Apparently with the twin turbos of the V8 are mounted on the top of the engine, with the oxygen sensors heat shield, there is still not enough cooling. Engines are overheating thus resulting in engine fires!!! UGH 
I am so bummed because I am first up for a 2009  but now I am worried--BMW is scrambling to find a redesign, I doubt it will be a major engine redesign (i.e. relocation of the TTs). BTW, there is s difference in design with the TTV6--these turbos are lower and near the rear of the engine with better air flow.
Has anyone else heard about this problem? I see some folks are having their 2008 V8 "delayed" so I wonder if this is the real cause. |
Here is a partial fix.These stainless steel vents found on the hood of all the preproduction,tester X6's.I've wondered why on many occasions that these vents did not make it to production vehicles.Especially on a TT engine that we all know runs hotter than a normally aspirated engine.On the TTV8...these vents would be right above the TT's in the vee of the engine.Seems like a nobrainer to me.
