BMW X5 Engine dies at the stop light

2001 BMW X5 3.0, 145K miles, generally runs good. Since last couple of weeks - when I leave home in the morning or work in the evening - it will die at the light or stop. Once engine is hot it won't happen again. I don't think it has anything to do with idling. I can be on stop sign for as long as I like and engine will continue to run, it's only when I try to move forward. No light lights up.

Any suggestions?

No light lights up... you mean the check engine light is not on? Do you know anything about the maintenance history? Most air/fuel/ignition related issues will throw a code. If this were mine, I'd start with the basics; pull the air cleaner assy, inspect the filter and clean the MAF (mass air flow unit). Inspect the intake boots, especially the little bellows/elbow that connects the lower boot to the ICV (idle control valve).

Thanks for your reply!

No light lights up... you mean the check engine light is not on? That's correct. I was expecting some light to turn up just before engine dies.

I took it to a local mechanic last week. He didn't see any fault code. He suspected camshaft sensor malfunction but since there is no fault code he couldn't assure me that changing it will fix it or not.

Cam position sensors almost always throw a code; I suspect your problem is elsewhere.

As mentioned, I'd inspect and clean a bunch of the intake tract (see comments above; also clean the ICV with carb cleaner). Could also be a bad/worn DISA. At that mileage, it's almost certainly shot. The DISA is the small rectangular box hanging off the side of the intake manifold. It has a flap in it that routes the intake charge based on throttle position. The bell crank on the flap wears out.

Hello Scott - Thanks for your suggestions. I have dropped off my X5 to the mechanic with your suggestions. By the way I noticed this morning that engine RPM was a bit erratic for first few minutes. It was fluctuating between 500 and 1000. Once it stabilized X5 just ran fine. I probably didn't notice before because I didn't wait for that long in the car. I expected RPM to stay at higher speed when engine is still cold especially nowadays as temperature is around 45 degrees in the morning.

BMW X5 Engine dies at the stop light

I had a similar problem of random stalling on my '03 3.0i, 146k miles, no codes thrown, a few months ago. Changed fuel filter, added injector cleaner and did other trouble shooting but it would still happen. Then one day I shut car off and it would not start. AAA came and jumped it but it would not stay running. Turned out the alternator failed, no battery light on dash! After having car towed to my mechanic, replaced alternator and stalling problem went away.

My E53 did it last night at a stop sign, no warning just shut off. No codes either. It did it twice today but started right back up. The one thing I noticed was the MPH meter on decel would act funny. Instead of sweeping back towards the left it would bounce back and forth. Mine has a 115K on it. Any help would be great

It hasn't done it since, but yesterday it threw a trans safe mode. Highway driving was fine but in town it shifts hard. Going to get it check in the morning and see if the battery and alternator are good as well.

I had the same problem too. It would stall at a stop sign, I tried cleaning the ice but ended up replacing it. Now that issue is fixed, it sometimes stalls when coming to a stop or the worst was when I was turning left in traffic.

Mein Auto: 04 x5 3.0d sport
Have 04 x5 3.0d-has had similar issues but on highway runs mainly.Only1 code when engine stopped(Fuel system injector...)didnt have time to read as was at 110k & looking to get off road.Restarted ok & no code.For remainder of 600k trip had surge problems off & on.Changed filter & problem seemed to go away-then has re appeared but random times.Old filter was 12mths old -cut open for inspection but no deposits.Have new pump on way & will consider relays also(behind dash & under bonnet).230k &no issues with excessive fuel use-have run injector cleaner.Last 7500k mixed town/highway has returned 28.7MPG-ANY THOUGHTS??

Running staggerd offset 19 s & thinking of a pair of rear wheels for the front(285/45/19 tyres on the large wheels.)has anyone tried this.Would be same F/R combo.
Any input appreciated.
Thanks
