3.0 TDI Thermostat Part Number[s]? ...

[JulianHicks]

In March I created the 'How long does it take to replace ...' thread for the thermostat, which gave some interesting variations!

I've managed all summer with it running cool but winter's almost upon us.

Before I consider looking at this in more detail, can anyone who has access to parts info. indicate what the part number[s] is/are please? [I used to have a web url for A8 parts but that doesn't work any more].

I'm slightly confused as although I've seen pictures of the thermostat housing at the front of the TDI engine, I'm not sure if that's an integral unit [1 part] or a housing with a separate thermostat inside [two parts].

Thanks - Julian

Hello it is a plastic housing with the thermostat in it.
Try here for parts http://www.realoem.me/Audi/RDW/A8/
Looks like
http://www.realoem.me/Audi/RDW/A8Q/2...R/1/121/121001
059121111F
but please check with your own model year and engne code.

There is also another theromostat next to the gearbox which is FEBI: 38713

which is a more common point of failure on VW/Audis.

Hi Snapdragon, didn't see this until today. Thanks for the info, particularly the pointer to the parts diagrams.
