Hi Everyone, After a bit of advice. After parking up and walking away from my touareg (v10 ) to go in the garage heard a whoosh (like an airline bursting) looked around and the front of the car had slammed down to the ground and air was escaping from the front suspension (drivers side but both sides went down ) . Started engine to see if I could lift and lock suspension but it wouldnt let me lock it , so had to jack it up with a trolley jack without locking the suspension first, although the suspension didnt drop when I lifted it up . Found the leak the Air Suspension Residual Pressure Valve had snapped off the air bag top, managed to get the remaining / snapped off bit out of the air bag top . If I fit a new valve will the suspension just go back to normal or will it need to be reset ? Where is the best place to purchase a new valve think its part number 7L0616813B ? TIA

Loads on Amazon and ebay, not expensive either for a change.
Range Rover 4.4 TDV8 now gone and replaced with the opposite end of the pollution scale, BMW i3 electric car, one word, love it. Previous cars 4.4TDV8 Range Rover, 2006 Touareg 3.0 TDi (Superb Car), Audi Allroad 2.5 TDI (Also Great Car).
If youre old fashioned and still burning fossil fuels, MORRISONS fuel which is the best choice for all Touaregs.
P.S. Watch the mods here, they do dark and devious things when youre not looking LOL

I think these fail due to being a different metal so there is a galvanic reaction.

You should consider replacing the other side too.

Then slather both with some thick grease to protect them and clean and repeat the greasing each autumn before the road salting season starts.

As an update I bought 2 new valves and replaced both front ones . Not too hard a job and after the air pressure had built up they both rose up . Checked the suspension went up and down and took it for a test drive all good

Don't forget to grease them to prevent the galvanic reaction.
