D4 air con compressor control valve (RCV) number

[harlie]

Hi all

we have a 2012 D4 3.0 (last of the 6 speed) need to replace the RCV. Will DIY, I've done a VW previously.

Does anyone have a part number / listing handy please?

thanks

I think if you google it, there is a topix article with the part number on it

I love how they say “remove compressor”, like it’s a fine minute job

Many thanks, I have ordered part as per list.

Just a follow up:

I got a new valve for the AC compressor and Dad brought his car back down and we have a bit of time to swap the new valve in. I read all the horror stories about removing a million bits to get to it so I psych myself up and start - with the tyre.

• LH front tyre off
• guard lining remove

At this point I have a good look around and to my surprise The valve is facing outwards - one of the kids walks in and he's tasked with threading a hand in from under and fwd of the suspension - electrical connector removed.
He then gets a crash lesson on circlips and before I know it the circlip is out...

• valve out - new valve in
• circlip back in was VERY fiddly and took many attempts but we got it on.
• plug on

DONE!!

I do have a 2 post lift, and I'd say it's not possible to do this on the ground - well it would be extremely difficult. It would be a lot easier if the half shaft was removed as you could then get 2 hands into the valve - that may allow enough access for the job to be done on the ground.

In short - the RCV valve can be changed with only the tyre and guard liner removed (SDV6 engine)

That is awesome you've managed to get it done in less time than expected - miracles do happen! I had to replace my compressor and it was a bastard of a job. Would just stump up the money and pay someone next time. Well worth it though driving in 33 degree Sydney heat today.

Hi,
what was the reason for replacing the valve? What were the symptoms that led to the decision to replace it?

AC taking a while to start or going warm for expended periods and not cycling. Typical sign is it taking 5-10 minutes after startup to begin cooling.

Very good tip, these are exactly the symptoms I have in my car. I slowly started preparing to replace the expansion valve. Phew, I hope RCV will solve the problem in my case as well.
