Yeti air conditioning issues

[mike ryan]

So I have been asked by a customer to change his air on compressor on his yeti 2.0 tdi. When I looked at it the clutch has given up on it. The design of clutch for the delphi compressor is not a direct drive. It has the arms with some dimples that are designed to locate in some pegs. This acts as a fail safe in case the pump fails and doesn't strip the belt. So I did get a spanner on the end of the pump and it is still free.

So the pump appears OK but other forums suggest that the clutch only fails when the pump is gone. I was hoping to not change the pump if not necessary. Has anyone else had issues with this kind of clutch? I know that they are fitted to many vag models so hoping someone can help. Do I change just the clutch or the compressor and do a regas?

Cheers Mike

It isn’t a clutch, it is a shear plate; the compressor is a modulated delivery design and they are highly unreliable. We replace Delphi and Sanden with Denso and we have had no repeat failures. The shear plate is available but will fail again if the internal fault isn’t rectified and with a brand new Denso DCP32045 available for £190 there is no point.

The shear plate is not like the one you pictured. But I take your point about the compressor and will quote for a whole unit instead. What is it that fails as the one on the car still turns free as a bird with a spanner on the end of the shaft?

They fail internally and the valve fails, we just fit new Denso. I recommend searching for “Denso compressor oil balancing” first.
