Coolant Leak

[drose224]

Experienced a coolantleak in my 2016 750i xdrive at 37,000 miles. Still under factory warranty. Dealer did a system pressure check. Found coolant leaking lines for turbocharger leaking. Fix: Replaced all turbocharger coolant lines with both brackets. Refill and bleed system. Just a heads up that you may want to get a system pressure check.

So the turbos which run very hot uses coolant hoses to cool the turbo bearings the hoses are a combination of steel pip and rubber hose, yes rubber hoses basically sitting around the hot turbo of course they sta leaking after a while I don't know why they just didn't make the whole pipe steel
