BMW 750LI Suspension Air Compressor Replacement

This is a 2010 BMW 750LI that is equipped with rear air suspension. The rear started sagging and the air compressor was the culprit. So changing a suspension air compressor on one of these is not all that hard but just takes a little bit of time and a lot money for the compressor itself. Job calls for like 2 to 3 hours of labor but can be finished quicker.

What part of South Carolina are you located? The same side (rear passenger) as your video is sagging in my 2013 BMW 740 Li. I am in west Columbia.

[@operationoverhaul]

I am in clover, sc. This one needed struts about a month later. So, I would check them as well.

[@JustinBlaze88]

I’m in Maryland. I wish you were close man I’m having this same issue with my BMW 2016 750i XDrive

[@operationoverhaul]

Check your struts before doing the compressor because they will do the same thing as this one was doing as well.

[@fmspec]

Good video, will it solve chassis problem that makes front suspension goes down flat, when I press the level bottom the suspension goes up but it later deflates. It’s a 2017 bmw 7 series

[@operationoverhaul]

If it raises it up then deflates I would suspect either a leaking air strut, air line, fitting, or manifold at that point.

[@mickaelwilliams8966]

Hey my left side is sagging what u thank

[@operationoverhaul]

I would start by checking your strut to be sure that it is not leaking or check the air line going into the strut.

[@lou007]

BOTH sides where sagging? may you show a valve block disassembly? thanks

[@operationoverhaul]

Yeah, both sides were sagging and this only had the air suspension on the rear. Also, the valve block was replaced about 9 months prior to this. I could probably find a diagram of one for you.

[@lou007]

@@operationoverhaul what was the issue when you replaced the valve block? one side went saggy OR what? appreciated

[@operationoverhaul]

@loai yamani it would lift and work as it should but the suspension would slowly leak down especially while sitting because the compressor wasn't running when it sits.

[@lou007]

@@operationoverhaul much relieved as it's exactly my issue...do u recommend rebuilding v.b or just replcae thanks

[@operationoverhaul]

@@lou007 I normally replace as you can get them at a fair price actually. It is not hard to replace either.

[@cliftonjackson441]

im seriously not trying to sound stupid, but is bmw's air suspension just the rear? and is replacing the compressor and modules etc, everyrhing but the springs that easy to access? im asking becuase i want a 750 or a 2014 or 15 s550

[@operationoverhaul]

It really depends on what model and year you that determines if it has front air or not. Everything is pretty easy to access as far as the air suspension goes.

[@cliftonjackson441]

@@operationoverhaul well looks like its a bangle or ruskie 7 series or an e550/cls550 then. thanks for the quick reply

[@operationoverhaul]

@cliftonjackson441 your welcome and if you have any other questions as far as what to look at when you go to get one or even want to send me some pictures while looking at one jlfeel free to message me on Instagram.

[@Xatger]

Is there any danger in the bags decompressing air when you release the blue and red air lines. Thank you for your time and video it was very helpful.

[@operationoverhaul]

I have never had it happen to me but there is always a chance something could happen. So, I always have the jacked up with a jack stand in case something like that was to happen.

[@KristijanPetrovic-q7j]

Did u had to re program the new compressor

[@operationoverhaul]

No you do not have to re-program the compressor. They should he plug and play

[@jbrice8055]

I replaced both shock and value block and now one side will go down over night do you think it's the compressor?

[@operationoverhaul]

I would check all air line fittings and lines to ensure they are not leaking then I would look at the compressor

[@jbrice8055]

Not leaking anywhere so I will check the compressor. Thanks are you located in south carolina?

[@operationoverhaul]

Yes, I'm in south carolina.

@Operation: Overhaul me too do you have a shop? I'm in rock hill sc

[@operationoverhaul]

@J Brice I'm in rock hill too. Where about do you live in rock hill and I could come look at it for you one day? Actually send me an email with your phone number and I'll text you

[@hexasmartitagency5620]

My BMW 730 LD is sagging only one rear suspension. Also when the car climbs a ramp of my garage, it saggs again and take a lot time to stand up again. I don't know where is the fault. BMW official service stations are not trustworthy here, they intentionally inject some kind of code which shows error within 1 month.

[@operationoverhaul]

how long does it take to lift up again and when it lifts up and the compressor turns off, can you hear any air leaking out?

[@hexasmartitagency5620]

@@operationoverhaul so basically there are 2 ramps to park in my garage. I have to turn off and start engine again after the first ramp to compress the air in suspension again, car doesn’t identify the sagging it self. I need to restart the engine to make it compressed quickly. Also there is no sound of leak or compressor. It quickly lifts up after restart.

[@hexasmartitagency5620]

@@operationoverhaul only 1 suspension is segging while climbing the ramp.

[@operationoverhaul]

@Hexa Smart IT Agency almost sounds like a bad strut or valve block one. One of them may be leaking slowly

[@bin3129]

I hear leak what should i change !? The air block? Or what because i dnt trust the mechanics in my area... they all said the compressor needs changing but i can hear it work and the car lifts but suddenly falls back

[@dajuanellis3296]

Where can I buy the blue and red hoses

[@operationoverhaul]

Try looking on fcpeuro.com and if they do not have it then you may have to go to bmw to get it

[@lotus8262]

Great video, did you change the relay as well? How to do it?

[@operationoverhaul]

No, I checked the relay before I put pump on. It tested good but if you would like instructions on replacing the relay I can get those foe you

[@lotus8262]

@@operationoverhaul yup, I think that'll be helpful for others as well, although I'm gonna let the mechanic do it as the bottom of my BMW 5GT on driver side is covered with a black plastic n I don't know how to remove it, making it impossible to reach the last bolt. Cheers mate.

[@Steven-b5y]

Great video!! I e seen that same car cause I’m from Columbia,sc. lol can you shoot me your number please? I’m having pretty much the same issue.

[@operationoverhaul]

hit me up on Instagram and Ill get it for you.

[@bin3129]

I got the same car but the compressor lifts the car and suddenly slams it down.. and keeps shuddering while i drive... im worried to pay for a new compressor and the issue isnt it.. so anyone know what it could be..? And plus if i put my hand over the blue red lines i feel like its leaking

[@operationoverhaul]

It sounds like your compressor is working but your airlines are leaking. Use some soapy water in a spray bottle and spray the lines to see where the leaks are.

[@bin3129]

@@operationoverhaul yea seems like a leak ..i did that but what do i do of the lines meed change?
