A tricky one for me, the rattle sounds like some sort of a loose trim that makes noise when starting cold at around 1500 rpm. Its very clearly heard from inside of the car as compared to the outside. From inside, it seems to come from under or behind glove compartment area. It goes away when the engine gets warm. Its sounds very plasticy if you know what I mean but what I don't understand is that if its a plastic trim that's rubbing against something at certain rpm range, why does it go away after certain time of engine running.

I have taken the car to couple of garages and they are unable to locate it. Like I said, the noise doesn't sound mechanical at all but goes away after the engine has been running for about 20 to 30 minutes.

Has anyone experienced anything similar? Any help would be appreciated.

      BMW 318i boot locked can’t get into

      Update: I checked my battery and it charged in 5 minutes, so I don't have to find another alternator. All seems to be OK except for the plastic "L"s with a short rubber hose that bypass the HV/AC solenoid. Those get clogged after @ 150,000-190,000 miles (if distilled water wasn't used) and cause air pockets that try to burst radiators. I have a few more brass "L"s, so now I can throw the plastic ones away. I have to be careful I don't fog the windows though, without heat or cool.

      105C thermostat replacement

      You are absolutely right. The strange thing is that when I put the chassis number on the realoem it shows that the temp sensor is not applicable on my vehicle. I will physically check for a sensor. In the meantime, do you think that the removal of the MAP activated thermostat will effect the temp gauge on the dial instrument item 6? I am tempted to add a dummy resistor , 11.5ohms - 13watts , to simulate the MAP thermostat. Your thoughts?

      SLIPPING CLUTCH

      Morning Andrew I normally disconnect the Neg lead only, some folks disconnect both a few even say disconnect both and touch them together. Goes without saying both sensor plugs need to be checked and a squirt of contact cleaner applied never hurts 😅 Dave

      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.
