Hello, I have the next problem with my C70 T5. During the ride, the warning light for “gas cleaning system” flashed several times and then went out again. One day after that, the lance went on permanently and at the same time I hear a squeaking / grinding noise when I’m driving slowly along house walls or guardrail. The noise stops as soon as I give gas. I was able to locate the noise in the standing car. It comes to the right of the engine from the deep. It sounds like grinding or tyres. When the engine is switched off, the noise runs out slowly. So it has to be a rotating part, which makes this noise and brings the warning lamp to light up at the same time. However, I haven’t noticed any performance problems yet. I have thought of the turbocharger under consideration. A blower or other part of it wasn’t immediately the exhaust lamp to light up. Do you have any idea what it might be? I’ll definitely make an appointment with the friendly and wait for the Volvo Pro Garantihilfe…
