Yes, soapy water would also work. I need to test the valves on this car, make
sure that is not an issue that was maker masked while I had the gauge set
attached.

Some are. I have replacement valve cores for my former W140s. I had bought a
couple low side cores as a precaution when I found one leaking. They might have
stopped doing it on later models. Either that or the whole fitting can be
serviced as a part, I’ve got a couple of those, too.

I would think so. That was on my Ford Ranger. I don't think the valve cores are
replaceable on Mercedes.

Regarding the valve core replacement tool, I bought one to use on my 124
Mercedes, only to find that the low pressure valve does not have a
replaceable core. Wasted time and money.

I had one like that and it was the valve core leaking. That's where the dye
goes in, so of course it glowed. Sniffer found it right away.

The complaint that seems common with the cheap ones is unexpectedly
that they are *too* sensitive. They start beeping and blinking in the
general under-hood area and you can't pinpoint where the leak is.
I don't know how much to trust online reviews though.
I don't want to use UV dye because

Shine the UV light on the drain underneath.

Is that because you cannot see the entirety of the evaporator or for some
other reason?

I have a clone of that, paid about $30 on eBay or Amazon. Works ok. Used it
last night to find that the compressor front seal is leaking on my '95 E300.
They are probably not as accurate for small leaks like a professional tool, but
useful enough for the occasional leak. I've confirmed one
At the time I bought it (a couple of years ago) it appeared to be what
the pros were using so that is what I went with. As many cars as I do
AC work on I wanted something accurate.

Thanks -- that one is a lot more expensive. I guess worth it though if

I imagine these are all about the same. Here's the one I got. It's adequate.

These work too.
Anyone have one of these? Is it worth it for occasional DIY use or is
there something else that's a better value?
