| From France How to changing a suspension compressor |
|
Hello everyone.
First, sorry for my poor english (thank you Google for translation tool..)
I just returned from Corsica with the compressor suspension out of order. I was in Ajaccio when it happened one morning to start by standing on a sidewalk (it's a 4x4, I thought we could, but no). The workshop of the concession of Ajaccio is closed (no reopening date set, we must not fail in the corner, it's just my luck) and do not have neither the time nor the inclination to climb Bastia up, I drove like this: Special Programs are disabled "default suspension" accompanied ding dong from 50 km / h. Luckily he stayed normal height. I made an appointment to Marseille for a test fault codes off the boat. Dixit the foreman of Marseille, this is the exhaust valve is stuck (the spring is a little weak, I read here on this forum). Well, thanks to a french member of french forum. I found a new compressor at a good price.
Does someone here already? There is no need for the IDS but how to flush the mess before things apart, including (132 psi in the face here may be very bad).
If there is nobody who knows, I still have the option of a subscription-day workshop in GTR, which would seem prudent.
Other decision : to buy a fautmate FCR (88€ and 2H30 to wait for diag in France !)
Thank you in advance

easy to change! left rear wheel remove the 3x10mm bolts and remove the lower cover,just remove the pipes 2 at the rear no pressure in these pipes and 1 to the front this may be under pressure? remove the 3x 10mm bolts and remove the compressor and bracket together.swop the bracket to the new compressor and refit to vehicle
start the vehicle and all should be ok.

Seen like that it seems easy. I was just concerned about the pressure inside the pipes. I would put eyeglasses and gloves for safety !
Thank's you for your answer

I just changed the compressor. The new one has worked 2 or 3 seconds and stopped. The car is still in default and now it is down therefore practically unusable.
How can I get out of this problem?
I want to buy a Faulmate FCR but my money is not inexhaustible.
Thank you for all your help

I tested a few seconds with the compressor motor relay on the manip explained by Wiggs. It works.
I did a hard reset but the fault code is always on. What to do until the solution Faulmate ?

Looks like you need to clear the fault that will be registered, you need to either get it in to the garage or find some one who has a faultmate / autologic who will oblige. Good luck.

| I'm stuck, stuck, stuck, and so one...... |

I read everything that has been posted on forums and I tried everything. Without results, I'm stuck. And I'm sending mail from several days to Blackbox for my quote on Faultmate FCR30 + Canmate (one for me and one for a friend). I have no answer yet. They are in no hurry to sell?
Otherwise it's going to the local dealer but I don't trust.

The faulmate received this morning and put into service immediately sends me two error codes on the suspension:
C1A13 for 'venting gallery'
C1A36 for the exhaust valve.
If I consider that it can not be the valve since I just changed the entire compressor is the 'venting gallery' who is the prime suspect. Besides changing the pressure sensor and the 'venting gallery', I do not see what could be here. I can not imagine having the misfortune of a new valve defective.
Meanwhile any ideas, I disassembled, cleaned and checked all the connectors distributor in the compressor housing, those in the overflow valve of the rear axle and those of the control module in the cockpit. I checked the pinch of the various pipes and muffler. No problem everywhere and my back endlessly.
The problem is the pressure gauge on 'venting gallery' ?
or other

The exhaust valve block are 2 seperate blocks on the front and rear. I believe you refer to that as the "overflow valve".
Could still be that one of those blocks is causing the fault. CLUB ILLEGAL CAR WASHERS

This 'overflow valve' is near the compressor, no ? It's controled by a pressure sensor ?

Its been a while since I looked at them but the Valve blocks are on the front and the rear of the car. Not near the compressor itself. If you follow the airlines you will find them. I believe the rear one is on the N/S behind the wheel.
Did you had a look at this thread also? http://www.disco3.co.uk/forum/post590456.html#590456
On page 7 you will find the air suspension drawing. Might be helpfull.
The air suspension can be a enormous pain in the ass.
I changed my compressor, rear valve and front valve based upon the fault codes I was getting. Then they checked all the wiring. Costed me € 1700. But the actual cause was a stripped wire shorting on the chassis......
Good luck!!! CLUB ILLEGAL CAR WASHERS

My D3 is running ! 4 days to spanish dealer !
Neither better nor worse than the French dealer. Although I arrived with my own diagnosis he wanted to redo all the tests and gave me a bill of 950 €! There were a broken wire in the sheath at the front. They watch their computers too much and don't use enough their head and a ohmmeter ! Rascal !
