Ok this motor is driving me to distraction , but O love it but really what is wrong now !

For a whole the front right air bag lines have been troublesome, especially the right. I have replaced the lines a while ago , then the air tank , as it was rotten. Then the filter and seal kit for AMK compressor.
The car has worked away on the suspension but for the fault showing air compressor slow to rise . I have noticed that as the orange light appears the font right indicator on the suspension screen is behind and so O have ordered a height sensor, given that the following code has and continuously appeared.Also showing others with u code as they do.


The car is presently sitting on its hunkers and refuses to lift ,so I have ordered a new height sensor , but is the compressor finally had it ?

I think I will try and edit photos , they all seem a bit spread out or repeated . So please bear with me.

Slow to raise is a fair bet the compressor is weak. You say seal kit ?? What exactly did you replace?

4x4 Airseals supply kits for solenoids front and middle and rear, rears have never been touched as never been a problem . However the compressor seals and the filter drier have been changed plus the the seals on the voss pipe connections . The front solenoid complete has been changed for lessor priced one , but meanwhile I have the RR one refurbished with a full seal kit change .The main tank is new also. So pretty extensive overhaul.

To top it all the Active Roll pipes (ACE) have also been replaced to the front .

New compressor time

Or, the pipes to the valve blocks have been refitted incorrectly.
Don't be offended, I've seen it more times than I'd care to remember

Always open to help Mike, thanks suspension has been ok for a few months and more since all that work was done , does look like compressor. I'll check power at the w/e if I can get it up off the ground !

Using GAP, and live values , as I can't get to the plug at the moment. I went straight to live values on start up as the module takes a little more time to begin its checks and the compressor V showed 13 very briefly and the dash cut to the symbol with suspension fault , with voltage at 0v.
I shut all doors and re enabled the EAS, pressing the switch up or down according to instructions and I could hear the pump for a short period with an unusual buzz I guess and it cut out and locking the suspension again. I can't get back to live values quickly enough to observe the voltages, so I am still guessing that the pump is faulty.

Ign on
Clear faults
Navigate to live data
Select required info
Start car
Watch data

ON THE CASE !

On instruction , and what confirms my thinking advised by Micky disco , I screen shot the suspension live values when selected and then the ign switch on and start , I get this
:


After 15secs approx when the suspension wakes up ,I get this :


so asumption is I guess?

So trying to be sensible and not paying for genuine at £900
I can get an AMK which is installed in my car, pt no. LRO 78659 , yet to check for sure , but this can be bought for £160 , (ebay Amk copy) what has everyone else done , given I'm not waiting 14yrs for this to happen again.Has anyone replaced with one of these with cheaper copies.

Received wisdom is that the very cheap eBay versions last anywhere from days to weeks.. Advanced Factors have AMK for £477 and Hitachi for £500ish, though. 2014 BMW 530d Touring, 2006 BMW 650i, 2018 Mini Cooper S

Awaiting 2nd hand compressor that says it new condition with 6mths warranty , not a bad price at £219.

"Buy cheap, buy twice."  2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Right? You only have to look at the first two entries in the cars in my signature...  2014 BMW 530d Touring, 2006 BMW 650i, 2018 Mini Cooper S

You need to be more specific , sorry.
