2004 BMW 330ci 6 speed manual - 3.0L inline 6 cyl. Intermittent problem - idle becomes erratic and car stalls. This has happened approx 6-8 times over 8 months/5000 miles. Normally happens on warm days and at a stop light/stop sign. It once happened in the middle of a turn which caused me to lose power steering. Dealer has seen the car 3+ times and updated idle control valve, and engine software but problem persists. It is very intermittent and doesn't throw any computer fault codes.

BMW 330I exhibits frequent erratic idle when stopped, as well as engine stalling. Erratic idle is in the form of engine speed drops below 400-500 RPM. Stalling sometimes occurs as a result of these idle speed drops. This is a common issue among recent 330 model BMW's, and apparently there is no known solution at this time.

Car suddenly lost power at low, intermidiate and high speed. Car will shake violently, sputtered, then become undrivable. Check engine light came on. Brought in to dealer and was told car has misfired. Dealer proceeded to repair problem by reprogramming computer chip per manufacturer's service bulletin. Was told the car is fixed and safe to drive. 200 miles and on the freeway at high speed, the problem resurfaced. Was towwed back to the dealer nad was told that the air flow sensor and soemthing else was the issue. Replaces both parts. Repair engineer thinks that there is a 99% likelyhood that the problem is fixed. I am not so sure since that said the same thing last time. Since the car is not on the list, it is a BMW 530I sedan.
