View Full Version : 2008 Freightliner Sprinter with Turbo noise?

I have a 2008 Freightliner sprinter 3500 chassis(2010 Leisure Travel Unity)with possible turbo type noise. Originally heard it at lower speeds and thought it was a wheel bearing but got in mountains and notice it going up hill and would stop when I let off gas. Had a authorized freightliner service center mechanic test drive and said he was hearing some turbo noise and don't worry about it till I got home. I read similar issues with 2005 & 2006 having bad turbo resonator. Also read that 2008 model resonator was redesigned and fixed (my resonator does look differant). I have 27000 on RV, started around 23000. Anyone seen this issue with the 2008+ V6?

Remove and inspect air intake hoses and boost hoses. Look for oil on the resonator.
