Hi all

first post

i'm on here for my mother who has a 2002 540i, now don't get me wrong i drive an Astra and can pull that engine apart all day but this is not as Astra lol. Her car battery is dis-charging and when i tried to turn it over the starter was just ticking, battery was reading 11.2 v so low, jumped the car and it started fine, alternator was showing 13.6-8 v, my Astra shows 14.6 and my dad's Supra 14.7, am I correct in assuming that this is a little low?

is there another fault that this car suffer from?

Any help would be appreciated

Cheers all Stranton

The 540 has ALOT of leccys on it which can drain the battery, plus if the battery is not in the best of condition then this will throw the alternator readings down.

New battery and your faithfull E39 will return

      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.

      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
