First air suspension issue

[mannyo]

Parts, £25 delivered. I paid 2 hours labour charge for the fix to be installed. Certainly worth doing, in my case it appeared like nothing was wrong except the intermittent fault code. Fault code now gone, and all good apart from the air escaping sound which they are looking at as we speak. I hope its a dodgy connection from the last repair on the compressor and easily fixed.

You can DIY the repair, its quiet easy once you have the compressor off the car.

Could you share the fault codes you were getting if you remember, well, have them saved.
Also just for the sake of it Take a little spray bottle with plenty fairly and spray all the connections on all 4 shock absorbers as well at the same time.

Did you take the bumper off to take comp out or wheel and wheel arch off, bumper isn't it??

This the fault code that popped up shortly after I cleared them all.

01772 - Signal from Level Control Pressure Sensor (G291)
008 - Implausible Signal - Intermittent
Freeze Frame:
Fault Status: 00101000
Fault Priority: 3
Fault Frequency: 3
Reset counter: 64
Mileage: 207890 km
Time Indication: 0
Date: 2014.01.02
Time: 08:36:08

But looking back at the log I did a week after buying the car, it had been present for some months before I purchased it.

The compressor has to be removed, and the mechanic I used to change the part removed the front bumper fully, just for ease of access. Since he has the car again today, if I remember I'll ask him when he drops it off. The compressor comes out from the wheel arch side, but one bolt is accessed from the front.

Cheers Manny
btw, did you got my PM with reply to your questions, will be calling Chris now

And you say it takes 2hours while compressor is off the car??

[mannyo]

Yep, got your PM. At work, so not got the time to digest fully.

2 hours was all in, including removal, refitting and testing.

[M-A8]

Cool, no worries, I'm having time off work since 20th Dec till mid Feb so I tried to give you all the info possible to your questions.

Just finished talking to Chris, they will have to check if they or AMD guys, got somewhere on the paperwork sizes because funny thing 3.7 v8 has a slightly bend flex thats why all is custom made by AMD on clamps cos Audi wants I think 1k for both runs as one piece.
You've got all the details and all contact info there and Chris will expect a call from you tomorrow afternoon and you take it from there.

And it is £300 inc. VAT for both exhaust flexes supply and fit, 1.5h max I think

Thanks for all the legwork you are doing for me.

Got my car back this evening, he took the compressor off again and checked it over and says its fine. No signs of leakage from any of the pipes, so I'll see how the suspension goes.

No problemo Manny, just give him a call tomorrow afternoon, ideally after 2 or 4pm.


Where would you get specs of how long should it take to raise and lower suspension to see if there is already a wear/leaks which would slow down the operation??
I assume there should be a leak detecting procedure do0ne by the dealer (like used by commercial gas engineers on gas installation or at least this type)

Or it will throw errors straight away as soon there is loss of pressure ???

[mannyo]

The problem I had, which I thought was normal until I saw the car working as it should. Going from Dynamic to Lift, it used to take ages for the front to raise. its now way faster than it was before. I should have timed it before and after repair and I could have posted something.

I am not sure how, but I think using VCDS measuring blocks you can see the compressor output pressure. Repaired it should be 16bar, around 220PSI, before mine was running just 6 bar according to the mechanic, the other 10 were escaping round damaged piston ring.

[M-A8]

VCDS it is, will check it in a minute.

How long does it take now from dynamic to comfort etc, could you measure that at some point please??
