I really like the colour :) It's nice to see something other than black, grey or silver on the roads.

I thought the chassis underneath was the E91 (touring)?  According to wikipedia etc anyway.

Either way it's a very nimble and smooth riding little thing with lots of character.  Could do with a tad more refinement in the engine and gearbox but I guess that would detract from its charm. 

And even with the naff plastics in the dash it rattles and squeaks less than the E70 and that's in a different market segment.   :noexpression:

Let us know if the other niggle's start to work after the new battery.
The car could have been telling you in it's own way it wanted a new battery for a long time but you didn't know.

Will do - it's quite possible that it's not been right for some time as you say and ancillary "weirdness" that I just assumed was normal for the car was its way of telling me.  It's in on Tuesday morning for the new one so let's see......

If the battery (or alternator) had failed there should be other signs.
Also explains the weird recent phenomena where when getting in the car the sat nav split screen would always reset to "current position", the climate would change to a lower temp and turn off auto, and steering wheel would forget to come out into position etc etc.
Probably should have mentioned those...  :D

Ha, well to be fair the car has done these since day 1 - that's a full year. I'd just gotten used to the amnesiac steering wheel and split screen thing. Climate was a new one but I've had other issues with that recently meaning a new HVAC control unit was needed. Searches on here showed others with the same issues so it just felt like one of the cars quirks. Never an issue starting though - I'd have thought with the grunt required to start that would have suffered first rather than little electronic gizmos in the car? Like slow cranking or something to give the game away?
Every time in previous cars I've flattened my own battery or pushed it a bit I've got back in and tried to start it with a chug....chug.....chug so it was obvious the battery wasn't up to the job.

The night before this thing died completely it fired into life the same as it ever has. Turning over nice and quick. Ho hum. Lesson learned.

After looking for a possible replacement for her leased Q3, which TBH I never got on with (Playstation levels of driving feel, naff interior, very average economy considering the power, AdBlue, poor Audi MMI etc) we decided an X1 would be a good replacement as an "owned" car. 

We ended up with a BMW AUC 2011 plate 2.0 Xdrive SE auto in Vermillion Red which I quite like - it's like a burgundy sort of colour and a little bit boudoir :).   What got me though are the obvious comparisons made with the E70 as they are clearly of the same mindset but feel very different for obvious reasons.  And it was a nice opportunity to sample the older 6 speed box as I've only driven BMW manuals (which I loathe) and the 8 spd ZF in mine.

Firstly the gearbox is the aforementioned 6 speed auto, not the 8 as in my E70.  Very different in how it behaves.  Where the 8 sometimes feels like it can't quite make its mind up as to what gear it's in (especially when cold) the 6 plumps for a gear which tends to be on the revvier side and sticks with it much more.  Changes aren't as smooth but it feels like a far less fussy unit, for want of a better way of describing it.  It's also quite keen to kick down even when warmed up whereas the 8 will sometimes need more of a shove on the throttle for it to realise a change in ratio is needed.  However at all other times, for me, the 8 speed unit is far better.  Smoother changes, less of a feel like it's "slipping" at times in order to keep you in the power band (more ratios to play with) and I have flappies :)

The dash is very similar to that in the E70, just like it's been on a hot wash.  And I have to say some of the plastics especially lower down (like steering column shroud/ trim) are just plain shoddy.  Very hard and cheap feeling.  However, despite this none of it creaks, rattles and groans like the E70 interior which has always bugged me for a car of its class.  It has nav so an iDrive screen in the middle of the dash however this is smaller than that in the E70 and has a bigger shroud to fill some of the space.  Feels like when you used to watch widescreen movies on a normal telly with the black lines, except at either side instead of top and bottom.  However it does feel far more responsive than the iDrive in my E70 - not sure why this would be?  Less features perhaps (she has no DAB for example)?   Definite shortage of cupholders though, with only the one squeezed in on the centre console vs the E70's two.

