What is 6th gear for?

I have been running it on Mobil diesel since I got it, would there be any benefit do you think in trying another brand of fuel ? . . .

I'm quite surprised you haven't done so already. Are you filling at the same service station all the time?

I'd certainly suggest trying a different brands particularly from a place were the stocks are replenished frequently. If your DPF still plays up, then you certainly have a basis from which to bring it to the attention of your service dealer.

I have been filling at the same servo near home since new, it's a very busy one and stocks would be replenished each week I would imagine. I still think there could be an issue with the DPF but the dealer basically won't do a thing about it unless it throws an error code. The only other way that I might get their attention would be to have it put straight onto the back of a truck when it starts it regen process and send it to them. The trouble with that is my nearest dealer is 80 k's away and I'm already not overly keen on the service dept. as it is. I guess if it eventually *****$ itself then they'll know what the problem is and will be able to fix it, hopefully

I've also noticed if I change High, like around 4000, then crusing at 100kmh in 6th puts my rpm around 2000.
though if I change early (automatic mode ) then 100kmh in 6th gives about 1500rpm
