The important thing to remember is that jump leads are NOT capable of carrying enough current to drive a starter motor under load. ....

I reckon mine are

....
Mkaes no difference if it is running or not

Give me your theory then  I can't see a difference where you connect the earth,  the terminal, block or anywhere else, still the same potential as far as I can see.  :-/ :-/

So you don't see an issue with creating sparks near explosive gases then - thats why the last connection is made AWAY from the battery

I couldn't agree more,     however, I wonder if the same still holds true for the modern day sealed batteries.  :-/

You did connect it O.K but it's better to keep engine running.
specially if the battery is weak.

Forgot to say, bring it over at some point, and we'll clear it out. Need to revisit your telematics at some point as well...

Connected jump leads from my Omega battery to the RR, got it started. Then moved on to the Sprinter. Sprinter took a few attempts to start, I think that's where my battery wasn't too happy.
I wasn't overly concerned, but something must have triggered the fault code, and I was wondering whether it needs to just be left or I need to attempt to do something about it.

You need to learn how to jump start cars matey!

Meaning what? The op has not mentioned anything where you could judge him doing something wrong?

Quite the contary.

The correct method requires the supplying vehicle to be running with some revs on for a few mins to get a bit of juice into the flat battery....then and only then should a start be attempted.

If this had not been done then the flat vehicle could pull a battery low enough to cause said faults codes (and it has to go mega low!).

down to 7.9v iirc

Precisely ...ive always done it this way - 1) connect jump leads 2) leave supply motor running, with few revs (2/2.5 k) for few mins 3) attempt starting of the 2ndary vehilce.   - success is forthcoming

TIS states 10V for 180 seconds.....

Mark, I do indeed need to learn how to do it properly.
I connected the negative from my Omega to the neg on the RR, then positive from mine to corresponding on RR. I did rev mine to 2k for about 40 seconds then turned the RR ignition on but didn't attempt to start it. With the ignition on; the radio, climate control and air suspension all started to kick in, after turning them off I left mine idling for another 40 seconds then attempted to start the RR.
Sprinter, same sort of thing...but someone came over to help. He attempted to start the Sprinter whilst I was revving mine, it wouldn't start...but he must have tried another 4 or 5 times in quick sucession before he heard me tell him to leave it.
But, agreed I do need to learn properly how to do it.

And mine... I've jump started lorries with mine 

Oh... And that was off an Astra Van (Only one of the 2 12V batteries was flat )

Thanks TB. I've got Mrs TB's cup to return aswell. I was speaking to Andy at Newent about it, would it be possible to just cut the airbag wire to the telematics unit? Also we've got to think about those other bits. I've paid them for them, just waiting for the go ahead to collect. But hopefully it'll be very soon. Sorry it's taken so long.

Cutting the wire is a possibility.  I think, due to amount of stripping, further investigation if that fails probably means stripping out the airbag ECU, which is probably going to be a PITA.

I can see it now, TB consulting TIS, Josh with the wire cutters debating which Yellow wire to snip and Andy standing out of range of the Airbag!

Reckon if the Airbag Trigger line is snipped the easiest location would be to disconnect the Telematics plug and snip as close as possible to there, should also be easier to identify.
