Here is the latest update on my suspension problem.

Finally managed have the strut replaced today, had a friend come round with decent tools and after lots of cursing we got the new one in.

However

The front would still not rise, so we struggled on, he tried some output tests in VCDS and the car would not level.

We observed one odd thing that got us thinking, the rear right wheel was at the correct height, but the rear left went all the way up to the top of its travel. The sensor readings confirmed this, it was way higher than the other side.

After friend had left, talking to neighbour we kind of put 2 and 2 together and got the right answer it seems. Sticking valve in valve block, all the air was being sent to the left rear corner. Despite VCDS saying valve was closed, it cleary was not.

So got access to valve block and tapped it a few times with a hammer, and restarted engine. Observed that rear left corner now dropped down to correct height, and then the front raised up as normal.

So looks like it needs a valve block replacement, and the compressor is also borked as it keeps cycling on and off every few minutes as it cannot build pressure beyond 7 bar and has gone quiet noisy.

At some point with my friends messing around we have lost the basic settings, so the suspension needs re-calibrating.

So the current status is that the carr is sitting level now, needs a compressor and valve block and may not have needed a strut after all.

Alarm bells should have sounded when we went to disconnect the air line to the old strut and air came out under pressure.
