Hello, my turbo at my Volvo V40 (diesel, 1.9, 116 hp, built in 2002, 245 000 km) starts to whistle at about 1700 rpm. After the sound of the sound I dismantled the connecting hose from the air filter on the turbo and it is very clear that the turbo shovels are damaged. Apparently a part is missing from a shovel (see photo). After that I controlled the whole turbo circuit (outlet air side turbo -> input charge air cooler -> output charge air cooler -> input injection) but could not detect any metallic particles. Everything clean up to a little bit of oil. The turbo can be easily rotated by hand. There is no power loss and also no black smoke from the exhaust. Some time before the noises occurred, the hose was ripped at the output of the turbo (about 10 cm long crack) and was replaced by me on the other hand still the replacement turbo can still be charged and I’m making your EInbau itself. Think, the missing pieces of the turbo shovels can be after the change of the turbo, but it can still be turbo cool?
