General X5 Forum (E70) / Re: 3rd row blower / vents not coming on
« on: July 09, 2018, 04:09:35 PM »
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Looking at the parts catalog, the failed unit had been superseded by a new one with a different part code.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).  :(

Ooh, how do you do that?  Assume it's in the manual.

My seat settings are saved in the key and that works fine but I didn't know you could "force it" to save the iDrive settings in there too? Unless it does it by default and it's a bit flaky?

Has anyone had this or found a solution to it?  More of an annoyance than anything but, seemingly at random, if I choose anything other than "Position" on the split screen display (such as "Map Pointing North" which I tend to go for) it has a nasty tendency of reverting back to "Position".

Searched for it and found this but nothing definitive:

I had it in for a diagnostic.  The control unit for the 3rd row is dead - totally non responsive so there's a fault code logged with the main IHKA unit.  There's power to it and connectivity is good but the unit is dead, so that's on order for replacement and coding on the 9th of July. 

Fingers crossed that sorts it - was going to post up in here after the event.

In terms of getting answers, yeah this thread really hasn't cleared it up much unfortunately and the evidence either way is fairly anecdotal with some claiming that they've seen failures as a result of not using the * tyres, and some having failures even with the * tyres installed. 

IMO BMW themselves would have you use * marked tyres :

1. As leverage to get out of warranty claims should your car fail and you not use them.  Warranty claims cost them a fortune and any opportunity to reduce these overheads will be taken.  Would love to see this challenged in the small claims court as choice of tyres, providing they adhere to the size, speed and load ratings from the factory (which is what insurance companies also want, although they are only concerned with safety) should be the consumers choice.
Adding the * marked thing into the mix is likely not to wash, and in territories like the US I bet they can't get away with telling people "no, we're not going to fix your car sir as you aren't using Bridgestone Dueller HP's all round that were replaced at the same time to guarantee they all have the same wear levels etc".  They'd be on Judge Judy in a heartbeat.

2. To keep the tyre manufacturers happy as no doubt there are deals and / or golf course agreements between them that these tyres will be promoted.

One thing that I've wondered with all of this is the BMW approved used program, where they sell X drive cars with an extended warranty and with whatever tyres happen to be fitted to the car at the time, assuming they have sufficient tread depth.  My 2010 3 series (bought in 2013) was from a BMW dealer and had all random tyres on it (all decent brands but not matching all round) but they said as they all had decent tread on them they wouldn't fit new ones when I queried it.  Admittedly I had lost some bartering power as I was trading in my Civic Type S at the time but still, if an XdDrive equipped car leaves their premises clad with whatever rubber happens to be on there, they'd have a hard time denying a warranty claim should there be a problem.....

Personally, my choice when my 19" Dueller HP's wear out will be to put non RFT's on and that's a decision I've made.  All 4 will be replaced at the same time, with Hankook Ventus tyres (the only ones that have the correct size, speed and load rating as mine is the 7 seater) and I'll relish the expected vast improvement in the ride quality as a result, in addition to the reduced unsprung weight and the benefits that brings.

Could have been doing a DPF regen?  When I had my glow plug control module replaced (which plays a key role in this process) it had like a white haze on acceleration for a bit immediately after (once it had warmed up) then it stopped and hasn't done it since as far as I can tell.  Just a thought.

what is the need for having staggered wider rear wheels?

Common on "sporty" cars.  Standard fit I believe on the MSports.....

Note, the choice of tyres is supposedly related to issues with the transfer case on the differential, not the DPF (which is an exhaust component rather than drivetrain).  All down to possible differences with rolling radius between front and back on staggered setups (where the rear wheels are wider than the fronts).

I like these but don't believe they were possible on the M Sport like mine.  Adds to the look of the car and I'm sure would have helped my Dad who has much reduced mobility to get in and out as it's a bit of a climb otherwise.  Oh, and for washing the roof :)

This was an interesting read....


About how ISTA cannot diagnose the 3rd row control unit .  Tempted to pull it apart and see if it's getting a 12v supply.  Could be the microswitch that's faulty, as simple as that.

Actually recommends a full power cycle on the car so I think a battery pull might be in order.

Hi all,

In the saga of diagnosing why my front dash vents won't come on at all (defrost / windscreen only) I've noticed that the 3rd row vents won't come on either.  Press the little button and the LED doesn't light up - nothing happens.  :( 

I'm on a blown fuse mission anyway (which helped me figure out why my power outlet in the boot doesn't work :) ) but struggling with these other issues.

Spotted I'm missing fuse 126 from the boot fuse box but having borrowed another 5A fuse to pop in there temporarily whilst I buy some more of the little fuses, it's made no difference.

Anyone else had this?

Hmm - but for all actuators to fail at once?  And for it to also refuse to do anything on the recirculation front either - that's stuck in position (sorry only just realised that)......

Googling this, it seems others have the same issue and it's battery related?  Like if the battery is ageing/ weak then the climate refuses to let you use anything other than defrost.



Will get the multi-meter across the terminals this weekend I think and have a look.  Not sure if the battery replacement on these things is straightforward if this is the issue? Coding etc.....

It has also been doing other strange things a lot more recently too, like the electric steering wheel adjustment forgetting to come back out when I get in, the split screen sat nav going back to "location" and not "map north facing" (which I keep choosing) much much more regularly.  My journeys to work have been much shorter recently since we moved house so it's not getting quite the usage it once did, but it does get long runs at weekends......
