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.

 

Technical Background

The crankcase breather is only connected to the bank 2 turbocharger inlet. Blow-by gases from the crankcase breather discolor the pipe (Figure 1). This is a normal condition.

 

Service

  1. If necessary, explain to the customer that this is a normal condition.
  2. Do not replace any parts due to this condition.
