Hello,
I recently purchased E60 530i Sport with only 30k miles. I assumed the dealer changed the oil prior vehicle delivery. My iDive System indicates 14k miles to next the oil change. I noticed some fluid patches on the my drive way. I am trying to understand if the spots are from engine oil, transmission fluid or some other fluid?? I checked my engine oil level. It?s little bit over the max mark. I don?t like this at all. I have been keeping eye on the oil level and it does not seems that I am loosing any engine oil. The plastic cover under need the car has some wet spots somewhere between the passenger seat and engine compartment. Hard to tell exact spot / source of the leak. Now my concern is the transmission fluid, which I am not sure how to check. How difficult is to differentiate the engine oil from the BMW transmission fluid? Any comment / advice are greatly appreciated. Thanks, Vince |
It's not that hard.
Motor oil is VERY black. Transmision fluid is lighter and tinted like red or green etc. You also have power steering fluid and anti-freeze. The best thing is get under there and check out any wet areas. |
I would say it's condensation water from the the A/C --> if so, harmless.
|
get it on a ramp and get the undertray off and you'll know what it is. the location says tranny fluid to me, had it on 2 different e60s. the sump under the gearbox cracks easy, made of egg boxes.

Confirmed:
The fluid is actually transmission fluid.

Mine was replaced last week. The sleeve was the leaking point.
|
how easy is it to replace that seal/ sleve cuz im leaking lil spots on my driveway and like you guys am having a hard time telling if it is oil or tranny fluid,
|
it could also be an old transmission pan gasket that's leaking.
if you can't identify the source, take it to a shop. |
another thing is that the drip only happens while the car is running, if I turn car off the drip dries up, what color should the fluid be if it was transmission fluid that is coming out?
