Hello dear Elchgemeinde, Will buy a c70 t5 automatic at 121.000km Bj2000, where the Mkl and the Ets lights up.Error reading resulted in turbocharger, overpressure sensor input low.The speed is stable when running empty and when driving slowly everything was okay.If you delete the error, the lights stay out.After switching off and on again, the lights light up again after a few seconds at the same time.What do you think it can be?
