It's been a few days since I added the QMI stop leak and it seems to have worked in my case. The car was diagnosed with an internal leak probably at the front valve block
Ususally in the am the car would lean to the drivers side and there was no clearance between the tire and fender lip. Now after sitting all day yesterday and during the nite that leak seems to be gone. The car no longer leans and I can put 2 fingers between the tire and fender lip !! I don't know how long long it will last but it's all good now!! I ordered the fluid from Norway and had it sent regular mail it only took about 3 weeks. It's well worth the cost to give it a try.

Well just found a weeping strut yesterday. Ordered a bottle from Norway. We'll see what happens.

Car sat for almost 7 years and I'm sure that's what caused the leak.

New strut will happen if this doesn't work.
I'll make an update when I have tested the QMI product and have some results.
And for anyone who wants to know where to get it in Norway, here is the link. QMI Site

How did it go , did you manage fix it ? Sitting still 7 years is worse than anything .

Two months ago I put it in my Variable Roof hydraulics on SL55. It had leaked a lot of fluid and wouldn't go all the way up. Seems to be working great with no leaks so far. Also, put it in my CL500 ABC and seems good. Waiting few months before putting it in SL55 ABC. I noticed an ad from somewhere that states specifically for Mercedes ABC.

bneinast , no need wait for add SL55 , they all old now, and rubber seals all over the place inside,including hoses that dry up an crack need little help , your powersteering also add 40 ml to protect system.

@mikerx80 How did this work in your Lexus?

Tommyboy928

How did it go with your leaking struit ? was it fixed ?

V12orWalk

How did it work out for you? @Boo2boy

I used it at the same time I did a fluid flush on the ABC system. Prior to this, would get the ABC warning to visit workshop when driving hard, but ever since I did the flush and added a bottle of this stuff, haven’t had any lights come up and I’ve been driving the car harder than ever!!!! I’d say works like magic!

Hi All

Is this stuff even available anymore? I cant seem to find any available. Is there anything else that can be used in the engine and ABC system? I have inherited my uncles 2002 SL500 and want to make sure all seals etc are refreshed?

I am in the UK though so products may differ

Thanks

Hi, i know some has bought from Norway dealer qmi.no Norway and shipped to UK. Also spanish dealer has the stuff qmi.es , just amazing its no dealers in UK for sutch super product , not just for fix the leaks ABC , but engine teflon treatment is just super for protect engine moving parts, and also keep rear main seals in good condition.

finally looked to the end of this thread. I have a slight leak in my top hydraulics, takes several up/down cycles to loose enough to stop working. so far I have not found the source of leak. have not pulled out all the covers in the trunk.

it sent me to amazon to order. how much should I add next time my top reservoir is low? what you get is 3.4oz

MikeJ65

My recommendation is to add 0 oz.

Tommyboy928

can add 60 to 70 ml , but issue is get the stuff to the seals , if seals are cracked , it will not work, but will help all other seals that is not cracked . would be good idea change the oil in system also. 20 year old oil, not good.

porscheguy

thanks. recall I have been losing fluid constantly. takes several cycles of top up/down to lose enough that causes it to stop moving, up or down. seems I only have to add a few oz to bring back to the top mark on the tank. surprised I have not yet found where it is going. still need to pull out all the panels in the trunk.

so if I drain the reservoir only and refill with fresh fluid, is that enough? I would suspect the fresh fluid would find its way to the leak.

but willing to fully drain the system. any suggestion on the best way to fully drain and replace the fluid? then add the stuff to the new fill.

Tommyboy928

your leak can be roll over system behind the seats, is some people that made some info about this . if you can see the leak, is probaly there, and oil will be down below. is fairly easy to change seals they say.

Tommyboy928

Find me a SL55 that not use oil, like my car, is around 5 years now, i cant detect any oil use , stopped long time ago have extra oil in trunk for long trips.

porscheguy

Hmmm.....

problem is I have not found source of leak. suspect it is hiding somewhere behind covers. but over so much time just cant understand why I have not found it coming out somewhere. I have heard it is easy to replace seals .... if I can find location.

no suggestion about draining system and refill? so will just drain the reservoir and refill with the amount of sealer added before. hoping the sealer will find its way to the leak...

porscheguy

got sealer and ordered more Pentosis.

HOW DO I REMOVE THE EXISTING FLUID FROM THE ROOF'S TANK??????
