Hi all.
New here and to VCDS.

I have recently brought an Audi A6 allroad, 2007 3lt TDI. It has Adapted air suspension.

Everything seemed fine for a month or so when I noticed the rear was dropping overnight.

Having checked out the forums, I planed to replace out the rear air bellows.

Before I had the chance to do this, one morning I found the car would not pump up to its normal level. All the height options were greyed out and I had the orange warning light on.

I went ahead and changed the real bellows, but was unable to recalibrate, VCDS reported errors on all 4 of the height channels.

I replaced the rear left height sensor thinking that was faulty, to no avail.

Looking at the full auto scan, I now think that the valve block may be to blame, due to the references to the pressure sensor.

In addition, when I logged some advanced measuring blocks on a 30 min drive, the system pressure remained around 15.3 bar, voltages to sensors either 2.3 or 5v, and the compressor relay was turning on and off. All the 4 corners air suspension valves remained off apart from the rear left which did turn on and off a number of times although the height did not change. One thing that did strike me as strange was the accumulator pressure remained at zero through out.

Do you think I am on the right track, or have any other suggestions?

Thanks
Tony

Hi and welcome.

Nice first post, good description of the problem and an Auto-Scan in CODE tags. :thumbs:

I don't know that level control system well enough to make an informed comment here, but hopefully someone else does.

Right, I have replaced the valve block and can get a bit further now.
I was able to recharge the front axle, but not the rear, it kept failing with over temp errors. I tried again this morning, and got the rear charged. However, the pressures are not reaching that needed, only around 5 bar.

The first two codes make sense looking at the third, but, which sensor is it thats faulty? How to I find out without swapping them all, one by one?

Look in Measured Values First and foremost.

Look at levels
Look at temperatures

Are they some where near, are they plausible ?

Look at level sensor Links, are they fitted the right way around ?



Level Control is a simple system to understand and diagnose once it has bitten you on the bum a few times.


I have that T Shirt

OH !!! Stop replacing parts, that makes the job harder.
