Thanks DMRR.

As for the software update, does that mean that the EMS warning does not mean the car is about to self destruct (I have since cleared the fault with the IID tool, just like the MD did when it first came on 3 weeks ago, this latest EMS 'lean' warning being the third warning, the first two being 'too rich' warnings)?

ps.. the car is running brilliantly/ silky smooth after 4 days of the BG44K running through the system and still going through. That's not an over statement either.

Me and my business partner bought our 4.2's at the same time, his suffered from this issue early on and was 'updated', mine did it after about 50,000 miles and again, it was updated. I seem to recall it was something to do with fuel grade, are you using standard fuel or the 'super' fuel? I was advised to stick with 95 RON (I think that was it as it was a while ago). Land Rover Addict

Thanks again DMRR.

We only ever put Shell V Power Nitro+ in the car as I thought that was the best for a 'high performance' engine?

I think the RON rating for that is too high - it is ok to run on it now and again but the main diet should be standard unleaded, that's what the UK spec ECU is expecting, 95 RON  Land Rover Addict

There you are then and I thought liquid gold was the way to do it.

I shall revert to standard unleaded and see how we go!

Can't help thinking this all coincides with the MD recently having had the engine out though.

Standard in the UK being premium (95), standard everywhere else is 91...... and called 'unleaded' - nightmare!!! Land Rover Addict

Interesting that ^

Seems that the Ron ratings Vary a lot worldwide There is nothing that can't be fixed with a hammer😜😜

It suggests that the SC doesn't need tank after tank of 99 RON + of Shell VPower Nitro +

Regular shell fuel save unleaded should do it then, wonder if it is the same for disesel There is nothing that can't be fixed with a hammer😜😜

4 weeks since putting BG in the tank and 3 weeks since converting from Shell V Power Nitro+ to Shell Save (standard) unleaded and the system too rich, system too lean warnings have gone.

Shhh

I got a gallon of this stuff for my Diesel but kept forgetting to put it in, didnt seem to make any difference for me. I only bought it after reading a thread on here, I just get Tescos cheapest now just as I have been doing for the last 20 odd years with no problem - just lucky I guess  Geoff

I only tried BG after researching around the rich and lean warnings, hoping it might banish the warnings along with a MAF sensor clean and changing to standard fuel.
