Air suspension does not opperate

Hi, I am working on a BMW X5 98'model. The air bags does not work on this vehicle. I have tested the airbags for leaks, no leaks detected. I have also tested the sensors and could not measure any resistance at all. When testing the air suspension computer, there are no voltages going to the sensor cables, yet I do have an incoming current and an earth on the computer box. The air bags are fitted to the rear suspension only. Regards, Riaan

Air bag pump is running, new airbags . rear bags wont air up.

These Lincoln air suspensions are terrible. I have converted many over to coil springs at a fraction of the cost of replacing/repairing the bags. If the rear bags don't inflate, there is a broken air line to the bags or the bags are leaking

There are 2 types of airbag systems. The protective restraint system in the interior of the car; and the suspension bags under the car(These can be referred to as airbags).

When fooling around with either, disconnect the vehicle power.

The interior airbags are in the dash, and steering wheel hub. Sometimes early options added side "curtain" bags deploying from headliners or seatbelt housings. These should be left to experts because of the explosive charge and the danger of breaking the fasteners that hold the plastic covers in the interior.

For suspension airbags, they are mounted in place of coil springs. If you have a question, you might want to resubmit it with a symptom that an Expert can help you with.

There is high pressure air in the system and some models have a bleeder valve on the airbox to neutralize the system.

I believe manufacturers may have developed a scanner for the interior airbags, the better scanners can do the suspension.

How long does it take to fix the air bags in the air suspension in a lincoln town car

Every repair place you go to, will have different recommendations
for your situation

You have to decide if you want to spend money on a 19 year old

Personally I wouldn't, & I do all my own work & get parts at a discount

Think about your question
How would we on the internet without the car to test,be able
to tell you if it was the compressor,air bag shocks/struts or
compressor,plastic or metal air lines,electrical issues,etc

If your keeping any vehicle,with air suspension, I only have one
recommendation every time I get this question & it applies to
almost new vehicles as well


There are at least 6 big well known brand name companies that
make conventional replacement shocks etc

You remove the air bag deal & replace with a brand new,not
reconditioned,vehicle specific shock complete with the spring
necessary for your vehicle

The how to disable the air compressor,remove or tie up the
air lines & other issues is up to you, or may be in the instructions.

On a 4 year old ford or lincoln you can't afford to have a dealer
try & diagnose those systems,not from what I see on this web site
The dealers can't resolve their own products anymore

Airbag light

all the vehicles i've ever worked on, about the air bag light thing.
Vehicles have what is known as a clock spring under the steering wheel, you have to pull the steering wheel to get
to it. VW may call it something else. That clock spring allows the steering wheel to be able to move, and it feeds
info to the steering wheel air bag. it's nothing but a wire connection that moves without breaking. After a lot of
driving the spring gets a lot of action and will finally break so the info is then blocked and the air bag light goes on.
If you decide to tackle it, disconnect the battery first thing, you could set off the air bag if you don't. The clock
spring can be removed and tested with a volt ohm meter to see if it has a reading or not. no reading bad...reading of
any kind good. The spring isn't cheep, and the repair isn't easy. You also have to be sure you have everything correct
or the air bag can go off when you reconnect the battery.

Rear air bags lose air pump works when car stARTS

Hi Marco, take the vehicle for a diagnostic scan and that should be able to pin point the actual problem. I believe the vehicle may have picked up a slow puncture or maybe there is a problem with a valve? the reason for my diagnosis is that the air bag is able to pump during a journey and then deflates (I hope we're talking about he suspension; I haven't heard of a ford with air suspension, but that does not mean they don't make one.) If we're talking about the SRS air bag system then a scan is even more important) Regards John

Air bags suspension won't inflat. Checked all fuses & air suspension switch. What can the problem be?

Probably failed seal or air bag leaking air. Check again and try to see if this will do the trick. Sometimes pvc line could fail to deliver air to the bag too!

When airbag go down n back could it be the relay for airbag under the hood

When the air bag(s) won't hold air it's usually an indication of a bad air spring. It's a common problem for air ride suspensions such as yours. It's also advisable to replace the bags in pairs, especially if you have original equipment.

BMW 745i airbag light. Told to replacing airbag clockspring

Hello , check the airbag contact sensor behing the grill assembley . They are located to the left and right of the grill almost to the headlight assemblies. Check the wires to them for corrosion and damage. Check the fuse as well. There should be an air bag testing wire or fuse in the fuse panel. DO NOT UNPLUG THE AIR BAG SENSORS OR HIT THEM !!

Air suspension not leveling the vehicle as it should

no the air supply line must be leaking to the air bag, go back and complain, these bags last about 75-100,000 miles.
