Self Leveling Suspension InActive - Error code: Compressor Relay

[dark_stranger]

Guys, I constantly have the above message on the dash, although the height looks fine, plus all fuses are fine. I therefore plugged in a scanner 1.4 with PA Soft and there are various error codes, but the obvious code is "Compressor Relay". What, where and how easy would this be to fix? Obviously, I guess this is the cause.

I have found a document on the web that shows where the relay is located, but lots more useful information.

Now a trip to http://www.realoem.com/bmw/ and find the part number. Hopefully, this will fix the issue.

Found the part http://www.realoem.com/bmw/showparts.do?model=FA12&mospid=47740&btnr=61_4058&hg=61&fg=36

and only £4.99 on ebay, lets hope is really is only a £5 fix.

Replaced the relay, but still getting the error.  Attached the scanner and get the errors...



EHC

08/00 - Controling time, upwards

03/05 - Relay compressor



Any ideas?

Yep, it's a worn compressor. It's taking to long to reach the desired hight so it's assuming the pump isn't running so throws up the relay fault. A repair ring from bag piping andy off eBay should sort it out.

I used realoem to identify the part number and ordered off ebay. Relay turned up and didnt fit as completely different.  I would check the relay you have first and search by part number on the relay. Mine was a bosch.

Is it compressor ring repair kit I need? If so, there is a guy on ebay about 3 miles away that sells them.

[/quote]yep that's the one. As long as the pump motor is ok and the bore is not scored, the ring should fix it.

[X5-D-Sport]

Does the bore need any lubrication, or is it supposed to run dry ?

Cool, need to check its the correct pump make, but have messaged the seller asking if I can collect tomorrow.

Check ebay item 321370792426 and in the description section there is a video clip and documents as a guide.

Yup, bought one of these kits an hr ago, there is no mention of lubricating the piston bore, so presume it is assembled dry.

Now I need to find a relay, but can only find pumps & repair kits on Flea Bay

Search for Bosch Relay 0332019456

This is the one that fits an E53 Facelift (04) - 3.0i

Excellent- thanks for the numbers,
Ordered a NEW relay from Flea-Bay & the pump rebuild kit a few hours ago too....
Next weekend I will do this little job.
My X5 has done 140,000 miles, so this will be one job done to hopefully be one less thing to go wrong inconveniently...

I just started a new contract job as a Senior Engineer in the Midlands for a company that makes Air-Suspension Units... and by good fortune they make the E53 units for spare parts suppliers... and maybe we can save a small fortune if any of our members units fail here by passing on company details for parts at source.

I'm going to replace mine as a matter of course as soon as I can get my hands on a pair soon....
