#1 of 78 Recent cold temps problems
Feb 06, 2007 (3:42 pm)
My "oil separator" cracked the gasket in the engine yesterday. Today, it is a $1200+ repair bill. Has anyone else experienced this before? Something about moisture in the oil... Any chance of warranty (I'm post 50k miles)

Ouch! I thought German cars could handle cold weather?
A separator should be able to handle a little water so it sounds like a serious malfunction.

have you heard of this before? Can you tell me more? There were three cars yesterday suffering the same symptoms at the dealership.

I've heard of separators becoming blocked due to low temperatures. We'll need to hear from other X3 and X5 owners to know whether anyone else has experienced this.

A similar problem just occured in my car, but it is the 330ci, and we are now looking at a $2400 bill. We were told that the moisture value froze, caused a back up and then blew out and now they are cleaning oil out of every nook and crany of my engine. The dealer indicated that they had treated about 15 other cars with simiar problems due to the cold temps in the past 10 days and they are trying to determine driving habits that could have caused. But it seems to me that this was a mfg defect, especially now that the replacement part is insulated to prevent in the future.

Driving habits? Such as driving in cold weather? Wow!

The driving habits...hmmm. I remember the mechanic at the dealership referring to how few miles I drove my X5. I told him it was around 6 miles round trip to work everyday. He suggested that city driving was not condusive to cleaning/burning/circulating the oil properly and it thus accumulating moisture. I think that falls into the driving habit category. Does that make sense to anyone?

Sure it does. But it also falls into the category of "normal driving" and I would not reasonably expect a separator to fail in such a catastrophic manner under normal driving conditions. Just a thought!

1. What is an oil separator on BMW's? Have never heard the term before.
I'm looking at a 07 x-5 v-8 and got concerned looking at the postings.I spend a lot of time driving in northern WI,MI and MN. Thinking I should order something else.

The host seems to do an excellent job of explaining things, so I'll defer to that person.
