Hello, for 2 days my Sprinter has been making a strange noise after the gas take away or tossing gas pedals. The noise comes only with operating warm engine. I did a short video where it is quite good to hear, starting from minute 1:25 starts with the noise I thought he was the turbo, therefore also this view at the video. The service consultant of Mercedes thinks that it is definitely not normal, have an appointment for tomorrow 1.10.15, there is the workshop master again in the house.
