    If the leak is coming from the bottom of the strut - Replacing the O-ring may fix the leaking strut.


    Cheers and post back if it works,

    My left front strut is leaking, it would appear an o-ring is bad, and I have a new air spring bag on the way. So, tomorrow or Wednesday I will be doing the same repair. Thanks for posting the videos. The main symptom I have is that the green, and then the yellow, car symbols will occasionally come on steady. When they do this the pump will not come back on until I turn the car off and back on. I've taken some long road trips and had it work beautifully, and the next day they will come on before I am to the end of the block. Very inconsistent! The only codes which have been typically set are for a slow leak, and for lower limit.

    Never had the system leak like yours on my VCDS

    I think yours is an easy fix, it may not be the struts, it may be the Valve Block and a few 10 cents o-rings may fix the problem. Don't replace anything until you tested with soap water and see the bubbles.

    Cheers and good luck,

    I have lots of bubbles at the bottom of the strut. I'm working on replacing the axle at the moment, also worn, as the bag hasn't arrived. When I checked the block it had no signs of leakage. But, the amount of leakage at the strut isn't enough that the system should have to work hard to keep the strut up. I'm thinking the compressor may be a bit worn as it appears the previous owner replaced the other front strut. Maybe they ran it for a while in that condition.

    Yesterday I got the new parts and replaced the bag assy on my strut. When I disassembled it I found the internal strut bumper had deteriorated and I had little pieces of red rubber everywhere. The bag itself was not torn and the o-rings were intact but had gotten a bit square. Hopefully the rubber pieces are not now stuck in the check valve!
    My strut came easily apart, but getting it back together was more of a challenge. I had to remove the boot/cover so I could get enough grip on the bag assy and set the shock in place, and even then had to pound the strut forks against the ground so the weight of it would help get it back together. I also ended up replacing both upper control arms as the mounts were torn. Getting the pinch bolt off of those and the ball joint ends out was another bear.
    The number on my ATE strut is 15.1450-0090.3, I do not have the sport suspension. It did compress easily but I am hoping it is because I did not have power to it. I'm not used to a strut being so soft. It showed no signs of leakage.

    The strut doesn't need to be compressed, just pull the bag down to the rest ring and the cover over that ring. Make sure the new bag has the internal rubber (orange) in it and remove the old one.
