Cümleten Selamun Aleyküm; I have 307CC 2.0 16V 180hp (2004) for 6 years, it stopped, it started to give all the malfunctions one after the other. .. We could not find the master of this car .. Most of the services do not want to get infected, I spent a serious amount by saying that the infected change it and change it so far .. Isn't there a "solid peugeot professor" in Istanbul? The malfunctions given now are; Intermittent failure. Engine coolant temperature sensor signal plus short circuit or open circuit Intermittent malfunction. Air pump relay control open circuit Intermittent malfunction. Air injection malfunction in the exhaust Remote spurious error. The coolant temperature sensor (with VAN network outputs) received unit is wrong Outdoor temperature sensor. The unit purchased is wrong What has been done; The crank sensor has been changed to the exhaust end including the catalyst after the manifold .. I do not know if the name is the same, but the idle sensor has changed The temperature sensor has changed The thermostat has changed The knock sensor has changed Spark plugs changed. Throat was cleaned. All electrical wiring was dismantled and cables were checked. Gasoline pump was checked. Injection control was done. Brain control was made .. Many sensors that I could not think of, oxygen etc. Like .. And yes, we still haven't reached a conclusion .. The vehicle works like a rocket in the morning, if it is a bit hot in the weather and asphalt and if I enter the traffic, it stalls and stops .. I wait for 15 minutes to cool down, it continues as if nothing has happened. I wait for it to cool down and continue on the road .. Water does not mix with the oil, oil does not mix with the water, there is no heat problem, there is no swelling or hardening in the cooling system pipes, there is no blowing in the engine, there is no oil reduction, but there is no problem in the smoke or engine block, a very extreme reduction There is no problem either, it is considered normal because I tighten the engine too much. Does anyone have any master suggestions or ideas? I will order a fish by the throat to a friend who will help me solve the problem .. Someone said to sell the car, he has the name "Firdevs" why should I sell him my friend, I love him .. Thanks in advance ..
