Hi guys.

My GTS has been into Lancaster maserati today for a brake fluid change an A/C re gas.
After re- gassing I've been told the compress has excessive play in the pulley wheel.
I've been told not to use The a/c as it could result in the belt coming off and the car breaking down!
Anyway, been quoted £2500! Obviously not happy to pay this amount.
Does anyone know where I can get the compressor re-conditioned or a replacement unit?
The car has only done 26000 miles do not chuffed.

Any help greatly appreciated.
Thanks

Compressors do seem to be a weak point in the brands reliability.

I am sure Matt posted last week that it is the same as a family hatch...Renault or Vauxhall.

here you go.

As I posted it in another thread, might as well post it here too:

QP/GT AC pump, same as Renault Megane (beleived to be a 2007 but will need to be checked, I was told this by one of the well respected sponsors/service centres on SM)

Can be had for about £250 new, you have to change the clutch assembly off your old one and possibly the pulley too.

Thats about a £2k saving on Modena prices!

So, my 2011 Gt would be the same as the 2007 Renault compressor?
Ordered from Renault main dealer?

This is a common failure mode with this compressor design. I had the same issue with my first QP. I sent the old compressor off to be reconditioned, but they couldn't repair it. I ended up buying a new one from Eurospares for about £700. I didn't discover the Megane thing, but I did discover that the same basic Delphi compressor is used across loads of Maseratis & Ferraris, but it's listed under multiple part numbers despite the same mounting points, electrical connection, pipe connections, pulley, dimensions, etc.

I found Eurospares was selling something that looked right, but listed for a different car, so I took my old one and compared them side by side. They appeared identical so I bought and fitted it and all was good.

They seem to have one at the moment at £725, listed for an Enzo, but it looks like the usual Delphi to me:
https://www.eurospares.co.uk/parts/...tarting-motor-and-a-c-compressor-36854/263172

Eurospares seem to have no knowledge of the interchangeability of these compressors, but if they fit, I can't imagine why they'd have different internal specs, outputs, etc.

Any competent mechanic will be able to fit these. No need to unbolt exhaust headers, though access to the pipe unions is tricky. Get new seals and a dryer from Lancaster.

Oh, and I just realised - the advice about transferring your old pulley over to a Megane compressor is not fantastic (assuming it is the right part) given the failure is not in the compressor, which is stilll working fine, but wear to the compressor housing "nose" that the bearing sits on. I suspect that the wear is caused by a failing pulley bearing or, a slightly loose pulley bearing from new. My pulley bearing seemed fine, it had only done 45k miles.

I looked at cheap ones from Hungary, but they didn't have stock of reconditioned ones and I didn't want to risk buying a Chinese copy (you can find them on Alibaba), so I went with Eurospares.

By the way, if it's quiet with the a/c off, you can drive it, so you have a few months to fix it.

Lancaster take the pi55 on labour rates and will reduce that if you ask.

Anyway, yes, very common. I replaced mine with a recon unit from Compressor Express in Hungary. I was really impressed with the compressor and the service. Recommended. From memory the Renault option doesn't work for the reasons stated above.

Contact Eddie at Christian Lewis Performance for advice on compressor interchangeability.

Mine went on the Strad at 20k Miles, same nose bearing failure.

My local (Gloucestershire) garage replaced the a/c compressor on my 2009 QP for £820 inc.
The part was £522 - I think it was a Delphi 10662. Might be different for a 2011 GT, of course.

That's the one! Similar price as well, from memory, and more or less the same for fitting and gassing (Grimaldi did mine).

Well, has anyone got the Renault part number? Wouldn't take long to find the best suppliers from that.

Hi, I have the dreaded air conditioning compressor problem on my QP. I am also on the Herts/Essex border. Can I ask, how did you get on with Subzeroac?

I have also used Compressortech, they were located 3 units away from my old work premises. They are reluctant to rebuild maser compressors but they can supply new.
