I used a combination of the software included with my cable and a pre-made EasyDIS v44 UNIX VM I stumbled upon torrent. I'm loading it inside my Windows XP VM which has INPA 5.01 and EDIBAS 6.4.3 installed. I understand how it works now (I think) and finally have DIS talking to the Diagnostic Head. My EDIBAS/INPA install appears to be working now as well at the same time so it SHOULD work.

I may have the wrong cable though, which sucks because I only seen to be able to connect to the engine and trans modules even after soldering/bridging pins 7+8 on my cable.

I think this is the root of my problems. Won't the compressor burn up if either of these conditions exist though? Or does the EHC module sense a fault the compressor and cut voltage to it if it's seized? What is the likelihood a compressor needs to be replaced entirely?

I really need to bench test my compressor and see if it fires up.

Some!! Not all faults will stop the compressor from running. INPA will normally bypass this in “hand control” mode, allowing you to operate the suspension via INPA.

Hello,

I have a X5 4.4 2003. 2 axle suspension. Trying to calibrate the EHC but what I don't understand is why is the deviation for front left sensor shows "-2200mm" and others show around "130mm". How do it get the front left sensor deviation corrected. Any advise will be appreciated. I Have been trying to calibrate it since 3 days now with no success.

What happens is when I drive the car after the calibration, the car drops down and the warning appears with fault code 64 distortion plausibility.

If using inpa? on >Calibration/Set Height you have to ignore the deviation figures.

What you have to do is get the truck 100% level.
Then measure from the ground to the fender center via the wheel center.
The difference between that measurement and the stated default is what you are need to correct, regardless of any "Deviation" numbers.

TIP: get a bit of paper & a pen and write down all four corner measurements BEFORE you start to enter them into the system. Ideally you only want to do this once.

With inpa: Make sure that you have cleared any errors prior to entering your numbers.

Engine on
Drivers door ONLY open.
Enter measurements
Close drivers door
Watch car re-calibrate.
Give it a few minutes to finish & settle.
Remove inpa etc.
Turn engine off, remove keys, lock car, wait 15 minutes.
Go back and check that the settings are still good by using the Manual dash switch, to raise and lower the car.

Do you enter the difference between measured values and default values or do you just enter exactly what you measured?

Apologies. It’s the difference between the default and your measured height.

Here we go again... same as it ever was...
 

Arrrrrgh!
Hi folks.... I've turned up back on this thread like a bad penny!

Quick question to the experts re: ride height again...... again..... again.....

Having restored my compressor with the 'ring' & new cyl head couple years back, my air suspension has worked perfectly ever since - SLS inactive once when I went to South France (v hot) & my YAW sensor under centre console fried... anyway.... back to the ol' subject that we all love!!!!

I have had the car (ride height) levelled (re-calibrated) twice since then - nothing major but whilst replacing the odd bit or suspension arm had it done whilst there.

I have always used my indie BMW guy to do this - he charges peanuts and once did not charge me at all once..... I watched him do it - loaded up the car (full tank & lots KG's) & plugged his machine in... goes through a sequence (& mine as 4.8 was set at the sport level) & at the end (regardless of resistance readings from sensors) sets the default zero level.

Lately my ABS has been cutting in (fighting back when not wanted)... turns out that if a single front height is wrong by over 30mm it in turn causes the steering wheel to be slightly off kilter when driving straight - this acts with the steering angle sensor & YAW & confuses the ABS system.... but no faults or codes show......... when pumped level problem desists.

OK - here it is - sorry for pre-amble.
I'm RHD
My NSF height is 40mm below where it should be - other 3 are fine - no leaks etc - all functioning - but always returns to this!

BMW guy says that car thinks it is level - so keeps returning there.

Q... can I sort this myself?? I can raise & lower corners on my pal's machine but cannot then set zero. If so what machine & S/W do I need - can I buy it cheap?? HELP..... if not how would I sort this (pump up NSF by 40mm) & set zero level? Is there another system that maybe a local garage has...... pls advise on spec.

Another couple of guys had this - one had a bent track arm from hitting a pothole - the other had a knackered (distorted) little plastic arm from sensor to little mini ball joint. No faults but car not level!

Another guy levelled his by rotating the sensor bracket very very slightly in order to demand more/less pump in that specific bag...... is this legit - or asking for trouble...??

Pls help - as here we go again!!!

Is still anybody here ???

looks like you already have a good idea on what to do.
You’ll just have to get under it and try those things. Nothing is easy when it comes the this suspension.
I liked using DIS to adjust/calibrate the height. It has a complete diagnostic routine for the suspension in addition to calibration.
If one corner is always off, you can just adjust your measurements during calibration to compensate.
