have a problem with my 320i 2009. The orange engine warning light is flashing and the car vibrates. The vibration is worse when the air con is switched on. Can any body help?

Hi Richard

Welcome to the Forum

As you have a CHECK ENGINE light flashing you have a problem that needs attention NOW if you are not capable of diagnosing it yourself you need a Garage or Mechanic

The vibration could be a misfire, or a loose pulley or tensioner turning on the AC increases the load on the engine so will not help.

Check the timing pulley. My e36 had this issue where the pulley had perished and moved forward and back, stopping the sensor from detecting the timing, causing a misfire.   Also worth checking the aircon pump bearings.

      SLIPPING CLUTCH

      Hi Dave, I fitted one of the sensors on the rear but it has made no effect as the light is still there, I will fit the other sensor tomorrow and see how it goes then. You mention the disconnect the battery, is there any pattern to this ? is it both leads or just the negative lead? cheers Paneuro.

      105C thermostat replacement

      Not sure what engine your running but there should be a Temp sensor in the Hose from the Rad to the water pump then there should be a Temp sensor in the housing for the Thermostat Both are shown in realoem for the 3.5 V8 I thought the V8 was the only one with dual use sensor on the Thermostat housing but stand to be corrected Dave

      105C thermostat replacement

      I have checked realoem and it gives me no temperature sensor option , which is strange. Also what I did was to remove the map thermostat and disconnected the resistance heating that is inside the thermostat and replace it with a 88C from an x5. Nothing else has been changed. The strange thing is that it run like that for 3 weeks in August. When I start the car last week the temperature dial was going to max before dropping to normal value. And that happened only when cold. When warm the dial was showing the right temp. I also saw that the map for the thermostat was engaged when the car was running cold which made me think that there may be a connection between the thermostat dial and the map thermostat not being connected.
