger Flo on 16 December 2011, 12:54:52: Hi All,
Just to let you know three days of 97 octane fuel and the light has dissappeared Whoopie!!!!

Post by: Dave DND on 16 December 2011, 13:14:45: Thought it might -

Its amazing how many stories of Lamba sensors, replacement parts, changing and relocating parts are on the net.

And virtually every forum I am on where this is discussed, comes down to the same old thing.

Crap supermarket fuel !!
