Drivetrain Malfunction
So i was driving my F12 this morning since it was a beautiful day and was on the highway. After the engine had warmed up I decided to do a quick pull from 60-(a little more than 60?) and after I was done, I got the Drivetrain Malfunction warning. Power was cut on the car so I pulled over at a gas station, turned it off and then back on.
I got it going once again and again got the Drivetrain Malfunction warning I couldn't tell if it threw a code immediately because my CEL is already on due to catless downpipes(only mod on the car). When I got to work, I plugged up my OBD2 reader and the only code the car was throwing was for the Catless downpipes. I'm a little confused because there was no Code whatsoever and the Drivetrtain Malfunction warning goes away after a bit but performance is still cut to the car. Anyone have any experience with this? The car has just under 24k miles now |

I feel your pain. Just had same problem with a brand new motor swap recently. Try changing out your coils and plugs, if you can do it yourself it is relatively cheap. If that doesn't work, you might wanna take it to the dealer to check your fuel injectors, there is an extended 100k/10 year warranty on them for your car.

Welcome to the rabbit hole my friend. There are several threads on hear about trouble shooting DTM. Look around and read, its worth the time I promise you. Plugs, coils, Fuel injectors has usually been the sequenced I've followed. If you are computer literate at all it may be good to invest in ISTAD and an Enet cable. Very easy to trouble shoot for fairly cheap. Good luck man.

Next time connect with your scanner before cycling the ignition off. Sometimes the fault code is not being stored. The ECU needs to see the fault occur X amount of times for the ECU to record it. |

Most likely coils and plugs, if that doesn't work than it's your injectors. If you're running the car with no tune the car is going to naturally run richer.
