1. Diff lock is nice to have, but not essential, if you find a car that is otherwise right I would not pass over it on the off chance that one with it will come along. Your main limiting factor will be tyres, my 322s had either Goodyear MT/R or Duratrac in 255/55R19 for winter. Duratracs are the LR homologated tyre now, the MT/R is no longer available in that size. Duratrac has lower speed rating.

2- mine is a September 2009 MY2010 3.6TDV8 and I’m not aware of it having a DPF.

The only times my 4.4 TDV8 annoyingly changes down is in undulating terrain using cruise control at 100 kph without having selected manual mode on the gearbox or if travelling only just fast enough to be in 8th then suddenly booting it, which can cause the gearbox to drop up to 3 gears depending on how much boot. For normal overtaking I tend to pre-select 7th (up-shift to force temporary 8th manual then down-shift to 7th) then boot it fairly heavily, although the g/box then wont drop lower if I decide that I'd like more. For brisk overtaking just floor it then up-shift rapidly as the urgency diminishes. |

I’m still getting my head round the fact an HGV has kick down. I’ve never driven one, but want a go more than ever now 😀

I've had both 3.6 and 4.4, the latter being an L405, but I think the 8 speed box has very similar characteristics on both models. If I had to choose now i've had both there would be no comparison, the 4.4 is more powerful, more economical, and the 8 speed box is a dream. That said, before the change when I'd not missed what i'd not had, I swore by the 3.6 and did many happy miles in it, thousands of them towing a twin axle caravan all over the UK, France and Germany. My own view is they get better as they get newer. Hope you enjoy which ever you choose. |

thanks guys, appreciate all the advice. Good to know about the oil coolers
I believe some companies have the kickdown and manual mode removed to safe fuel and ensure their drivers truly are in the way of everyone *cough - supermarkets - cough* tippers is where the fun is at, fully freighted, usually on pretty average kit, often up hill and down dale. The truck i had for the last year and a half was a rare for a 65 plate scania R490 with a manual gearbox, it was a nice thing, even if it did have the wrong axles, lovely aggregate walking floor trailer too. I always wanted a go on one of the latest and greatest volvos, which you can now spec a dual clutch gearbox on, perfect, i don't know why this hadn't been done before. imagine how much time and fuel a lorry wastes waiting for that giant turbo to spool up after every slow, automated single clutch manual gearchange, the dual clutch would fix all that! |

They do indeed, but then the on board datalogging grasses you up to an irritating little man called a driver trainer who only drives a desk. You also need to brake as is you have an eggshell between your boot & the brake pedal or go over 2,000 RPM even for a second. No wonder they suffer from glazed discs & DPF/regen issues. 2003 Range Rover Vogue TD6 |

Thanks again all, very helpful, I think i've decided that the 4.4 diesel is the way to go, unless i find that magic low mile pre facelift 3.6 for cheap.
I was lucky i only ever worked for tipper and/or agri companies, i dont think i could deal with that sort of thing. That said, I miss it, and seeing how the latest scanias seem to often be ordered with more power and tag axles, I definitely get the longing when im out and about, but i moved on to a job with, more money, less hours and more time at home, i'd be silly to go back to being at the traffic commissioners mercy. |

All true, but it's worth it in fuel savings and you can have a handy app now as well! ![]() MY19 SDV8 Autobiography - Sold |

It's useful on my drive when I have to get past where my D2 has been marking its territory!
