Dear all,
I would like to know if the new MB coolant is in Blue color instead of brown? Is it a common problem for W140 to have leaks from radiator, coz the warning light come on and off sometimes (low coolant warning)

How's the AC? is it got improved compare with the 94/95 model? which seems a money pit when the eva go south.

For the parking sensor(not the parking stick that come out from the trunk), is it common for them to quit working? The device does start but cannot sense

THank you!
