Does anyone know a possibility of why I'd get be getting a drivetrain malfunction. I put the car in sport and everything and I'm using maybe 40% throttle and it says the malfunction and pulls back on power. Anyone had this problem?

I just went through this myself, check coils, spark plugs, guibo and rear diff mount. Mine turned out to be guibo was damaged and rear diff mount was bad. Check to see if idle vibrations are higher then normal.

The funny thing is sometimes it'll idle lower than normal. Sometimes it'll idle at 500rpm and other it's at 800rpm. It also sometimes has a little hesitation in starting the car. It'll start but it takes a little

Lesson for anyone who owns or buys ANY N63 engine based car, invest in a decent OBD code reader. These engines are notorious and there are tons of threads/forum entries/FB groups/Youtube videos on all the issues ppl have seen. And this is beyond the CCP and the Bang Settlement which enabled some ppl to get new/refurb'ed engines.

DTM could mean a lot of different things, and that is why you should try to pull the codes first.

That's true, I'll get a code scanner as soon as it comes up again because I can force it to come up if I push the car. I haven't put the pedal to the floor yet because it'll come up. But when I cut the car off and turn it back on it's gone

I'd still get that reader asap for around $100 (or get ISTA setup) and check those faults. It could be something simple that is slowly going that causes additional items to go.

For example, running a dying fuel pump could result in damaged injectors, something that costs a couple hundred in parts could turn to a couple thousands in parts (this is just an example to show the severity).

9 times out of 10 it's a simple fix, if you own a N63 then you should have a reader and deep pockets, believe me as I would know but I am also pushing the limits. Your issue could be as simple as a loose intake pipe or bad plug, running it hard or not over time it will slowly break down other components. Just my two cents

You could also try Carly app on your phone, it works great for me

I had a couple drivetrain malfunctions, one was failing high pressure fuel pump and the other was a faulty spark plug. Terrifying though since it seemed like the transmission just dropped out while merging on the highway. In reality its just "limp mode" to limit power and protect the engine.

550bye, I see you've done quite a bit to your 550. I Imagine some issues along the way, but any significant problems you experienced? I have 2013 550 with just Dinan tune and high flow DPs. I'm curious about upgrading turbos, but have no idea how tuning would work in order to make use of them. Also don't want to blow my engine and don't know what else is needed to mitigate associated problems.

As long as you manage your maintenance and resolve any issues that pop up along the way you will be okay. I definitely think you will need a flash to get everything out of the upgraded turbos though, you should hit up Percell with Heatsync, he has turbos and can set you up with a nice tune for your setup specifically plus he's an awesome help.
