Just dip-tested the PAS reservoir, then dripped some on the drive next to the other stuff (how's that for dedication?!!).

Refrigerant contains dye to spot leaks and oil to lubricate the bearings in the compressor.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Just spotted a leak on the Cabrio! Gulp. Its ending up under the driver's door, and whatever it is is bright green. The coolant is the red stuff, is this leak possibly aircon refrigerant? Any ideas anyone?! :?
Pete
Yes Milleplod its likely to be aircon fluid, but also could be screenwash.
Is your aircon working, if not then this is the problem. Easiest way to eliminate screenwash is to fill up your screenwash reservoir and monitor.
Typically the issue is condensers. If you remove the PU (front bumper) you'll be able to see as there will be evidence of sludge and green stuff on the units. It could of course be a hose, but you'll need to see the problem. Refrigerant contains dye to spot leaks and oil to lubricate the bearings in the compressor. Again if your fluid is oily its refrigerant.
If you shine a torch through the front vents you might be able to see the problem that way.
New condensers are available from the OEM as well as OPC and third party. Just find out the part number and google it. Also available via suppliers on this forum - it's an easy job and Kwikfit will recharge at a fraction of the cost.
Ray :thumb:
Thanks for the quick reply Ray.
Yes, it seemed a bit oily.....
luminous
green too, and quite a different smell to coolant. Will go and have a root around and see what I can find!
Thanks again.
Pete
Yes Pete, it's aircon refrigerant. Here's advice on removing the bumper

Done it myself - well chuffed on the money I saved!
:lol:
Hi again Ray!
OK, have had a good look around. The leak is from a metal pipe that runs the length of the car under the drivers door. Its at a point where the pipe's supported by a bracket....I'm thinking this is a coolant pipe and the bracket's possibly worn through it? I
thought
the car had the red coolant in though....! :dont know:
Pete
Pete, if it's a thick pipe it's engine cooling water, if it's a thin pipe its refrigerant. Both refrigerant and engine cooling water run the length of your car.
When your engine is cold open up your engine cooling water header tank and you'll be able to see the colour and if there is any loss.
cheers Ray.
I'm leaning towards refrigerant! Header tank level is fine....and its a mucky red colour in there! This bright green stuff is stone cold, slightly tacky between the fingers and glowing spookily! The link you've posted doesn't seem to be working Ray.....was it a major job?
Pete
Pete,
Flourescent = Refrigerant.
Condenser swapout (both) took me a couple of hours including taking off the PU (bumper). Make sure you get the right part numbers - I think your's are quite cheap!
Ray
:thumbs:
This is interesting as I had a green leak a couple of years back and the air-con is still working, but maybe not as efficient as before... Is it a series system or parallel (for the two condensers)?
In other words is it possible for one to leak and the system in the other one to remain sealed?
Pete, I don't know why the link is down, perhaps it'll be back up next week??
Anyway, this will give you a rough idea - this is the link for a boxster

Good point Richard, I hadn't thought of that.
Pete take a small sample from your power steering reservoir and see if it's the same as what's leaked.
Ray
Hi Ray.
Just dip-tested the PAS reservoir, then dripped some on the drive next to the other stuff (how's that for dedication?!!). Its definitely not Pentosin.....not green enough, or fluorescent enough, by far. So I think we're back to refrigerant. Just one more question....if it is a condensor that's leaking, how come it drips under the driver's door? Or am I being stupid, which is not unknown?! :dont know:
Pete
Hi Pete, I'm not saying it is definitely the condenser - just that it's a common problem. It could easily be the pipe, you need to get at it somehow - perhaps on a lift. I'd go down to your tyre or MOT specialist and ask them to lift your car up for you. As most of these guys love fast cars I'm sure it won't be a problem for you
The Condenser shows a black oily sludge in the fins when it's leaking as well as green dye.
