I'm trying to get a handle on a vacuum leak on my 2002 CL55 AMG. I don't understand what parts these letters refer to and I could sure use some help. I disconnected and reconnected each pipe after doing a vacuum test and my results are as follows:

MKC Rises but drops fast
FT Holds good
BFT Zero no vacuum
TD Rises but falls slowly
HECK Rises but falls slowly
KAF Rises but falls slowly
SK Zero no vacuum

My drivers door lock wont open or close, but I do feel that there is vacuum there because it closes on it's own and it is sometimes hard to open the door by the lever, and then it closes immediately afterwards on it's own. The roof won't open, and the lumbar in the seats won't work at all.
So I really need to know where these lines are going to
Thanks.

Where did you get that test result from?

Lestere

I connected to each hose individually and I used a hand pump vacuum with a gauge to pump vacuum from each pipe.

I really need to know where the pipes go that are connected to these:
MKC, FT, BFT, TD, HECK, KAF.
i found some other markings on a PSE pump on this site but they don't match mine.
Thanks in advance.

BFT - Front Right Door
FoR - Right Rear Door (if equipped)
FT - Front Left Door
FoL - Rear Left Door (if equipped)
TD - Fuel Door
HECK - Boot Lid
KAF - Rear Head Restraints
MKC or SK - May be Central Locking

Thanks very much awiner for all of your very valuable help.

Its really strange that the right door is opening and closing fine with the remote(BFT) but shows zero vacuum on the gauge, while the left drivers door (FT) doesn't work at all but holds a good vacuum. Canada left side is drivers side as far as I know

Yes, Canada is left side drivers side....I believe FT stands for Fahrer Tuer (Drivers Door) BFT - BeifahrerTuer (Passenger Door) Just guessing...
