drivetrain malfunction

savagee_m2 · 05-24-2017, 04:16 PM

I have seen this message appear a few times before when I push the car (usually in sport +), the simple fix is to pull over, and restart the car (or drive moderately for a while) and boom... you got your beast back with no errors.

However recently, I have been driving locally around town and it will seem fine, but I get (drivetrain malfunction) way to frequent, even in comfort mode! I do have a jb4, and my assumption would be that its faulty from the jb4, or the car needs like a new update from bmw! What do you guys think, what should I do? Anyone experience this annoyance??

Take it to the dealer and complain about your JB4 mod not working properly.

This is exactly why I have not done JB4.

Heard this same story about 5 times. "Car keeps going into limp mode when running hard."

Will this happened for JB+ or Dinan Sport Tuner?

Read it about all the piggybacks. Read all the threads around. The only real solutions I see working good are full out custom tunes. And I have not finished modding in order to do a full tune.

i'm looking into getting the dinan piggyback. If it went into limp mode, could I take it to the most local Dinan authorized workshop (which is also a BMW dealer), or take it a non-BMW authorized Dinan workshop?

Most likely both, but none will be able to do much I would belive.

I understand the limp mode is the OEM ECU going into safety for the potential boost peak increase combined with other factors (heat, bad fuel causing knock, etc). Solution is to turn off and back on from what I read but this on a track day would be annoying.

I get this message and my car is stock.

DoggieHowser · 05-27-2017, 05:49 PM

Could it be due to the engine still being cold?

Damn you BMW why no temperature gauge on pre LCI?

Go to your dealer and for an upgrade of the software... It might be the option dealing with it. Let them first read out the ECU and see what kind of failure message there is, it could also well be another problem.

I removed the jb4, and the message is way less frequent but still occurs. I might just get a custom tune

I've got the stienbauer piggy back and have had no issues. I've had it for 8 month.

I got that message on my M235I last year at the track. The consensus I read was it was because of fuel starvation. I never get it during normal road driving, even spirited. I've always assumed the M2 would be immune to this type of failure, and designed to handle more under hard driving. It must be a overall BMW thing.

If this is happening on a stock car even during normal driving I would definitely have the dealer or professional shop check it out.
