Mine went in for the same oil leakage on passenger front a couple weeks ago. They replaced the seal on charge air pipe from tbrocharger. replaced charge air sensor and did reprogram... all good, oil leak fixed.

CEL came on last friday though brought it in Monday, with 4b3c (exhaust gast temp controller plausibility) just got it back.

they had no clue what to do so they replaced Exhaust Temp sensor (13-62-7-805-606) and reset. Said they 'think' this will work but needed to drive it for 60 miles. No way i was gonna let them drive it so i took it back and we will see if CEL comes back on after 60 mi...was in svc for 3 days m-w...at least SA was honest and said they had no clue...just wait and see i guess....

I remain concerned that they are thinking replacing a seal that is designed to hold air will contain an oil leak!

There should be NO oil in the air system.... Oil gets there from a turbo issue wherein oil that is supposed to be lubricating the turbos is leaking from a seal and being injected into the air flow.

I would be concerned with burned oil and the impact on the emissions system...

My 2 cents.

Yesterday morning I got CEL come on (all of the sudden on my way to work)... Drove straight to my BMW service department. Today got a call - turbo-intercooler hose leaking, they ordered part and should get it installed tomorrow.

No other symptoms - no oil leaks, no changes in engine's behavior (power, torque, etc were normal).

Funny that the 1st loander (a 535i) died on me too (low coolant, engine went into limp mode - did not allow to spin off above 2K rpm)... Now I know what the "limp" mode feels like (it is when honda civic with 4 passengers passes you on the highway entrance ramp and you can't do a thing about it )

Can I say I found this humorous?

1. "All of a sudden"? What, do they sometimes come on slowly, maybe fade in like a slow dimmer?

2. "On the way to work".... So going home, or to lunch, or just driving around aimlessly, are entirely different CEL situations?



Hope it resolves

I appreciate your humor and nitpicking to wording, but it was sudden to me, and I was late to important client meetings (twice! - because next day's morning the loaner broke on me on the way to work), so wasnt that funny when you are presenting, 20 people are waiting for you to show up...

Sounds like a different issue. Mine as well as well as the 2 others on this thread had oil leaking through a bad seal on the charge air hose. Per Ard's replies, why there was oil in there in the first place is a concern, and hopefully they just didn't put a seal to contain oil that isn't supposed to be there in the first place.....Interestingly, when I look on OEM.com with the part numbers that dmfelger provided, they show different part numbers for the seal on X5 units produced before 4/09......Makes me wonder if they realized they had a defective part and changed it. I bought mine 2/09...Hmmmmm.

Well, sounds like your problem is with intercooler hose, which is different. Mine did not kick off a CEL. I just noticed the oil on the ground.....

Good luck!

got a call from SA, he said they fixed it. I am picking it up tomorrow and will post what they have actually replaced (will try to get part number too)

cant tell you how much I missed in during those 3 days it was in the shop...

Can I ask which hose was leaking/replaced?

I think mine is still leaking oil. Saw a few new drops in the driveway....I'll keep an eye on it for a couple days to make sure it isn't just residual oil from previous leak, but I doubt that will be the case.....I'll bring it back to dealer Mon or Tues....
