TD5 Rear Air suspension problem

<< < (2/4) > >>

lyndon:
I take it its possible that once the compressor is off when parked pressure slowly builds up in the airbag owing to the weight of the vehicle on it until it reaches a point where the faulty seal just gives out. Sounds feasible.

Range Rover Blues:
Pressure in the airbag will always be there, but without the ignition there is no compressor to keep the bag inflated which is why they go down slowly.

Yours goes down fast though, so i wonder if there is a problem with one of the height sensors or something.  If I get time I'll have a look at the help files on Rovacom for some info.

Meanwhile, di you have the factory alarm or an aftermarket one?

lyndon:
The vehicle hasn't been modified in any way so I am guessing factory fitted alarm. Just spoek to two Landrover dealers. One wouldn't help unless I booked it in, even though its quite easy to explain whats happening. Second says it sounds like there might be corrosion on the base plate causing the seal to break. Says its about £100 for the part and one hours labour to fit plus vat so just shy of £200.

Its doesn't go down that fast. The strange thing which nobody has been able to explain is why it take ten minutes before it starts to leak. Once it starts going down it takes about 5 minutes or so to go down fully. The airbag is sound no holes, hense why the dealer thinks its the base plate. I also think personnally it might be the clip holding the airbag on at the bottom may have come loose. Is that feasble ?.

Range Rover Blues:
The clip doen't go intot he air, but a new bag is less than £75 nowadays IIRC and yes about an hour to fit yourself ;)  Not convinced by that story though :-k

Here's a thought.  Park up and disconnet the ECU somehow, pull a fuse or whatever it takes and see if it still goes down.  Either the air system leaks, possibly as you thought once some of the pressure goes a seal somewhere opens up, or alternativley the control system (electronics) is opening the valves.

Does the system still work as nomal? going up and down with the alarm fob etc?

lyndon:
I don't have the alarm fob device for adjusting the level. I am sure it is an optional extra I havn't bothered with. If I am right you can make the vehicle sit right down on the bumps for loading and unloading with that. It works fine though with the dash board switch. Goes up the extra few inches and comes down again great. Its only with the ignition off you notice anything different. The air is definatley coming for the bottom of the NS airbag. It can be quite easily seen when wet.
