## NHTSA's summary

On 4.0l bi\-turbo FSI engines, the pipe on the impeller side of the bank 2 turbocharger looks discolored when compared to the pipe on the bank 1 turbocharger. The crankcase breather is only connected to the bank 2 turbocharger inlet. Blow\-by gases from the crankcase breather discolor the pipe. This is a normal condition.
