The X just died
 

I was accelerating to merge and the engine failsafe msg came on and the engine died.
I removed the key and tried to restart it.
It started but it stalls out whenever I let it idle.
So I can drive but I have to keep my foot on the gas at red lights so the engine wont die. The engine failsafe msg is no longer on but the check engine is.

Any ideas?

Check for codes anyway.... sounds like your CPS.

I sh*t you not, mine JUST did the same thing......

Solar flare?

FULL MOON.....or CPS....or both

Sounds like BS from CBS about CPS.

No, I was serious.....mine just died on the highway...it's at the dealer right now....happened 50 minutes ago

Wow... sorry.... Ain't that a bee otch!!!

My 03' 3.0 did it last August in stop and go traffic on the expressway , it started back up and turns out it was the CPS. Hasn't done it since.

Let us know what the stealer says?

My 01' 4.4i did the exact same thing yesterday morning after driving through a school zone. 3.5 hours later, flatbed tow to my mechanic. Battery is dead now as well so they had to push it into the bay. :confused: Is it a software timebomb?

Survey says......MAF, just received the call from my dealer

:dunno: Great...what's that cost? Let me guess...on backorder from Germany or special order, right?

My mechanic just told me he replaced the MAF this morning, fired right up. He let it run for a little bit, then test drove it, engine service light blinked while driving and died in 3 miles from the shop. Will start but not turn over?

No Charge....MAF was replaced in Aug 07

But my dealer (Wagner BMW) was a little confused about the DINAN MAF Housing until I pointed out that the actual sensor was still the factory one they replaced last year but in a different housing....BTW...My BMW dealer is awesome, they are just not an authorized DINAN dealer

I had a similar issue with my 4.4 last summer. CPS. Bought the part, changed it out myself. 10 Minutes, in and out.

:thumbup:

What the heck is CPS:dunno:?

Child Protective Service....... no.

Camshaft Position Sensor.... I think you have two of them Intake and Exhaust.

Just for clarification: I ended up doing the Intake side CPS only, so I can't speak to the difficulty of doing the Exhaust side. :nanana:

Thanks for the replies.
It was the MAF, as soon as the sensor was unplugged it held its idle fine. (I didnt drive it though)
A new MAF is 600 CND and its in stock.
Thanks again everybody.

Thanks:thumbup:!
