520D Deisel consumption (2001)
I have changed the vibration damper, and the Tensioner. Right after changing them, I start hear like squeak on the start, and the consumption of the diesel went up. Specially at pickup, the car consumes too much diesel, it goes up to 20 l/ 100 , where it used to be around 10. I also smells unburned diesel when idle. The dealer thought it is the PRESSURE CONVERTER and the Fuel hose to be changed !! does it make sense ?
