General X5 Forum (E70) / Re: N/S front tyre wearing on outside edge

Vast improvement, it was well out

Yeah. Had poly bushes fitted to the thrust Arms whilst it was in as the originals were shot - stomp on the brakes at low speed and you could see the suspension bump forwards and back again. Now feels like a new car to drive, the difference was noticeable immediately setting off home afterwards. The chaps at the place I took it did an excellent job.

EDIT - Now booked in with an independent Hunter place near me on Thursday this week.  Very knowledgeable on the phone, cheaper and more "whilst you wait".  Dealer was typical response when I tried to quiz them about the nature of the alterations. 

I'll take in the photo you posted above to show them :)

Well it's currently booked in with BMW Doncaster to have the 4WA done next week...... Not sure where else does a Hunter 4WA around me.  Will need to look.

In terms of pressure if the fronts were slightly deflated I'd expect wear on the inner and outer edges but this is outer edge only so it has to be toe. O/S is fine as it happens and inner wear on the rears is minimal.

Just the standard 19" Bridgestone Dueller HP Sport * marked RFT 's........


The rears are £180 a pop as they're wider on the staggered setup :( ......

Cheers for the reply.  BMW want £149 for a 4WA so I'll get it booked in me thinks - considering the fronts alone are £170 each, I don't want to be replacing tyres as a result of premature wear really. And I'll ask them to sort out the rear camber whilst they're at it :)

Spotted the other day, quite heavy wear on the N/S front tyre outside edge, whereas across the rest of the tread is quite healthy - like I've been doing nothing but go round roundabouts really fast for hours on end... 
The O/S tyre in comparison is wearing evenly across and the rears are ok with just the usual feathering on the inside edges as expected based on the camber.

Can the front camber be altered to counter this or am I talking worn bushes etc?  I doubt it's track rod end adjustment due to the way it's wearing.

Realised I created this thread too re this.

This issue, and the 3rd row blowers not working is as a result of a failed IHKA high unit - aka the main thing in the dash with the knobs on and little display with the climate temp etc. 

Turns out the unit I had is superseded by a new one, possibly due to issues with the old one.

Part codes are (for anyone interested or who sees similar issues):

Old one: 9262781
New one: 9310449

The new ones are £850 plus VAT from BMW (vs circa £500 for the old one) but I got one off eBay for £110 including shipping.  Plugged it in and it worked straight away with no coding - I just need the coding now to get my 3rd row up and running as the replacement unit was from a car without the 3rd row seating option fitted.

I think its the same with warranty claims and servicing.  During your warranty period you don't invalidate it if you have your car serviced outside the dealer network and use OEM parts.....but in practice I'm betting most stick to the dealers as they don't know this, and also the risk that the dealers (regardless of the legalities around this) will make your life difficult in the event of a claim......

Now tyres are an interesting one in that pretty much anyone who hasn't heard of * marking etc would assume they can throw whatever rubber they want on the car and that's fine - I think considering the potential implications (and I don't think BMW are alone in this with other AWD systems being prone to wind up to varying degrees) it needs to be emphasized more that this is the case......but then would that prompt people asking why, meaning BMW have to open up about the whole thing, and so on?

Did we determine if people had warranty claims declined on the basis of using "the wrong" tyres?  I can't remember.

Just in case anyone is still trying to work this out...I've a 3.0SD MSport with 19" staggered set up. 235/45 fronts and 255/40 rears. I replaced all four with new Continentals.

The transfer case clunking that ensued was extraordinary. After a process of elimination (and after being advised by two BMW Indies that it wouldn't be the tyres - as they were the correct size, all the same tread pattern and reputable manufacturer etc)... I decided to change the tyres to a set of BMW star marked Pirelli P Zeroes. Which solved the problem.

Now here's the interesting thing...when the Continentals were taken off and a front and rear stood next to each other, there was a large difference in diameter (20mm). When the Pirellis front and rear stood side by side their diameters were identical - even though they were stamped with the same width/aspect ratio as the Continentals. So Pirelli 'massage' these specific tyres so they have the same circumference and bingo, the star marked tyres do their job.

See now this is the sort of post a thread like this needs.  Very specific in nature, brief and to the point. 
And with the extra info around the 20mm (which is a lot) difference in diameter it has actually made me re-think my future tyre replacement......  :noexpression:

It also answers my questions about the staggered setup and the manufacturer doing "extra things" to the tyres to make the RR the same front to rear, and also compared to other reputable brands (not your Wan Li ditch finders).  Curious about the manufacturing process still although that's kind of irrelevant other than to service my own curiosity.  Also curious as to why BMW are not more up front about this, or educate their dealers better to advise customers that this is the case with X-Drive cars. 

Ask most people off the street (myself included prior to owning the X5) and they won't have a clue what wind-up is on a 4x4, let alone how a staggered setup massively increases the risk of this happening.

I am due a pair of fronts by the looks of things quite soon as the outer shoulders are fairly worn.  The rears are not too bad but have a bit of feathering on the inner shoulders instead.  As such it would be nice if I could replace them as pairs rather than all 4 at the same time, simply to spread out the cost a little......With * marked tyres I'm now believing this makes this possible?.....

Update No.2:

Fitted the replacement part myself last night (pop out the front centre air vents with the glove box open, 2x screws to remove at the top of the main panel under there, then pull out the fascia to reveal the cabling behind the IHKA and CD player unit).  5 minutes later it was all cabled back up and hey presto we have fully functional front vents again including the iDrive integration where it shoes where the direction of the air is going etc - no coding required for this.

However the 3rd row is still dead but I was warned without coding this would be the case as the replacement unit likely isn't from a 7 seater and won't be aware of its existence in mine, so I've fixed one (big) issue quite easily and the other just needs coding to sort.  I know coding will sort this as a borrowed IHKA unit from an older 7 seater brought the 3rd row fans up straight away but didn't communicate with the iDrive properly as the main screen air direction stuff didn't behave itself.  Booked in for coding on the 10th of August.

UPDATE: After taking it in to have the 3rd row control unit replaced, it didn't fix anything.  They had another X5 in the yard that was being scrapped so they borrowed the main IHKA unit from it (the one from the dash with the buttons on) and plugged that in (no coding at this stage).  As a result the 3rd row climate fired into life and the direction of the air was once again controllable in the front.  Obviously minus coding meant that the display on the dash didn't work and etc but it was enough to prove the point.  A faulty main IHKA unit.

Looking at the parts catalog, the failed unit had been superseded by a new one with a different part code.  Old part code - £500 ish plus VAT.  New part code, £850 plus VAT.....sigh.

So I managed to find a used one on eBay for £110 so waiting for that to be delivered and then see how we go.

Love those wheels - very nice choice. :)

Gotcha.  It does definitely do it more after frequent short journeys - I was wondering if it was related to simply the increased rate of stop start process and there being a higher likelihood of it doing it as opposed to thinking it may be battery drain (which had never occurred to me).  If that makes any sense.  Have no issues starting etc but the car is now 6 years old (it's a Feb 2012 registration) and has 76k on the clock.  Battery due replacement?  Might ask my local dealer how much they'd charge for a new one to be fitted.

Every now and then my steering wheel will also "forget" to come back out and I'll have to press the adjustment button manually but that is much more of a rare occurrence.

Ah - in which case I already do that and use the memory buttons as stated, but now and then it still does it, sometimes quite frequently (several times a day if I'm doing lots of stop start).  :(
