A211317 2034999-2017-12-05. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. 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.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