Oh and get this - it has a proper handbrake.  Jealous......  :)

Engine wise it's the 177bhp 2.0d unit which combined with the much reduced weight of the car and 4wd makes it a sprightly little thing off the mark.  At higher speeds it feels a bit breathless where the 3.0d would still have some shove, and at times you can tell it needs some more mid range but it's otherwise just fine.
Definitely lacking in refinement with the loss of 2 cylinders, and clearly some sound proofing (and I'm sure the 184bhp unit is smoother) but compared to the bland Audi 140bhp unit it feels like it has some character and is much more willing to rev.
MPG wise it's not bad - I'd say mid 40's.  Sure if we'd have got an SDrive it would have been better but this was otherwise the right car and I think my wife likes the extra surefooted-ness of AWD as her previous E87 1 series was a bit twitchy in the wet she said. 

In terms of ride, even with 17" * marked Pirelli RFT's it's night and day better than the E70 which crashes and bangs over things the E84 doesn't even notice.  It doesn't feel like it has a need to go to non RFT's as these behave just fine.  Think the SE suspension is squishy enough (apparently based on the E91 3 series chassis) but the handling is still absolutely superb and the car feels very pointy and level.  Combine this with the relatively heavy steering (makes the E70 feel very light when I get back in it) it is great fun to smash down a B road.  Less so in town as the steering can almost feel too heavy and I can't palm the wheel round when parking etc like I can the E70.  I guess here the massive weight of the E70 is unavoidable so the suspension in the E84 doesn't need to be stiffer than a stiff thing to compensate.

Aside from this, it boils down to the fact that the E70 simply has more toys due to being simply a higher spec car and in my case an LCI. Flappies with 8 speed, leather bum warmers, Xenons, even rear vents (the E84 doesn't have vents pointing at rear passengers.....).  You're therefore almost into apples vs oranges territory trying to directly compare them but I've definitely got to say getting into the X1 does put a smile on my face whereas the X5 feels better for lazy wafting.

« on: October 16, 2018, 06:16:40 PM »
Well, like many four wheel drive cars it gets away more easily in snow than a 2 wheel drive.  I find on ice, snow tyres are better than all season or summer ones. But, once it starts to slide - sideways or forwards - there's a petty large momentum (mass x velocity) at work and 4 wheel drive won't help there.  It can be frightening skidding sideways or head first towards something! The moral as ever is slow down early, brake and corner gently and plan on a long stopping distance.  As we say in the north east, gan canny!!!

This /\ - when we had snow at the start of the year in sunny North Yorkshire it gave me the chance to test it on the Bridgestone Duellers to see how the car fared.  Setting off wasn't an issue as traction was at play but after that and once you have momentum it comes down to grip which is a different thing and the car was difficult to get to stay pointed in the right direction due to its weight.  And stopping was also the same - the car simply went where momentum intended.  So 4WD or not, it boils down to tyres really.

I think I've just been lucky until now then - even with my old bangers.  Winter has normally meant things like glow plug issues and long cranking times etc for me but not had a battery go south just being sat overnight.  Oh well, at least it was a simple enough thing to sort and hopefully kills a few other weird birds with the same stone.

I've had many many cars in my time (including a few 3 series) and this is the first car I've had where the battery has just packed in/ gotten weak resulting in this sort of thing.  Sure I've had a few cars where I've carelessly left the radio on, lights on etc and got back in to find a flat battery (thus needed a jump, much to my embarrassment) but this car seems to be one that simply spanks its battery through normal operation.  Not just leaving things on by accident etc without the engine running.  Just goes to show the load and how busy the car is when unlocking it, putting the key in the dash and starting her up.  If you use the whole "his and hers" keys thing, the drivers seat moves to the saved position before even opening the door so the car is clearly always doing something.  The price you pay for "modern" technology I guess.

Having seen the battery in the boot it's a big old thing and interesting how the coding is required too - not just a case of slapping a new one on and that's it.  I guess 6 years and 80K miles is enough to render one pretty much kaput?

