Uhmmm, how much is a replacement valve? Is it really out of the question to just buy a new one?

In 95% of the cases the leak is from 2 green seals underneath two plugs, these can be replaced with O-rings for about $0,10 each...

how does the ADS operate differently between US and Euro versions?

Not at all, exactly the same function, but Euro have the ability to raise the car 40 mm. An extra piston to extend arm for height control, very simple function.

Dennie,
Can you explain what you mean by "MAGNET RELAY" ?
Is it fitted to the the valve ? It is either a relay or a magnet - it can't
be a relay and magnet at the same time. Is it one of the 2 electro-magnetic
coils fitted to the valve ??? Attach a picture.

Confused,

fitzcarraldo

Thumbs up Top Hydraulics rebuilds early ADS valves (ADS-I)

GUSMB,

thank you for your many contributions to the subject - I deeply respect your efforts, achievements, and willingness to share your experience. If I recall correctly, then you stated at some point that you had to replace the O-rings you used repeatedly. We have already rebuild several valves that some shop in Florida has "worked on" by replacing the green seals with O-rings.

The seals in the ADS valves are made of the same material as the hydraulic cylinder seals for the top hydraulic cylinders, only the ADS valve seals are of a square shoulder design. We make custom square shoulder seals for the ADS valves out of a material that will not fall apart nearly as fast as the original seals, i.e., they should last for the rest of your car's life...

By the way, additives will typically make the original seals fall apart even more quickly, and we recommend that anyone with "stop-leak" type additives in their system flush it out VERY thoroughly. Euro version valves get resealed at the additional solenoid, as well - I have seen quite a few leaking from the solenoid.

I would generally advise against attempting DIY repair, as the perfect seals are not available over the counter (and we don't sell them), plus most people loose internal steel balls when opening the valves up.

GUSMB, you have done great, but one cannot expect that the average forum member is anywhere near as good with their hands as you are, and generally not willing to keep doing the same job over and over again.

We currently charge $110 plus $10 (domestic) shipping (or $40 for international Express Mail). We are not listing the service on our website yet, because we don't currently have DIY removal instructions. The first one who prepares a killer-DIY that we can host on our website, will get their rebuild for free...

First of all, I Think it is great that you guys exist, anyone who actually repairs something is great, despite MB, they don't repair anything, they replace modules...

Having that said, here is the rest:

No, have never repaired any valves or top hydraulics more then once so far, 5 years running on the ADS valve and I Think I have helped 10 more people online with this operation.

Yes, you are totally right abouth the seals, they are made of what I expect to be the same material, BUT, they have different funktions. The ones in the valve doesn't have a sliding function, simply a seal, anything that withstands the fluid should work.
On the other hand, the top hydraulics are pistons wich slides in the seal, would never use O-rings here and I have not, I use seals used for high pressure hydraulic pistons. This has worked so far. I have 3 more to do this Winter, the seals are about 30 SEK each if you find one that fits, Momentum in Sweden is very helpful for this.

Totally agree with you, a leak is a leak, fix it, additives is not a fix.
I have owned a Euro spec SL and currently a US spec SL, the ADS valves leaks at same place, have not seen any other place so far.

Agree and disagree, the two seals in the ADS valve anyone that is not a complete idiot and not in a hurry can do, as I said, I Think 10 people online has done this with my crappy English instructions. I did indeed take the whole damn thing apart and lost one of the metal balls, at the end I found a metal ball in a bearing in a old electric drill. BUT, no need to take the actual valve apart, I can nowadays remove a valve in 20 min, then just open the plugs, new O-rings and back it goes, leave the rest of the valve untouched.
The top hydraulics on the other hand, not complicated, but a Little more prying to get them apart and also to find the correct seals. But the main job is to get the damn things out of the car, replacing the actual seal is done quickly, but finding one that fits...

Conclusion, I do this because I want to learn, you never know if you could do it if you don't try.

You guys are a great way to avoid going to MB...
