G12 service action updates

 I know just a another stupid t-stat,,,,but this is special,,,,it’s for the new service action on a new G12 750,,,,there are 4 new service actions at the same time. Here are the new exhaust turbo coolant hoses that will be replaced. Here are both the turbo wastegate that will be replaced,,,,,and programming the vehicle with a new software update for the new waste gates,,,,,,and the 4 th thing is a updated oil service depending on mileage. Here the t-stat which we gain access from underneath the car. Here you can see the new turbo coolant hoses are replaced with numbers on them so you can tell which hose is leaking,,,,next to them is one of the turbo waste gates. Here the over head shot of the new G12 engine lay out,,,,a better look at the turbo coolant hoses and oth turbo waste gates. Here’s good news for some of you guys,,,,BMW changed the bad design on some of the hoses,,,,the installed metal clips you lift up,,,,you can see it on the vent valve and the turbo charge pipe,,,,so no more plastic clips that always break.

    Unfortunately the coolant hoses for the old N63B44 engine were not overhauled. That means if the hose is faulty the turbos must be unmounted to install the new hoses because it comes with the metall pipe on it. 😦 Same thing with the crankcase ventilation pipes….

    Now you made me very curious 🙂 Can you please explain which special tool you are using to unbolt the colant lines on the turbo without plug out the turbo charger? Thank you very much!

    I have the same problem on my bmw G12 750Li, I asked BMW Tunisia about that update, they told me we are not aware about it, please give us the action update reference or number.

    They only have an update of the DME firmware, they dont know about the T stat, wastegates and hoses.
