Here's a new one...
 

Here's another problem to add to our diesel's growing list. While driving with a few friends, our X5 gets a, "Engine Malfunction - Reduced Power," message. We just got done climbing a steep road, and turned onto a smaller hill when the message popped up. The engine did drop a few revs but didn't die or sputter. By the top of the hill, the message disappeared and I had get off, but it did seem fine then. I did notice a burnt smell that was the same as this morning, and I saw some smoke in front of the diesel this morning when it started up.

I wonder if this is contributing to our stalling issue too. :dunno:

I had a similar experience when I only had about 300 miles on mine. The dealer could not find anything. They suspected a misfire or fuel quality issue. I was on my first half tank refill. I switched to Shell Diesel and no issues since (~3000 miles.) I did not see or smell smoke. Let us know what the dealer finds. Good luck.

If it was cold then smoke on starting (from the middle of the car) may be from the fuel burning heater.

Smell / slight loss of power could be the particulate filter being burnt off.

It's happened to me twice.............before I could figure out what was going on, the light went away........all within 5-6 seconds each time............

Me too, about 1200 miles, 80 mph on highway, 5 seconds, then gone. No noticeable power change. Called dealer and was told it was probably a "computer glitch" and to bring it in only if it recurs.

Doesn't anyone :rtfm: anymore?:rolleyes:

Try page 139 of the 2009 X5 manual under the heading "Diesel Particulate Filter".

Funf Dreisig

I said it first, I said it first, :rofl: :rofl: :rofl: :bustingup

Happened to me on Christmas Eve!

It was fixed though - read my thread:

Ok but reading that manual is a torture! Requirng much interpretation on top of it's poor English translation.

But why would it trigger an engine warning if it's a routine operation. The manual doesn't say it could cause a warning or fault.

Read my thread - had that warning and the vehicle was flat bed towed to the dealerand repaired. It has been fine ever since.
