Engine Malfunction time to time.
I was driving on the freeway light throttle about 30-40 mph and got Engine Malfunction, Power reduced. Came home turned the car off, message disappeared, went to my indy shop, the car was showing no codes. Been coming on an off for a few days now both in street driving and freeway but always when im at city speed.
Carista is showing code 2c57 Car doesn't drive any different and I can't feel anything. Boost builds as normal and it drives perfectly fine. Anyone know what the issue could be? Did some research and checked older threads but couldn't find concrete solution. Thanks! |

This is based out my experience with a 2013 650i wherein I experienced 3 engine malfunctions in the year and a half I owned it. Car was a BMW CPO with 43K miles. Each time, the car would vibrate and misfire but the malfunction code would go away and car seemed to run ok. Each time I brought it to the dealership for warranty repairs, they ended up replacing a combination of ignition coils, spark plugs, HPFP, and various vacuum lines.

For me it was the vacuum lines on top of the motor. Just disintegrated over time, they crack, and you can't see the crack. I replaced one, but still getting the engine malfunction, then run rough, then next startup it's fine. Just replace those plastic lines on top of the engine. It says misfire cylinder 6 for me, but there's nothing wrong with cylinder 6 as I replaced coils, but even the dealer couldn't figure that one out, lol.

Tough to say really. If you said it feels like it's running normally and building boost as it should then you'll likely be OK but have that AAA card or other tow coverage handy just in case.

Drove it 100 miles today, and it was all fine, so going to hope my luck stays with me and it's all good.

I've been chasing reduced power warnings on and off for like 3yrs, replaced all the CCV lines and like 3/4 of the vacuum lines and it still comes on. It's annoying as shit while trying to race someone or it just happening randomly (I've even learned to shift into Neutral, cycle the engine off and back on, then back into Drive while still moving) but it hasn't stopped me from making three Bimmerfest trips from Seattle to Hollywood to Vegas and back so I'd say you're fine...but keep chasing it because it's only going to get worse.

Little update, after about 150 miles of not getting it, it pop up on the freeway on ramp.
This time I felt no boost coming in from the small scroll in the turbo. So from cruising RPM up to about 3-4k it felt dead, after that boost picked up. Took it to my indy, but by the time I got there the light disappeared and no codes were stored. Told me it could be attributed to the car getting hot lately??? Ill keep an eye out on it tomorrow during my road trip. Hopefully this thread will help anyone else having the same problem. |

You guys won't believe it. Its been 200 miles from the time the code last showed up. As my mechanic suggested it could have been bad gas and it makes sense. I usually fill up at shell or costco, but before that filled up at sinclair, and after that the code started showing up. If anything changes I will update the thread, otherwise don't fill up at untrusted locations.

I was driving on the freeway a few days ago and all of a sudden there was a message that came on saying "Transmission Malfunction" Drive with caution or to the side of roads or something to that nature. But the car it was like slipped into neutral in the middle of the freeway. So I braked and stopped the car, threw on my hazards, shut the car down and then restarted the car and it was like nothing happened. I went on my marry way. I got to my destination turned off the car for an hour or so, got back into leave, started the car put into drive and it wouldn't move forward. It was like the front door was a door ajar and it wouldn't let you move. But it left go in reverse. No message this time. So again, I shut car off, turned it back on and drove on. No issues. Three passes, I turn on the car and try to reverse this time, its like it got stuck, then turned off the car and turned it back on and no issues... What could this be?
I should also say that the day before all this started I was driving on the freeway and AWD/4x4 malfunction came on as well. Shut the car off, turned it back on and I haven't seen it again since then. The car was served at Seattle BMW about three weeks ago. They said the car great. Had an oil change. No issues... Baffled.

Also Id suggest you make your own thread. This is for engine malfunction which is different from Transmission. That way you will get more helpful answers |
