Going to make the turn from the road leading into the plant and I go to down shift from third into second. I hit the gas to rev match and nothing happens. At the same time, my steering becomes really tough and the car seems like it doesn’t want to turn. I then look down and the check engine light is staring me in the face. Then I realize that’s because the engine has decided it no longer needed to be on any more. Because the clutch is already in, I hit the start stop button and it fires right back up.
This isn’t the first time that it’s decided that it hasn’t wanted to be on anymore. Usually it’s under deceleration in second gear or sitting idling at a light. Done it a handful of times and has had no problem restarting each time. Don’t know what’s wrong, doesn’t appear to be throwing any codes; it was at the dealer for recalls on Wednesday and they would have told me if anything was wrong, because they want to charge me to repair it, they mentioned some oil seepage. So I have no idea. The strange thing is I put 26000 miles on the car in a year with basically no issues. Now that my drive to work is only 15 minutes, it seems to be acting up.
If I wasn’t so upside down on it, I would be thinking about getting something else. Maybe not, I just don’t feel like spending a lot of money chasing a gremlin.

idle air motor/stepper motor problem perhaps?
possibly only as a complete throttle body
just my 2c

The plot thickens in today’s installment of: “Is an M3 Actually More Reliable Than a 3-series?”

Both possible causes of the issue.

Apart from the throttle position actuators, the M3 has been very reliable. That said, It’s taken me almost 4 years to put 29k on the M3, I’ve done the same to 3 in 15 months.

Oh boy. I guess BMW got rid of the idle air control valve on the n52. Instead the valvetronic system is used for maintaining idle.

I know that feel. No idea why mine is on either.

Mine was on cause the engine was off, it’s not actually throwing a code.

Good news is the part appears to only be $200. Looks like I might have to get it and see if that’s the case.

That’s what your “I guess I’ll take a flyer and replace that part and see” level is as a BMW owner? Man I’m never gonna own a BMW

I’d unplug the maf and see if it still does it. Maybe it just needs a cleaning.

I had some studdering/missing at seemingly random times. Never threw a code. Never completely died though. Cleaned MAF and VANOS solenoids and ran some Techron, but no change. Had recently changed plugs already. Decided to change coils as both PM and possibly fix the miss. Worked great. New OEM coils had a much different design with heat shielding integrated into the coil. Pricey to troubleshoot unless it’s time anyway.
