W210 / R230 Aux coolant pump leak - a common fault?

[Conor]

Hey guys,

I've just had the cooling system pressure tested on my R230 and the aux pump is leaking (part A2308350264)..

I have a couple options:

* Buy the OEM part new for €250 from MB
* Buy an old one pulled out of something that was parted out etc for about €50.

It a very easy part to access and exchange and my decision hinges on whether or not this is a common part to fail or not.

If it is a common failure (car at 80k miles) then I'll spring for the OEM new, but if it's a freak failure on mine then i'll just pop in a used piece and see how long it goes.

Note that this piece isn't a critical part of the coolant system and is only powered on after the stops, very little coolant is lost from the leak, but I just noticed it a few times.

Any ideas?

Just ordered a new Vemo part delivered for £54 delivered to Ireland. Will see how it goes.. but happy to take the chance on a car that will do 1000-2000 miles per year. And it doesn't leave you stranded if it goes boom.
