Correct name

[richball65]

Who can tell me the correct name for the two valves in the plenum chamber for the aircon that are known to have manufacturing swarf stuck in them.


Searched in vein

It seems to be known as simply a pump/valve unit. Audi would be able to identify it by it's actuator numbers..N175, N176 and V50.


(The pump/valve unit comprises the coolant recirculation pump -V50 and the left/right heat regulation valves (-N175/-N176).The heat regulation valve, left -N175 regulates the coolant flow fed to the associated heat exchanger for the right side of the passenger compartment from the engine cooling circuit.The valve is operated by the Climatronic control unit -J255 by a pulse width modulated voltage signal.)

Thanks c4a5er, seems to be a known fault with them

Read the pdf doc that's near the top of the search - can be swarf, can be other things.

Looks like I need to get my outside air temp sensor sorted first before I go any futher