Thanks for all the replies guys.  It's the battery.....was flat as a f*rt.  You could hear the solenoid engage but no cranking, and when you tried the fans dipped - something I didn't notice before.  It started fine last night but this morning was no chance.  My concern was it was the starter solenoid or something, and I've hard starters in the past spin but not pop out (old Ford Fiesta) which needed hitting with a hammer to "unstick them".  This wasn't doing that, you could tell it was engaging the flywheel but not doing anything after that.

Got some jump leads on it and it fired into life straight away.  It didn't even have enough juice to take it out of park and into neutral when I tried.  And no sparks when connecting the earth jump lead - hardly any juice at all.

Also explains the weird recent phenomena where when getting in the car the sat nav split screen would always reset to "current position", the climate would change to a lower temp and turn off auto, and steering wheel would forget to come out into position etc etc.  All just a bit freaky and I've done some long journeys recently too - must be the lower temperatures which have finished it off.

So it's booked in at the local dealer for a new battery and coding etc next week - shorter runs are now out, DRL's and welcome lights are disabled and if need be I can jump the car on a morning from the wifes X1 which is parked next to it.

Auto.  The car was in park not neutral when I tried and is on the original battery AFAIK.  It's possible the battery is on its last legs (2012 car with over 80k on the clock) but I'm not at home to check the resting voltage right now unfortunately.  :(

I also tried both keys to see if it was a key battery / immobilizer thing and neither worked. 

It's definitely been much cooler recently though so it does stand to reason the battery doesn't have the guts to do it any more.

General X5 Forum (E70) / 3.0d won't start or even crank
« on: October 16, 2018, 09:28:18 AM »
Morning chaps,

Got into the car this morning and found it wouldn't start - not even crank.  You hear the pumps priming etc but nothing from the starter at all when you press the start button.

Where do I start?  Are the starters known to just fail on these things?  I've had starters before where they stick so they spin but won't spring out to engage the flywheel but this isn't even spinning, it's just silent after the pump priming etc once the button is pressed.

And if it is the starter, and needs replacement, are we talking a big job?  From the YouTube videos it looks plug and play (no coding) and an intake manifold off job to get to.  Replacement starters don't seem too pricey if not going to the dealer for one....

Thanks,

Chris.

General X5 Forum (E70) / Re: 7 seater tyre pressures vs 5 seater
« on: October 11, 2018, 09:41:35 PM »
I think the B pillar plate can be a little hard to interpret - not sure if it's just me?  And it doesn't seem to differentiate for the 7 seater vs the 5?

28 psi front and 32 rear seemed low to me too.....

General X5 Forum (E70) / 7 seater tyre pressures vs 5 seater
« on: October 10, 2018, 11:12:43 AM »
Hi all,

Looking around to make sure I'm running the correct pressures for the 7 seat setup.

I found this post http://xdrivers.co.uk/forum/index.php/topic,11448.msg118469.html#msg118469 which matches my 19" wheels but I believe his car was a 5 seater - does the 7 seater require different pressures with the extra weight?  Otherwise is a 28 psi front / 32 psi rear sufficient?

I'm talking unladen here - not 7 people in the car and a boot full of ironmongery.  :)

Cheers,

Chris.

On the basis of logic and the fact non RFT winters are offered by BMW for square setups it would make sense that non * marked tyres are ok for those with non staggered wheels.  My wife has just put a deposit down on an E84 X1 SE BMW AUC (so no staggered setup) and that has non RFT Pirelli cinturato p7's all round by the looks of things.  Jealous.....

Theoretically a 255/50/19 front and 285/45/19 rear would have the same rolling radius but it would appear that either due to less stringent manufacturing / QA processes, or the fact that non RFT tyres deliberately have more give in the sidewalls (resulting in unpredictable results once the weight of the car is on them) means the rolling radius might be just enough out to cause the 4x4 to moan a bit.  The more sensitive the car is to detecting slip (something BMW boast about with XDrive) the lower the tolerance for this being out of whack.

