I posted previously when I was having a few issues with height sensors - cut a long story short I now have the new sensors fitted and attempted to re calibrate the suspension.
After a few attempts we managed to get the car sitting level at normal height and measured the height using the chart found on here, now the car will go to off road height, but when I choose access height the light blinks a few times as if it is going to but it does not drop and stays in normal height mode.
There are no error codes showing and everything seems to be working just it wont drop to access height.

any ideas?

You do know you have to have all the doors shut for the suspension to move..??

Try a battery disconnection procedure, see how to in the WIKI..

If not an EAS reset may work but you will need an IID tool or similar with the capabilities to do one...

Someone could have reprogrammed it to be the same as normal height, it can be done...!!!

If not, sounds like the EAS ECU is toast, or one of the others is in conflict with it...!! Pete

Cheers - aware of the doors will investigate the battery thing and see where we go from there - I know some people (including a mate of mine) said its fine the way it is but I am one of those people that would rather everything functions as it should we have a computer here and as mentioned there are no error codes showing on it so I am assuming maybe we just did not carry out the re-calibration procedure properly (I'm not sure what that is if there even is one!) I assumed (maybe wrongly) that once we set the car at normal height the others would just "follow" or do we need to set the height for each setting?

I think it depends what you used to calibrate the suspension?

I had mine done on a Snap On Solus, just measured it all in normal height and the rest calculated itself! 

You set standard height to calibrate, the other settings are adjustable and you set how much lower than standard access and motorway modes are and how much higher off road is.... They can be set to 0 so nothing happens..

Just because there are no faults does not mean the ECU is OK, they monitor and report errors on peripherals, they don't always self test themselves...

You really need a good session with a decent diagnostic tool to read and understand the live values, they usually point you in the right direction... You need someone who understands the systems rather than someone who just says there are no codes so everything is OK...!!!

For others reading this in future, you can only set all four heights independently on the 2002-2005 BMW based models... Pete

Cheers again we have two computers, a Solus and the other one (can't remember the model) both work ok but there is more on the other one than the Solus. I'll take another look when I get a chance this week or now its back drive able again a quick blast to a local indy is in order (although that's a 100 mile round trip hence why I try to get stuff done local if possible.

Buy an IID tool, it soon pays for itself and then you can do it all yourself, plus get home most times when things go bong away from home....

Look at it as an investment, it's worth a lot second hand.... Pete

Been busy so never got back to this, just to report back that a quick blast up the motorway to test that setting and everything is back to normal - Suspension is now working on all heights as before.
