Right since the snowy and cold whether. Two things have been happening.

First one is when i first start the car i normally give her a little acceleration to get the engine going running as you normally would. Lately. When i press the accelerator nothing happens. Its takes a few seconds. Then say if i have the accelorator half pressed it has to build up if you get me???

Second, is i've had it in 4wd (hi) a few times, but when switching back to 2wd the front wheels on the dash just keep flashing. Had it happen for 5 min before they went off. Couldn't tell if it was in or out of 4wd though.

Any suggestions on either?

I noticed last feb in the snow that it could take a little while to drop out of 4wd. Thethrottle thing, dunno, maybe if it is cold the MAF sensor won't let the engine rev. Try the engine warm up switch, that's what it's for :thumbleft:

Regarding the 4WD, whenever i use mine, which isn't often, when i want to dissengage it, i just stop, put the truck in reverse and back up a little and it comes straight out. Not ideal i know, but this procedure is quite common with 4WD vehicles.

As for the throttle, it's operated with a fly by wire, so maybe there's a fault with the signal? :wink:

With the 4wd it says that it can be operated at speeds up to 100kmh. I was driving at the time of turning it back to 2wd and the road i was on had some tight corners and you can't use 4wd or the rear diff locks up (which i find stupid)

my 4wd lights on the dash can flash for a bit,and take a while to go back to 2wd, and i have reversed to disengage it before.
seems to work fine though,...

In mine, to get a good disengage to 2wd while driving, either switch to 2wd just as you shift gear or hold the throttle on to maintain your road speed, then just back right off momentarily as you shift to 2wd to take the torque out the drive train. Will switch straight ver then. Helps if you have the wheels straight, but not essential.

Also, don't be afraid of 4wd, it only needs a lil bit of slip, so as long as its icy then you can run in it to allow the odd slippage to stop wind up, they don't need constant slip. I don't know anyone whose blown theirs up except by driving out a field and not putting it back and driving back to the yard.

well i thought the whole ide of 4wd is to stop it slipping???? I nearly wrote of the thing coming up to a tjunction. Ended up the far side of the road is a ditch with the jeep facing a 90 degree angle to what i was going (facing as if i has turned out onto the t junction).

So i thought it was time to use the 4wd on the thing.

Mate, i did exactly the same thingf in mine last lot of snow. It did a 180, sideways into the field and flipped over, all at under 30mph. Drove out tho :lol: Basically, the school of thought of the japs is who needs permanent 4wd? fair enough, increased fuel economy. however none of them seem to think a centre diff is a good idea as they reckon the only time you need 4wd is off road. In a 170+hp pickup, you need 4wd in aything other than average conditions to fully utilise it! Yet, minus the centre diff, u wind the transfer box up. To avoid this, one or more wheels needs to spin, only a tiny bit, now and again (depends how far it spins each time as to how often) to relieve the torque building up in the drive train. Centre diff would eliminate this and allow you to keep it in 4wd on the road, even in summer. I know if i could, mine would be in 4wd as soon as it was raining relatively heavily, then you can forget about all the power at the back and get on with it, especially when you have no weight in the back.

Just be careful, the laws of physics still apply with 4wd...And the amount of 'quattro' owners I have seen taken by suprise when the 4wd shifts...Actually the Murano did that and nearly had me off the road as I was going ever so slightly to fast on that country lane...And if it was slipping I would have been able to control it, well so I like to think as I am used to it...But it was slipping and then all of a sudden grip kicked in which was unnatural....

Just be careful...

Definitely, but its the opposite for me lol :? Where i'm used to driving land rovers/range rovers, they are all permanent 4wd, so it seems mildly strange to not have that extra grip and different driving dynamics, plus i've never driven anything as nose heavy/rear powerful as the nav.

Haha! Bit like going a step back in the nav almost then with a small engine up front lol! Have you seen the new one? Its got cameras in the sides of the nose under the back of the sidelights which show you the view left and right at junctions, as apparently the nose is so long, you cannot see out on some!! Theyre standard, and HUD is an option! The HUD reads the speed limit signs and displays them on the dash so you know what the limit is. Not done on GPS though, so will even display temporay roadwork speed limits too!

Really? Sweet! Certainly is a huge bit of kit! Looks about the same size as my truck! As an aside, in theory, the mostrous V12 out of the 7 series should fit in a 1 series :twisted:
