Lol, yes it's had a good thrashing at various times over the past few months - going to get my exhuast man to take a look in the next few days and see if he can move them back behind the CATS

I must say I've never rated additives either, and the fact is my EML went out soon after using Shell V power fuel.
I stuck the cataclean through with some scepticisim, as it was recommended on here somewhere.

Still don't know what to make of my results, but the fact is my EML was coming more and more often over the last 8 months, now is been out for 30 days....

And no...the bulb is not blown...

It's always possible that your issue was caused by contamination of the cat rather than deterioration. Maybe some decent fuel has helped. The monitoring of the cat is obviously borderline, so small changes will affect it - until it gets bad enough to give you a constant orange light.

.. and the Lambda sensors that need relocating are the "post cat" ones which are actually behind the pre-cats (in the elbow of the downpipe) but before the main cats. Relocating them after the main cats gives the main cats an additional opportunity to clean up the exhaust gases and, being a bit more generously sized, the main cats last very well.

Have always run my motors on Shell V Power since it came out.The only other choice I consider is BP Ultimate. Both the Omega's I've had object to any of the other petrols by giving  poorer performance. They do need to adapt to these better fuels 8-)

Also should really mention that my 1st Miggy was a 2000 3.0L MV6 had it for 4 yrs, and my present 1 is a 3.2 Elite and I never have had any EML problems. I also believe in useing Mobil 1 oil,which I change well within the change periods, Could be this backs up Kevin when he says its important to keep your engine exhaust clean.I'm about to have a new S/S exhaust fitted next Wed because VX cant provide an exhaust up to OE quietness spec Wonder if sods law will prevail and I'll be paperclipping like mad :-/ :-/Allthough I do feel confident in the guy's at Lifetime Exhausts.

If you're having a custom exhaust fitted I'd get the Lambdas relocated while you're at it. There are two types of 3.2s - those that have the orange light on, and those that soon will.

Think most probs are the lambdas,Gone now but before it went My 2.0ltr manuel Est was returning 27 local and 31mpg on a run,It had 4 fast and long no stopping for a break of over a 100mls,first run round trip 250mls  33mpg second round trip 280 mls gave a return of 36mpg the best i ever had anyway second trip was to look at the Omega Ive got now   short runs it appears the Lambdas get coated and need a good blast to clean up and give a proper reading.

It was too good to be true..............EML came back on yesterday..

Is there no way to bypass/fool/disconnect the sensors?
My dash now looks silly with a square of black electrical tape stuck on it..

You could always invest in a code restter .. the ELM327 is about £30 but needs a laptop .. the Maxscan is about £80 but is a stand alone piece of kit .. mine now lives in the boot, but since I bought it the lights only come on the once !!!  way back in October !!

Still with Vx charging £70+ to put the light out its already paid for itself really  

[SP_3.2]

Just had a new stainless steel cat back done and reclocated the o2 sensors behind the main cats and light not back on for the past 3-4 days. Most times when i have reset it with my Maxiscan it,s off for a day max.

Will take some pics and post them of the new location and the new system on Friday

So I need a ELM327, Compatability:  OBD2, EOBD, CAN. ELM327 chip (2008 Version 2.0) with a 16 pin plug, and my laptop............is this correct?

Yup 3.2 facelift is ODBDII compliant ... and you have choices ...

Be VERY wary of getting the maxcsan off e-bay.. I did and had to send it back it was a chinese rip-off without the correct cables or handbook !!! so I went to the guys listed above .. I see tehy are showing sold out ATM .. might be worth a phone call

There are also other OBDII readers ... just stick OBDII reader into google and you'll get a lot of hits !! I can't say owt about any except the two I've tried .. and the only reason I haven't sold the ELM327 is at £30 I can afford to keep it "just in case" the GS500 ever goes wrong ..

Interestingly, my orange light has now gone off. I am however getting one fault code for bank 1. When i get 2 fault codes ( bank 1 and 2 ) the orange light comes on. I assume this is so anyway.

Theory for mine is... the pre-cat on bank 1 is on its last legs and is flagging up a fault all the time. The pre-cat on bank 2 is just starting to give out and flagged a fault after an hour of heavy driving followed by being sat in traffic and subsequntly heating up. This also occured after filling up with poor quality fuel in the middle of no where at a local garage.

Il try filling with v-power or another top brand fuel and see if it re-occurs. Seems to me like the cats are struggling when theyve had a lot of work to do, followed by being heated up.

[Entwood]

0420 & 0430 codes on a 3.2 are common .. and it does NOT mean the cats are worn out ... it is just one of those things .. the sensor is between the pre-cats and main cat .. and just tells lies    Seriously .. it usually happens with poor fuel/short trips IMHO .. so a decent Italian tune-up can sometimes clean the system and the light goes out ...  or rest as said with cheapo tech11.

When I first got the 3.2 after having the 2.5 .. the guys here told me its not IF the codes come up .. its WHEN .... and so far they have been 100% correct

Is this applicable to the 2.2 facelift as well? I get the emissions light very occasionally and would love to know whats causing it...

Thats exactly what Im looking at......cheers..

Now, where do I find the kit to re-programme the ECU to adjust the sensor limits, and re-map to get 300bhp...
