Hello, my V70 II D5 Premium automatic year 2003, 120kw with a little over 270,000 km on the clock (quickly hit) screeches me as soon as I give gas. I was in 2 workshops, but in turn. Workshop 1 (free workshop) had thought easy play. There I was because he whistled at acceleration. The charging air cooler was replaced. In the lower area the tubes were bloated, it licked out oil. Intercooler exchanged for 645,- Euronen, car driven from the yard…nu has The next day, the hoses to the turbocharger were checked, everything was tight and solid. The hose/channel below the turbocharger was opened and you looked into the turbo. The blades were very rough. As if dirt had deposited. Air filters were checked, but was inconspicuous (last change during the inspection in January). Statement of the workshop… you can’t know anything. It was suggested by the workshop: Keep driving, do nothing as long as there was no change. Car was on the test bench. Engine has normal pressure, no faults in the memory, performance values all OK. I left 2 brown bills and small change there. After that I went to the Palatinate, left 550 km behind, no change. So I drove to the 2nd workshop, also a free, but on Volvo specialisi There, too, all hoses were tested, especially those below the turbo, especially for leaks. Everything is tight, everything is tight. You can do nothing. Continue until something changes. I also have 2 brown bills and some small change distributed there. I am now at a loss. Should I actually invest 1,5k € in a new turbo or there are still possibilities / tests that I could try before. The moose pulls as usual. The noise can only be heard under load if it is supposed to pull. If i It can be heard when the engine is cold and when the engine is warm. It sounds a bit louder to me. When I go from automatic mode to switching mode to slow down the acceleration through the engine, I hear a similar noise for a moment at high speed. I had the noise recorded during the ride and put it on the server.http://www.woelk.net/sw/1.3gphttp://www.woelk.net/sw/2.3gp Image of the defective intercoolerhttp://www.woelk .net/sw/3.jpg I am grateful for every hint.
