Hi.

Anyone know exactly what this is? I have a leack from the bottom screw.... getting worse.
Is it expensive or an easy fix?
What exactly does it do would help to.

Thanks

Rob

I'm going to take a wild guess here. Since you don't have the year of your car in your profile, and you list your location as Zurich, I'm going to say that it is the Euro version of the infamous servo for the ACCII (Automatic Climate Control - Type II). Or a control servo for the heater (Euro version-without Air Conditioning). I believe that there was a thread in the last few weeks from either Yka or Pex, where they had similar troubles. I seem to remember that they were able to find some repair parts, but it was difficult.

Maybe, if I am correct in identifying the unit, you might be able to find more information that will lead you to a source for parts.

Best wishes in your hunt for the fix,
Scott

That is the recirculating/auxiliary water pump. You have the ACCIII system.

Look in the EGv107 Sticky for the on line service manual.

That's the auxiliary water pump, to help circulate hot water at low engine RPM. MB part number 000 835 69 64.

Hi Rowdie.... thanks for the help again.... any idea if I can make a temporary repair here by opening it and trying some gasket sealant?
I have one on order from US but will take 10 days to arrive :(
Are there any drawbacks if I open it?........ Cheers and have a great weekend

With an elbow pipe of the correct diameter you could temporarily remove it with no ill effect other than reduced heater efficiency.
