I don't  think that is the right one.

According to my parts list, that one, 12758381, was used up to 2005.

For 2006 the one listed in my Saab parts list is Part No. 12759394.

I have no idea what the difference is...

That's the one PFS sell for 380ish. Just tried Saabits and they don't seem to recognise the part number, but the other number they did and the part cost over 550  :o :o :o :o

Well as the noise is getting worse, I asked for some proper quotes, and I got these - both including VAT and delivery:

Saabits - Nissens  compressor+ belt 395.61

Partsforsaabs - OEM compressor + belt 405.23

Waiting for another quote yet, but I assume the Nissens compressor ought to be as good as whatever the OEM part is? So whichever way, it looks like I'm looking at 400 anyway....and that's before I've got my mechanic to fit it  :o

As I said before, speak to your local aircon specialists to get a price for the total job  ;)

WMSS were going to quote me but never followed up, so as you say might look for a local a/c place. Was going to source the parts myself and give to my mechanic that looks after our other cars but a turnkey job would be better.

I've had this place recommended a couple of times.

The guy I know goes to them, and says "Don't be put off by the first impressions of the premises" :o   I've not needed to use them, but I've noted them.

Yes, some of the guys will have access to trade prices for parts and will have the gas, kit and experience so you could end up paying a lot less than sourcing bits and getting another mechanic to do the work. It's very often the same for windscreen replacement, independents can get cheap trade prices for screens and fit them and still make a stack of cash.

I agree.  Most of the specialist type services provided by general garages are actually outsourced local specialists who are called in when needed.  So you are often just paying the local garage a markup.

There seem to be a lot of mobile aircon specialists about.  There was one near us in Harrow, but I can't find his details at the moment.

I also agree. For an aircon fix on my previous 9-5 a mobile specialist proved much the best option.

I'll try and contact that one that Will has posted above as they are not far away. But I also got this response from a mobile aircon guy that operates in Warwickshire:

"Hi Steve,
It will be the actual pulley and not the clutch that is probably going to be the problem. If the pulley bearing fails then it will throw off the drive belt and you could overhear engine, lose power steering and electrics.
It is not economical to replace the pulley as often they are seized on and require much more labour to swap out.
If the compressor needs replacing you could ultimately be looking in the 500+ bracket including labour, regassing etc.
I can come out and definitely confirm what is making the noise. Cost will be 49 for the diagnosis.
Regards
Paul"

Surely if it was the pulley and not the clutch, it would be rattling all the time. Not just when the aircon is switched on.   All the aircon on/off switch does is to operate the clutch, which connects the pulley (and the belt) to the compressor.

Well, not sure I want to pay him 49 just to come and tell me whatever it is, it's going to be more expensive still!!!!!! The 'throwing the belt off the pulley' scenario was what WMSS told me as well, but then they never bothered to get back to me to quote for the job.

So have emailed that CompressorTech company to see what they say. They are nearby so hoping I can take the car over for a free diagnosis first!!! ;)
