I'm still trying to get an RT4 working properly in my 2011 X7... it's just little niggles that I need to iron out. I know when I bought my very first RT4 for my C4, when I received it is was not configured anything like I expected - a C5 specific config and I ended up having to wipe the HDD and reinstall from scratch. If anyone has an X7 with an RT4, and feel comfortable doing so - would they be happy to create an image of the HDD and upload it so I can restore it and see if that gives me the correct config?

Bit of a strange one some of you might think. I've got a 2011 C5 X7 with the RNEG satnav, but I prefer the older RT4 head unit. (Yes, I would love an RT6 but I have the RT4 sat here). I know older X7's did come with the RT4 but this was quickly replaced by the RNEG. I've fitted the unit and coded it up, but there are a few quirks... 1) The screen in the centre of the speedo displays zone not mapped. I've had a look around and it seems for RT6 installs this can be enabled. I have no idea if the RT4 is even capable of outputting the correct info, as I believe cars that came with the RT4 had the older display in the speedo - I've no idea if this even displayed the mapping info. 2) There's no control over screen brightness. The rest of the cars panels can still be controlled, but not the sat nav screen. 3) Possibly related to the above, the map doesn't change between day/night mode when the headlights come on. I might be clutching at straws here, but does anyone have any experience with this? I really would love to whack an RT6 in, but I can't justify the cost as I'd need the screen too - so I'm going to have a go with this. If anyone is willing to sell one cheap I might be interested though!

Well, I have picked up the wagon and I've got to say I'm very impressed so far! A much, much smoother ride than the C4, and it's looking much better on the fuel consumption as well. I took a pretty steady (but still above 60mph) journey on the way home and the car ended up showing a total fuel range of 1050 miles possible on one tank. Still getting used to the myway system - coming from the RT4 I have a habit of going to the knob to turn the volume down. Only thing that's bothering me is the surround around the radio and aircon control panel - it's peeling in areas. Fortunately its black plastic underneath so not too easy to notice, but just wondered if it's a common issue? If not i'll try grab a replacement.

Sorry, I forgot to mention the engine in all the fuss. I decided to limit my searches to the 2.0HDi, 160 model. Too many horror stories of 1.6's not being looked after. So, after having a look at the manual model (2011/60, 2.0HDi 160) I made an offer and it looks like I'll be joining the club! In my opinion, it looks like I've got it for quite a good price (private seller) which will go towards the cambelt change, possibly eolys top up and tidying the interior up. I also think a worthwhile warranty may be a decent shout for this steering oil pipe. Glad to share more details if people are interested.

So the auto I went to see yesterday is in really good nick. Eolys was refilled recently + cambelt done. High level stop light was crack and a couple of small chips in the windscreen really was all that was wrong. Only concern was showing 33mpg over the last 2000 miles... Can anyone with an auto relate? I usually get 47 out of the VTS so that's my yardstick. There's a manual one a bit further away. I know it's not in as good condition externally, cambelt hasn't been done and the eolys is an unknown. It's also got a couple less toys. The big one though is at its last service they found it needs a new power steering cooler/pipe. That work hasn't been done yet, but is a diagnosis of that indicative of the steering rack? This is a 2011/60 model though - does it affect later cars?

Thanks for the tip on the steering rack - I'd read it but didn't realise it really does mean that much to sort out. With the LED DRL lights, I liked how the strip went all the way up the side but that's really just a nice to have feature. There was no main reason for going for an auto - I wanted to avoid another clutch and DMF change and I guess at the mileages I'm looking at there might be a bill shortly on a manual if it's been hammered. The auto would be nice to commute in mainly, as I'll probably keep the VTS for "proper" driving. No intentions of towing anything. Any cars i'm looking at I'm making sure the timing belt et al. have been done. Although the DPF may be one I'll have to take the hit on. A lot of people with the C4 take them off and pressure wash them to extend their life... guessing the same would apply here unless access is much worse?

Thanks for that, another question that I've not seen much mention of... The LED DRL headlights. It looks like they feature from late 2010 models? Maybe early 11. Does anyone know if you get the headlamps you can fit them to earlier mk3s and they'll work?

Hi all, I'm looking at a couple of C5s, for the same reason I have had several C4s in the past - a lot of car for the money. Currently on a 2.0HDi C4 (138) which has just had a new clutch + dmf. I've done a fair bit of reading but just hoping for a few people's input on this. I'd quite like the idea of an exclusive as I believe there are few suspension issues but they're pretty rare. I've got the directional xenon's on the C4 which really are useful, but on the C5 mk3 they seem even rarer. I'd buy this as a steady cruiser, to commute to work and back, and occasionally visit family 200 miles away. I know on the C4, the 1.6HDi is a good engine but it had to be looked after properly. But is it underpowered on the bigger C5? And is the 160 recommended over the 138 2.0 lump? I'm familiar with the DPF on my C4 - is it the same system or has it been tweaked? Something my C4 must use is the recommended Total oil I've found. Anything else will kill the engine at the end of a regen (yup, weird!). Now the autobox (proper auto) would be completely new to me if I get one, and I'm not familiar with the C4 ones either. What sort of maintenance do they need? Any comments on reliability? Not too fussed about the higher tax although it does hurt! I do have a C5 in mind (non-exclusive), but it's fairly high mileage. It appears to have been looked after but are there any flags on the C5 once it gets over 120000? Any tips to look for when I check the car in person? I've got diagbox so I intend to check what history I can through that, but obviously it will only say what's been done in the past that needed diagbox connecting.
