I’ve had some issues with the air con for some time now and the self test keep coming up with the 4FA code which is the V71 recirc motor. 

 

My issues are no cool air at all and a strange whistling noise from under the bonnet. However I don’t think these relate at all to the V71. 

 

Does anyone think its it’s worth changing the V71 if it seems to be working? 

I can select recirc and it clearly motors and changes the airflow with none of the nasty noises other people have explained so I’m sure it’s fine. 

However if it is sending some dodgy electrical nonsense that it shouldn’t be, could it stop the air con from working? 

 

Im bored of this fault now but don’t want to just throw money at the thing. Could be compressor, could be V71, could be some other sensors somewhere. Boring.

V71 is the actuation motor.

 

You could get a clicking from behind the dash and-or the air recirc flap wont work.

 

Depends on what the fault code is.
