Broken compressor drive plate.. repairable?
I bought my first Audi a few weeks ago.. an A4 Avant 2.0 TDi, B7 shape on a 55 plate, BLB engine code. It's a lovely car, but the air con doesn't work! So, I took it into Kwik-fit, they regassed it, and it still didn't work, so I got a recharge for free.
I then decided to get the serpentine belt off and take a look at the compressor. It's a Denso compressor, with a rubber cover over the internals on the pulley. I pulled that off, and had a poke around inside. I then realised that levering the drive plate with a screwdriver caused the whole thing to fall apart!
So the compressor looks like this... with the centre of the drive plate in the middle...
Then the drive plate looks like this, with the middle missing...
Its clear from looking at it that the centre of the plate has sheared sway from the rest of it, meaning that the pulley will never turn the compressor. All the rubber bits inside were present though, just not in the photos.
Does anyone have any experience of repairing this? Are the drive plates replaceable, and does the fact that it's broken mean the compressor is knackered? The compressor seems to turn easily enough, and I'd rather just change the plate and avoid depressurising and the cost of a new compressor if possible!
