Hello together, I am the Salih new here and have no experience with forums yet, but I’m struggling. Need your support urgently. So in advance it’s my Renault Fluence Dynamique 2.0 16V 14CVT L30G with 140 hp / engine type M4R 751 / 190TKM. In addition, it has an LPG system from Prins. It doesn’t start in cold condition. Starter spins a few seconds then comes to check the error message injection. About an OBD I have the following messages: P0340(29) cams Len position sensor circuit Too few impulses B122C(64) CAN message from the control unit motor control unit missing internal fault of the impact sensor 3 on the passenger side (Passenger Side Crash Sensor #3 Internal Fault) P1525(F3) Air bypass valve (Air Bypass Valve) OT sensor (I think the crankshaft sensor) camshaft sensor suction tube pressure sensor (air pressure sensor) have been replaced as last. spark plugs about 2 years ago as well as cleaning the throttle valve. Even if I use the gas Turn off the system, so only petrol is running it does the same problem. As soon as it is warm it starts up again immediately. After a few hours no more or just try after several. Besides, the speed varies in idle mode, when the engine is warm the variation becomes less (700 to 800) About the evaluation with OBD I could see that the intake air and cooling water temperature changes (so temperature rises slowly). But I have the fear that this will be an infinite story for them. Because as mentioned above they have already changed some parts. Has someone an idea what it may be about. Greetings Salih
