Um, I screwed up a setting
 

I must have done something wrong that I can't find...

I was trying to set ride height and used the factory option and the 20" wheel setting, but the NT-510 said adjustment not needed. Afterward the X was sitting so low that it almost scrapes the road reflector pucks while bouncing like a lead-sled and my height adjustment rocker switch is blacked out. Running through the tests all valves, pumps and switches show everything as functional.

Ideas? Thoughts?

I must un-f this as I'm not sure if I'll survive driving a very short, pregnant, pissed off woman to the doctors appointment again..

I'm hoping this isn't my last statement to the world as I wanted it to be...

Why, yes baby those jeans make your ass look fat..:stickpoke:[emoji38]

But seriously she's pissed so any help is, so very very very much appreciated..

Have you tried with INPA? It sounds like your leveling adjustment is just off..

I used INPA but it has no default setting. I ended up paying my local Indi to set it up for me on his computer (which has a factory default). This was after I spent hours trying to level it using the INPA quoted levels.

It sounds like you are so low you are running in the bump stops? That being the case you may get tire rubbing issues as well as wear issues.

Update.

I still am not sure how I got it into transport mode AND wiped out the ride height. I still can't get it to delete transport mode, so I'm disconnecting the battery and putting the + and - together for a bit and I'll add the battery back in and start coding there.

Pregnant wifes' sense of humor is now less than ride height of the X...

Update again...

So here's part of the reason why I wasn't getting this un-F'd.

Didn't know that my OBD2 was dying.

Now in search mode.https://uploads.tapatalk-cdn.com/201...7068fae83d.jpg

Search completed.

I got parts off a smeared X and now the OBD2 is back to life.

Rear suspension is now down do to this resistor (so far) and of the 3 I've found from wrecks all were toasted. I am hopeful that the stealer has one in stock.

Nickles and dimes is about all I've left after what seems like two weeks of shop time and professional scanning time/help.

Wife is now more P.O.'d than ever...

If I disappear, I swear that I did NOT fall down the stairs while holding a chainsaw!!

Wish me luck on my X5 Zamboni repairs....https://uploads.tapatalk-cdn.com/201...38c5cba95e.jpg

Have you call your local dealer?

I'll be going in on Saturday as Friday in the Middle East is their holy day.

Well I am still not sure how the resistor for transfer case can cause a cascade type failure that locked down my ride height...

I also forgot that today is Saudi national day, so this is all that's going on here today. https://uploads.tapatalk-cdn.com/201...93f224eb60.jpghttps://uploads.tapatalk-cdn.com/201...b0fccec39d.jpg

The part number in your photo is for a classification resistor for an E70, not an E53. E53 part would be 27107557345.

Also, it is my understanding is that the classification resistor is specific to each vehicle and is part of the calibration to allow for production tolerances in the xDrive clutch plates. I don't know if you can simply replace it (without some form of re-calibration). :dunno:

And what the hey has it go to do with your rear suspension issue? :dunno:

Also, what did you mean when you said your OBD2 is dying? The photo of the connector didn't have any clues... or was it just that the connector had fallen apart...? :confused:

*edit* - found this statement regarding the classification resistor...

Coding Resistor

Manufacturing tolerances lead to varying curves of the multi-disc clutch. Because of this, the actual locking torque is be measured on a test bench during manufacturing. Because of varying manufacturing tolerances in the transfercase when they are manufactured, a resistor equaling these locking torque characteristics is mounted to the transfercase. Everytime the engine is started, the transfer case control unit measures the resistance and the correct program map is selected.