As I say, I measured my non RFT Hankooks prior to fitting and they were as far as I could tell the same RR, but my thinking is that changes once they're on the car due to weight and pressure variations.  Bit tricky to get string round them to measure the circumference once they're on the tarmac and see how much it's changed.  And my symptoms were far from pronounced like some of the horror stories I've read on here but sufficient enough for me to notice, and incidentally fixed by putting new Dueller HP's back on.    :(

My symptoms were subtle but definitely there and it's possible that a combination of the extra 7 seat weight and bigger profile tyres on smaller rims doing more of the "work" made the car not quite like it much?  I mean like 19" vs 20" or above - you could definitely see the sidewall bulge on the non RFT's even with pressures carefully set so they undoubtedly had more give which you'd expect.  I'm clutching at straws I know....

We're not talking 4x4 style crabbing when turning but the funny shudder now and then when turning/ parking, and the definite shunt when coming down the gears at lower speeds made me concerned. 

The ride quality was certainly improved with non RFT's and I do miss that, and it was also less fidgety at m'way speeds.  Shame.  :noexpression:


15
So, not so long ago, seeking better ride quality (and as my existing Bridgestones were on their last legs) I made the judgment call to purchase some non * marked, non RFT tyres.

Having the 7 seater meant that I needed the ones that could handle the extra weight - 19" 107 at the front and 111 at the rear (staggered setup).  This meant that the only tyres I could find that were of the right size, load and speed rating were Hankook Ventus Evo 2's from Tyre Leader (£500 delivered for all 4).

Upon arrival I measured the tyres (front vs rear) and even put them side by side with a spirit level and they were bang on the same, so I felt pretty confident.

Tyres were fitted and all seemed great.  The difference in ride quality was excellent, soaking up bumps that would've been a pipe dream before.  This was for the first couple of weeks, but then weird things started.

To begin with I noticed it as what can only be described as a "shunt" when braking and coming to a stop, or at least low speed.  It felt like a very aggressive downshift by the transmission and so I started looking into this as a possibility, resetting transmission adaptation values etc but to no avail.  The more I drove the car the more it felt like something "releasing" or "letting go" as the vehicles speed reduced.

Additionally (and this was what gave the game away) I noticed at lower speeds and when turning or doing things like parking maneuvers there would be the occasional mild shudder felt through the car.  Not all the time, just now and again.  This was on top of how the car felt like it was misfiring or coughing when at low parking speeds on and off gentle throttle, even when going straight - like the aforementioned shunt but repeatedly.

It definitely wasn't right.

The coincidence with the fitting of the tyres and the nature of the faults started to add up - it had to be the tyres.  Plus a call to the independent BMW specialist I use added further weight to it saying the symptoms matched what they'd seen on similar X3's - the transfer case wasn't happy. 

They explained that the loss of the RFT meant that the sidewalls were (intentionally) giving more than before and as such would confuse the traction control, which in turn affects the 4x4 system as it thinks the car is losing traction. RFT's maintain this regardless of weight and largely pressure so RR is maintained front and back, despite tyre width & weight differences and pressures, at the cost of ride quality.

So this morning I got my car in for a full set of 4x * marked Bridgestones sharpish in the hope I'd not done any lasting damage.  As I say the symptoms were subtle but noticeable and the sooner the tyres were changed the better.

Upon driving the car away I could tell straight away things were ok again.  Gone was the weird shunt when dropping down the gears or maneuvering at lower speeds, and gone was the weird random (and slight) shudder when turning. Back however was the harsher ride, although not as bad as I remember so maybe the newer Bridgestones are improved over the old ones?

So, I guess my story is testament to the theory that * marked tyres do indeed make a difference, at least in my case, guaranteeing rolling radius not through manufacturing techniques but also through their rigidity in the case of RFT's.  It might only be a thing affecting staggered setups, and possibly more of a risk on smaller wheeled cars (less rim & more tyre making up the overall rolling radius) but my experience was clear. 

I now have a set of 4x three week old Hankooks in the boot of the car which will be going on eBay shortly to recoup some of the cost........
