What are they doing to get this 'fixed'?
I've had my '13 for a year and it's happened to me a total of 3 times. Not too common, but still annoying when it happens.
Just got it back today. They replaced the Radiator Fan with an updated version and flashed new software onto the DME

Have had 3 limp modes in the last 2-3 months. Car is at the dealer getting the aux fan replaced right now. They also cracked a hose while replacing it so now that part is also getting replaced.

Based on a lot of the responses, the 2013 models are having all these limp issues. Any 2014 or 2015 models having the issue?

LIMP Mode Aux Fan Replacement

Any help would be appreciated on current F30 335i engine issues....

So I was getting limp mode, no power from 2k-3k rpms, air conditioner blowing warm, aux fan running super loud, engine oil temp gauge pegged at far left of gauge. After shutting off the engine, I would restart and the car ran perfectly fine with the exception of the check engine light staying on. This would happen maybe once every two or three weeks, then it progressively got worse. It would happen every week, then it started happening every day. I recently replaced the auxiliary fan, and ran the check engine codes. Following codes were viewed and cleared:

Thermostat Jammed Open
Auxiliary Fan not running at full capacity
Fuel micro leak
Mass Air Flow Sensor short circuit

I cleared all codes, and have put about 100 miles on it since the auxiliary fan swap. Luckily, no check engine light as of yet, but it went into limp mode again this morning and it has started to throw a "drivetrain malfunction" warning. But the car continues to run perfectly fine. After the limp mode this morning, car ran fine except the air conditioner would start to blow warm at idle, then blow cold under load and normal driving. I am starting to get really frustrated. The next fix will be the thermostat since I received the "thermostat jammed open" code. Anyone experience these problems? Any suggestions?

So my car is currently in the dealership for this issue and the SA let me know that they are replacing the fan and reprogramming the DME. Does anyone that had the MPPK installed before having the DME reprogrammed have any issues after? I'm wondering if the MPPK is something that needs to be reprogrammed into the DME? The dealership is claiming that as long as the DME is not replaced the MPPK should not be affected but I could've sworn that I saw something different in the forums but can't find it. Thanks in advance!

Same symptom had happened to me for the second time driving on the freeway. First thing my SA says is they won't be able to do anything if they can't replicate the problem.
And I have 3 days left in my factory warranty.

Thankfully I had recorded the power loss and the max fan speed outside of the car and sent those to the SA. Got an update that they ordered a new electrical fan and gonna install them tomorrow.

Will report back if the problem continues.

Thanks,

after 30k miles on my 2015 435i, no limp mode.

I probably had 10 by 30k miles when i had my 2013 335i.

Just found this thread... 2014 335i M Sport 6MT and have had 3 limp mode occurrences in the last 2 weeks. Took the car to the dealer today and waiting to hear what they say. As others have mentioned, my SA said that without any warning lights it will be tough to diagnose. Trying to time it where I can bring the car in when it goes into limp mode is a complete crap shoot since the frequency is so inconsistent. I will post back when I hear.

Have a 2013 m sport 6mt as well. 40k km. First limp mode/fan issue a few days ago. Dealer ran the codes, said the instructions were to just update the software, no new parts. Hope that was enough!
