Hi, having trouble with my e320 2005. After starting it has rough idle then stops. Starts again a few times and runs quite normal when it gets warm. Got the engine light on and read the error codes:
I also try to do the same, thus one does not always know what is the cheapest to start with. Normally I just google and look for parts, tricks and hints.I start always with the easiest and cheapest.

According to this guide: https://testing-public.carmd.com/Tsb/Download/18079/7114
the tempe sensor is mounted on the MAF and is not separate item, so the complete MAF needs to be replaced. However this doesn't make sense with the error code stating it is the left side of the V6 engine. Anyways I can not see anymore components related to this either.
Coolant temperature and Long Term Fuel Trim are key factors in mixture formation during cold start and warm-up phase. Intake air temperature is used to reduce thermal stress on engine.Some here are talking about the engine coolant temp .sensor ,,and others about the MAF / intake air temp ,sensor.
Does the engine coolant temp sensor signal to the ECU influence the fuel delivery ?
