Opened up the hood and found leaky coolant all over the alternator and turbos. Seems like this is a known issue. I have a third party warranty so I called them immediately and they said take it in. Just got the call from BMW that the coolant lines need to be replaced... Surprise surprise... I got a 540 for a loaner, wouldn't leave my car without a loaner, need to get to work. My warranty is paying for it to be replaced, so I'm getting what sounds like brand new coolant lines and hoses and clamps. I have the option to return the car, but all of my car friends are encouraging me to keep the car and just let them replace the coolant lines. They say once that gets replaced the rest of the N63TU2 is pretty reliable....

Thoughts?
Being that that’s a big known issue I’d keep the car. It’s being replaced and you likely won’t have an issue again with that. Glad your warranty is paying out already.
