#10 of 59 What is an oil separator on BMW's by dhr48864 Feb 09, 2007 (2:59 pm)
The host seems to do an excellent job of explaining things, so I'll defer to that person. Replies to this message: tidester (Feb 09, 2007 10:49 pm) cat3126 (Feb 10, 2007 1:01 pm) ghall (Feb 16, 2007 1:15 pm)

Replying to: dhr48864 (Feb 09, 2007 2:59 pm) Feel free to jump in - it's your discussion!   In brief, the separator separates oil and gases emitted from the crankcase and recycles both of them.   tidester, host Replies to this message: cat3126 (Feb 10, 2007 1:01 pm) ghall (Feb 16, 2007 1:15 pm)

Replying to: tidester (Feb 09, 2007 10:49 pm) Must be part of the EGR system that takes crank case blow by fumes and cold start exhaust gases and returns them to the intake system. A basically simple system, seems hard to justify $1200 plus repair costs. Replies to this message: ghall (Feb 16, 2007 1:15 pm)

Replying to: cat3126 (Feb 10, 2007 1:01 pm) I just had the same thing happen to my 2001 X5 3.0. In speaking with the service department at my local BMW dealer it appears that due to the severe cold weather this has been an issue lately. With my X5 the seperator actuall blew at the back so there was not any visible sign of this issue under the hood.
#14 of 59 Oil sparator issue 3 times in 2 months by bali33 Feb 16, 2007 (8:29 pm)
My 2001 4.4i X5 have being in for service 3 times covered under warranty. This is a serious issue for BMW, but they seem to sweep it under the rug. No real fix by BMW (hence the 3 service times) for this problem when it gets very cold. No one should be paying to have this issue corrected in my view, whether or not the car is covered by an active warranty.

#15 of 59 BMW Oil Separator failure in cold weather by grassosf Feb 22, 2007 (5:54 pm)
Replying to: bali33 (Feb 16, 2007 8:29 pm) My 2003 X5 with 31,000 miles just broke down on the highway in PA (two weeks after being serviced and coming out of the 4year/50 M warranty). The engine hyrdolocked and would not turnover. When I called roadside assistance, nobody answered the phone to help. The failure was identified as a bad oil separation value. This part was covered under the 2 year extended warranty, but the dealer is requiring I pay $550 to replace all the manifold vent lines, plugs and sensors damaged by oil in the combustion system. They also informed me that can't find any parts and I should expect it to take about two weeks to repair the car. I have called the main office but they claim they can not help. Is this consistent with how others have been treated? Is their any other recourse that can be taken ?

Replying to: grassosf (Feb 22, 2007 5:54 pm) This is an inherent problem and a faulty BMW design. Once it gets very cold (single digit and below) the moisture in the engine gets frozen and causes oil leaks and a host of other problems. The core problem begins with the moisture build up. It is more of a problem if you drive short distances an the engine do not have sufficient time to get rid of the engine moisture. .....which may have cause my problem three times this season....what a pain. Another hypothsis is that ethanol than is mix into premium gas may contribute to addition moisture in the engine. In my view BMW should pay for your repairs. They have paid for mine, but my car is still under warranty. The service manager that I interact with have suggested that he/BMW is willing to pay for service due to the same issue in the future, even if my warranty runs out. Clearly they know this is a major brand damaging issue. Push back and have them pick up the bill. Good luck.

Replying to: grassosf (Feb 22, 2007 5:54 pm) I called the BMW NA office and was told that nothing could be done for me. I asked that they get me in touch with the BMW NA field rep (they call it an "engineer") to discuss this further. She suggested I call the dealership, which I did and have had noone call from the dealership.   I did find out that this was not a recall issue, even though it certainly qualifies in my uneducated opinion.   Isn't there a governing body that we can call to find out what qualifies as a recall issue?

#18 of 59 BMW X5 Oil Separator = $25,000 Repair by bmwnomore Feb 26, 2007 (6:08 pm)
2003 BMW X5 with 69K miles. 19K out of warranty and no extended warranty.   February 9, I'm driving my usual route to work and the engine hydro-locks and stalls (along with the steering column), before I finally bring it off on a side street to a safe stop.   Car is towed to my usual BMW Certified dealer and is diagnosed with a faulty oil separator, about $1,500. I authorize.   BMW service calls me back two days later to advise that the failed oil separator has resulted in liquid oil breaching the cylinders, blocking combustion, and ultimately caused a crack in the drive shaft i.e. "You need a new engine, about $22,000."   Not sure about post restrictions, so I'll pick up the story in the next one . . .
#19 of 59 $25,000 Repair, continued . . . by bmwnomore Feb 26, 2007 (6:13 pm)
I immediately contact BMWNA National Service who, in a very friendly way, advised that they could do nothing but that I should go through the dealership to contact the field represetnative.   Over two weeks and several conversations, I am advised that the problem is my fault for driving short distances at a time, like when I take the kids to school (I don't have kids) or when I go to the local Starbucks (Okay, I drink Starbucks but the nearest one is about 7 miles away and I always stop on my way to the office, about 20 miles away).   I am told that BMW has no obligation because it is our of warranty and it is not BMW's fault, rather, the government regulations are so stringent on exhaust, BMW has no choice but to design the engine to capture and combust these fumes, etc.
