E70 ride height warning

[Greydog]

OK
Just looking at realoem
This is the parts list that goes with the drawing attached yesterday the sensors are labelled Item 1 to the left and item 7 to the right. Take note of Item 7 Vehicles with self levelling suspension 2 off but all levelling sensor part Numbers are the same
I hope it makes more sense now

Id get a look under there first see if its the wiring is bodged or the actual sensor is faulty or the little link arms have come off.

[sapphireblack]

The wiring on both is apparently bodged from a recent health check report.

And the plot thickens. Without doubting any input here i wondered what genuine parts might cost. That stirred the situation at the dealership somewhat, as my car was apparently showing as a US spec. OK, so we know they are built there, but the steering wheel is on the right side in my car, which they have had in the workshop only recently.

Anyway, after a hiatus, i just got this via email. It shows different part numbers per side, so i am even more confused.

We have finally found them! I had to pull in the parts manager from Tunbridge Wells too and he was stumped as well.

The part number you gave me is correct but I wanted to confirm that they are correct for your car.

37146853753 - £84.89 + vat
37146853754 - £78.37 + vat

Both are available to order 2 day lead time.]

I wish i was more hands on. Looking back on the heath check report, it mentions bodged wiring as i mentioned above, it doesnt condemn the sensors.

Maybe i need a good wiring man more than new sensors!

[Leslie]

The front left sensor is probably for xenons mine has adaptive xenons and has a left front sensor . Depending on whats actually wrong with the wiring a used plug with some wire to reattach is maybe the best way forward and get it soldered in.

looking at realoem 754 part is a front and 753 is a pair of rears , the left of which has a bracket possibly the right doesn't need a bracket , my car isnt at home to check as its broke at the minute You can see number 2 is a front bracket and the operating arm is at right angles where the rear is parallel , that will likely be the only difference between a front and rear but they wont be interchangeable .See below

I appreciate the continued guidance. I can't lift the rear end of the car on ramps as I don't possess any, and knees are no longer conducive to handling wheels on/off without some difficulty, if i can avoid it.

I know an auto electricians near enough to visit. They have a full lift and can get underneath it. I think I'll start there before buying any parts on spec. It could just need a wiring tidy up?

If ...753 is a paired set up even the dealership has got it wrong.

[Leslie]

They probably assumed yours had xenons as most cars had the 754 shows for adaptive drive and 753 for adaptive drive or self levelling suspension so its a bit confusing really but part 2 the bracket is shown for front and linked to 754 so I can only assume its the front sensor .
An auto electrician sounds like just the man for the job .

[sapphireblack]

Well the car does have air suspension but not very much else. Halogen headlights and manual folding door mirrors.

It is poverty spec for sure and a totally different animal to my E71.

From what is easily determined, the car was built March 2009 but it was only first registered September 1st 2009. Clearly, it's not a customer vehicle order.

[Leslie]

I have auto folding mirrors and given the width of it them are needed for parking , its definately poverty spec lol maybe a company purchase that had to be under a certain cost.

[X5Sport]

It might have been ordered just as the financial crash of 2008 happened, got cancelled and reduced to minimum spec. Dealer probably still had to take it.

All plausible i don't doubt.

So the auto electricians i know actually declined to get involved its a BMW But they did refer me to an ex techie who i have spoken to and seems to know the issue.

I'm waiting on a call back to tell me when to bring it to him.

I don't regret buying this car just yet, but it ceased being a budget vehicle a while ago. It is still better suited to a life in Greece than the 'mint' E71 so ill keep cracking on for now.
