Case of the X5 mysterious leak (Part II)

dvs · #1 08-22-2007, 07:56 PM

ok so i finally got a chance to put the X on the lift to see where they mystery leak was coming from.

as i look under i expect to see brake fluid leakage but to my suprise i do not see any.
seems that there is small traces of transmission fluid on the pan but just seems not enough to justify the small puddle in the driveway.

so i decided to clean the bottom of the pan or cover? and give it a couple of more days to see exactly where the dripping is coming from.
also noticed there was some leakage coming from some sort of black sensor module. dont know what it is maybe someone can shed some light as to what its for. (see below for close up)

i will update in a few days if i can find where the leak is coming from

Nice lift guy! How much did that cost you? I've always wanted a lift. There is so many things that I could do to any car if I just had the lift...

wasn't too bad, total it cost me $2,000 for the lift and i installed it with some help from friends as it was heavy to lift.

Looks like the connector for the tranny electronics.

bump...
I never did find the leak as it "went away...."

but as of Saturday noticed it was leaking again from the same spot. So I decided to bring her in today to get it fixed! Later today service calls me up and says it’s leaking from the "mechatronic sealing sleeve." Also covered under CPO

seems it’s a known problem found this Bulletin today on the web

BMW: 2000-06 X5 WITH AUTOMATIC TRANSMISSION
SUBJECT: Fluid leaking from the transmission oil pan may be caused by a faulty O-ring and/or a faulty "mechatronic sealing sleeve." The sleeve and O-ring can be replaced after removing the transmission oil pan, and the bulletin includes basic instructions and all the part numbers need for the job. The original transmission fluid is specially formulated for BMW transmissions, so it's important to use the correct fluid for refill. Bulletin SI B 24 08 06

Hope this fixes my issue
