    Hi!

    One of the rear Load Levellers on my 1982 400i has sprung a leak (ATF)...
    I've spoken to a couple of shops in Germany that overhaul Konis, but none of them seem to be able to do these.
    Does anyone know of any shops in Germany or the EU that can service these?

    Cheers

    Esben

    Any mercedes specialist that has worked on a 300 SEL 6.3 or a 560 SEC should be able to help. The later uses a very similar setup.

    You could make a seach on "sphere citroën" and find some specialists dedicated to these hydraulic setups (it's patented by Citroën). The Citröën implementation is slightly different, but I presume the shops that fix pumps and pressure accumulators could work on your faulty part.

    All in all asking an old Citroën or Mercedes dealer for a specialist they work with could be a good idea.

    Hi!

    The leak is at one of the shock absorbers, and those are made by Koni. I doubt that a Citroën or Mercedes specialist will be able to help.

    Cheers

    He's saying Cit and Merc used similar systems. These specialist shops may have knowledge on how to fix, who can rebuild, etc.

    You could ask Mercedes M100 specialists who assist them in fixing their hydraulic monsters. I can think of Karl Middelhauve (based in the U.S, only exchanged with him by mail), Jean Christophe Branthomme (1 hour from Paris, very nice and passionate, but overwhelmed)

    Citroën specialists are more numerous : http://citroensmpassion.free.fr/ch9/ch090100/hydrauli.htm (I would bet on the specialist in Genay)

    Hello everyone,
    I just bought a Ferrari 400i automatic and I know that the oil has just been changed but I know nothing about the oil filters. So my question is, can I change the oil filters on a Ferrari 400i without emptying out the oil tank? if so, what would you guys recommend to do?
    Sorry to interrupt but I'm new and don't know how to create a new chat.

    Congratulations with the new 400i. I would be odd that oil has been changed and not the oil filters. Anyway, you can change them without any problem and not needed to drain the oil tank for that.

    They said they couldn't help, but dr-suspension.de might be able to. I have to send them some pictures of the damper.

    Cheers

    www.Forzaservice.nl were very responsive to me on repairing my leaky shock, although my question was more about replacing the self-levelling shocks with "standard" shocks, since I wanted to proactively avoid all the other things that can also go wrong once the shock itself is done.

    So still looking for ideas on that please...

    So they would repair the Koni self-leveling shocks from a Series 1?

    Based on the repair they suggested for my 412 I would say most likely, yes.

    Or, more specifically, replace the old shocks with new Koni's but keep the original springs and the rest of the self-levelling system functioning.

    Why there is no appetite/ability to get rid of the complexity of the self-levelling system and just have "basic" shocks is still a mystery to me.

    A cheaper, non-levelling system would be an interesting alternative. Any idea who might be able to sypply something like that?

    Hello Esben, I assume those are coil over dampers? Any (german) manufacturer should be able to sell you a set based on various measurements.
    Standard procedure. However, just be aware that TÜV might want you to have them approved. Mention that to (KONI, H&R, ...) when you call them.
