    I've just returned from a drive to Belgium without any trouble (Mercedes eh!).Thing is....the day after,I got into the car and noticed water/liqiud running down the nearside passenger footwell.I removed the carpeting :-( to find 'a lot' of water soaking it and the underneath metalwork /heater blower ducts.A local Merc specialist reckons it is the water heater diaphram thats gone.He wants £110.00 to sort it & with a £200.00 'B' service due,it'll kill me financially.
    Can this be repaired (if it is that...what do you think?).Would it be easy enough/cost effective.

    thanks in advance for any advice.

    Tom

    Really don't know what you mean by" heater diaphram" ?? Do you mean the heat exchanger (small radiator) or what?? the duo valve 115 on diagram sometimes goes faulty but doesn't lead to leaks.

    If the heat exchanger is to be replaced £110 seems strangely cheap to me?? If its just a crack you may be able to bodge a repair using metal epoxy but you would have to drain the system first. Difficult to know without seeing what's wrong. Its not just the air con drain tubes leaking is it? Does the leaking liquid look as if its got antifreeze in it--slimy to touch and smells different? One more very important thing--- check your engine coolant level. If the leak is large you may have lost some.

    the fluid just seems to be water only from what I can see.The coolant level looks right too!

    Maybe just your aircon drainage tubes are blocked or leaking then. I am not familiar with the layout in your model so maybe some other clk owners owners might like to comment?

    Heater matrix is usually a major job.It usually requires a major dash stripdown...Im surprised he only wants £110 for it, if that's the case.

    Unless the mech thinks it the matrix o-rings item 200 that are leaking as opposed to the matrix itself? but i would say its still a full dash strip, this used to be a common fault on the last shape range rover.

    If its the matrix itself that price is a bargain beyond belief:)
