    I wonder if someone could oblige and post a schematic of the power steering components off a w211?
    I took my car to an indi today and he told me there is a valve body that is failing,Im interested to see what it looks like apparently it's a dear enough part.

    If it is only heavy at low speeds, you may have a problem with SPS (speed sensitive power steering), which was not fitted to all cars - a solenoid on the rack is a clue.

    It really just around town, motorways and at speed no bother, it's just that I seem to have to bring the steering back centrally that bothers me , it is a 2004 w211, the indie looked into the engine compartment as opposed to under car so It seems solenoid?
    thanks

    There are 3 known faults that can happen on this,,it could be worth a STAR read out

    Make sure it's not just a combination of poorly inflated tyres, worn ball joints and badly set up steering geometry. I speak from experience of all the aforementioned..... :)

    You've probably already covered off all these but I thought I'd post just in case.

    Tyre pressures Ok and ball joints replaced last month for MOT..actually I was starting to think something wrong with B/joints as the steering problem started after their renewal, but it was coincidental,
    also the tyres are standard fit so no drag off oversized tyres.

    What about the steering geometry, do you have a print out from the 4 wheel set up?

    No ..I have no reason to suspect the geometry as I have owned car since nearly new and it has never been so much as kerbed,I genuinely think it,s a case of fair wear and tear.
    looking on this forum ..I must have the only e class in the world that doesn,t pull to the left :)

    I think your best bet is a Star test (as Malcolm advised) completing and if that reveals nothing then spend the £70 or so on a good 4 wheel alignment.

    Don't know how old your 211 is or how many miles covered but geometry can be knocked out by a pot hole or simply dropping off a kerb.
