I've had my SL into the shop three times. It's leaking freon, but the shop
can't seem to find the leak. They found one fitting that had a very small
leak. They put enough freon in the system to get it to run cool, and told
me to keep an eye on it. Well, it's not cooling anymore, the pressure is
low enough that the compressor clutch isn't kicking on. Still leaking
somewhere, I guess. The shop I took it to isn't a Mercedes specialty shop,
but they have a great reputation and I would think should be able to fix the
Can anyone give me any ideas or pointers on this one?
The shop *should have* used a tracer dye when recharging the system. A week
later they would check with a UV light to see where the leak is... hopefully
NOT from the evaporator drain, a tube located on the passenger side under
the car. Did you notice an oil spot on your garage floor near the passenger
side?... that could indicate a core leak.
The dash, steering wheel, and driver's seat are usually removed for access
to the core, so keep your fingers crossed that it is not the culprit. If it
is, plan on replacing the dryer and any hoses etc at the same time... about
a $3K job at an MB dealer. It's not usually a heck of a lot cheaper
elsewhere, as they often do not have sufficient experience negotiating the
loads of wiring and other stuff encountered... thus more takes them far more
I am stunned they did not use a tracer dye if a leak was suspected... that's
