Hello, yesterday during normal driving error messages received: Check exhaust system, check injection, check speed pilot. The car has gone into emergency mode (some power lost). Wrench and MKL are also on. Was today at Renault. You have read out the error memory and thought that it has to do with the charging pressure!!! Can you not say this more precisely in a computer diagnosis??? The master wants to keep the car there for 2 (!) days to get the error on the ground For this “diagnosis” I have already paid 40 euros. The further 2-day diagnosis should cost another 300 euros. Without even repairing anything!!! Does anyone know if it is the charging pressure sensor or the air mass meter?
