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 ???

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.

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??

Well well well....very interesting

Is the 16bar a pressure you would expect from a new compressor at any time as long is not in operation in that time ???

If yes then I'm f***ed

Started with starting a car and letting it set for 3 minutes
I've got a slight slobe side ways on front of the garage setting off car by 7mm on one site as read in measuring blocks.

Starting pressure on Comfort was 4.56 bar

[IMG][/IMG]

Then lowered it to dynamic and pressure after shutting off the valves was 3.25 bar

[IMG][/IMG]

Then lift and 2.28 bar

[IMG][/IMG]


NOW
From Dynamic (there is that slope issue if it matters) to Lift mode it took 1min 22sec !!!!!!!!!!!!!!!!

From Dynamic to Comfort 38sec.


BUT
On the road everything is quicker than that surely, I never was waiting that long, 38sec, or was I??

Then pressure on Dynamic was 2.28 bar

[IMG][/IMG]

...and comfort just over 3 bar
[IMG][/IMG]


Came across that fault during the check (could be after a recent lowering but I erased all the faults on the end), cleared it, the set to different levels and no error.

[IMG][/IMG]


So...am I in s**t ????
How should I refer to that 16 bar value and values taken 5 minutes ago as above???

Cheers another thing for me to start worrying about, honestly these cars are intensive on the wallet and grey hair production.

I'll run VCDS on mine to see what pressure shes pumping out on Saturday and get back here with the findings.

I'll take some readings from mine at the weekend,

Looking at that last picture.



The fault has occurred 41 times since the 18th of December.

I'll run through the same sequence of tests and see what happens with mine with timings, but I cannot do it till the weekend.

This is exactly what I said to myself when I looked at this post originally

Please do Del

Manny, can you post your live results??
