Air con G65 pressure sensor

5 posts in this topic

My air con is "stuck" in econ mode so the first thing I did was to take it for a re-gas. "Your pressures are fine" said the Moto -Save guy "so it doesn't really need a re-gas and its unlikely to cure the problem- maybe the pumps gone"

 Being quite averse to such drastic off the cuff diagnoses I read about the problem and learned that the next most likely cause is a failed "G65 pressure sensor"  

The problem is I can't find the sensor and even after several hours of surfing I have not seen a clear photo of the whereabouts of this elusive component which I understand can be changed without de-pressurising the system. The thing might be hiding behind one of the headlights but before I start taking then out can anyone please confirm this ?

The car is a 2005 Allroad 2.5 tdi auto with the BAU 132kw engine. I would be pleased to learn  If anyone has recently dealt with this issue.. 

Thanks in advance

Hi!

Before you do that, can you hear/see the air conditioner pulley switch over when you ask it to use the air con?  You can usually hear a click and the engine note changes as the load on it increases.

No the pulley is not engaging as I've had the cover off to check.  Thanks for the pointer but I still haven't found the thing !  I think the illustrations are for a later model , Here are some shots taken when I had the bumper off - I wasn't looking for the G65 then though !
