In 2005 when driving my car, the car began pulling unevenly, jerking gently on acceleration up a highway bridge and the problem persisted to the dealer for service. The ignition coils were replaced under warranty.

This problem is occurring on all E46 330 M54 engines with the zhp(performance package) there have been numerous complaints to BMW na about this issue. At 2000 - 3000 rpms the engine rattles like a coffee can full of marbles. I took my vehicle to BMW but they stated that this is perfectly normal. BMW is not willing to do anything about this issue. The issue is the dual vanos unit they put into the M54 engine is using belrin bushings and they are failing. There is a company called dr. Vanos that fixes this issue by rebuilding the oem vanos with upgraded bushings. This unit cost $500, which I am not willing to spend as I have a 100,000 mile warranty from BMW.

While stopped, engine speed would drop near or below idle. Happened after cold engine start or while warm after driving (both no-traffic and high-traffic). Twice the car actually stalled (in garage and at traffic light). Rough idle can be felt in pedals and (6-speed manual) shifter. See also ODI ids 10064475,10062056,10064439.

Engine power failure and heavily distorted windshield on a 2004 BMW 330ci. Repeated failure of engine power without warning (twice in an itersection). BMW replaced eng. Computer, then installed new software after second incident. Rough idle and surging continues and gas mileage in city dropped to 12.6-13 mpg. Additionally the windshield is heavily distorted. BMW replaced it with an equally distorted one and the fse said"all 3 series windshields are distorted, worse on the X3". it is like driving in the rain without wipers. In both cases the BMW fse has stated the " there is nothing more to be done". this is the real BMW warranty service. This lemon is unsafe to drive.

The car (2004 330I zhp) often shudders at start up with an erratic idle and continues to do so even when warm. There are no computer fault codes and no check engine light. It feels as if it is ready to stall at any given time with severe idle fluctuations of 100-200 RPM's during stops. Problem is widespread across dozens of zhp (performance package) owners as well as many 2003 and 2004 3 series car owners, particularly those with manual transmissions.

Car stalled several times at red lights. RPM dropped with no warning. Also experience rough idling when at complete stop.

I have a 6-speed manual transmission 330cic and when I put the gear into neutral at a stop the engine RPM would dip drastically and stalls several times in traffic. Periodically the engine RPM would dip so rapidly that the engine stalls from idle position. This can happen in the driveway or on a road at an 4-way light. Basically anytime the engine is at idle there is a potential for stalling. I experienced stalls in heavy traffic as well as sitting at a stop light.

While driving, the car shook violently, the engine rattled and the car lost engine power; the check engine light went on. The car became immediately un drivable. It was later determined that one of the cylinders in the car misfired and completely shut down, sending the engine into a complete unbalance.
