Feeling warmer already
Some people will know straight away what this is but I will let the others guess for a little while

Some kind of secondary water pump? For circulation water to the cabin heater matrix maybe?

Where does that go then? From pictures it looks like the D3 has a very similar valve block to the D2 with an integrated motor

Is it for the A6 then? Presumably not as it's in the D3 section....

It's for Webasto heater to circulate coolant when the engine is not running so that I can set heater to switch on timer and warm it up a bit before I get to the car. My D2 S8 had and A6 has aftermarket alarm with remote start that I can set to start engine on timer and warm it up so missing the option on D3 a bit. As the boiler is already there it would be rude not to add the pump. Not sure about aftermarket alarm, could be a bit more complicated to plug it in D3 with more electronics and not really necessary if it already has heater to do the job without engine running. On the other hand with remote start it works the other way too and can start it on hot summer day for AC to cool it down so could be worth investigating remote start as well especially as my D3 does not have solar sunroof.
Here is the link to the guide for it. Someone else uploaded it to the forum, I cannot find a thread where it was uploaded but searching on Google finds the attachment itself on this site. http://forum.a8parts.co.uk/attachmen...0&d=1537262841
