Thats a result on the suspension.

The level sensors work by sending a pwm signal back to the module so if there was moisture in there that would definitely screw things up.

Hope you compressor rebuild is as painless.

compressor could also be running too much as it'll be constantly letting air out and pushing it back into the system to try and level it out when it's confused.

Compressor repair kit ordered, want to get this sorted before the compressor gives up completely.

Car is booked in with my friendly local independent VAG specialist for next Tuesday to have the compressor repair kit installed. I know I could do it myself, but the weather and time of year is not the best. The driveway outside the house is currently a sea of mud.

Good luck for the repair... Let me know how you get on. Just lift that is sometimes available or not at the mo, so perhaps the compressor is weak. For £25 I may just buy the kit and suggest the guys fit it when it goes in for the parking sensor replacement next week. Mine is 03 so an early one, lowing miles but 10 years old may need the piston rings doing.

Spoke to the mechanic earlier, he has fitted the kit and the suspension is back to full working order. The car now raises and lowers correctly, I'll test it myself when they deliver the car back.

He is bringing the old parts back to show me how bad it was, apparently air was escaping around the compressor piston because of damage to the old part and that is why the pressure was low. I'll post a picture of the old part when I get it back later.

Great! I think this could be my issue too. Did a big drive today and on starting the green light was on and went out after 10 secs or so but no lift. Then after 20 mins of driving, all functions there.

I'll get the eBay kit and suggest they fit as a precaution next week. If you don't mind me asking, how much/how long was the labour for this job?

Many thanks for all your helpful feedback.

Here are the pictures of the old compressor part. You can see the damage, it should be smooth all the way round and mine had some nicks from the outside and quiet bad scoring. Air was escaping round the edge of the part as a result of the damage.

I was charged 3 hours labour, Rick had to spend sometime cleaning up the piston cylinder as it was in quiet a state inside. Suspension is now working great which is a relief until something else breaks.

This is what I purchased, this is the original one. As you can see Andy has sold loads of them, each is handcrafted and tested before being posted.
