Can anyone tell me where the main thermostat is located on a 335D please?
I have had a look on realoem but I am not sure what I need to remove to just have a look?
I took my car in to a BMW specialist (used him a couple of times before for red boost pipe and actuator) and I took it there to replace the main thermostat but it was done very quick without the car going onto the ramps
I supplied him with a new BMW thermostat part which I sourced myself. I asked for the old part back and he gave me it back but I was a little confused as it was bone dry and cobwebs inside it
I checked the temperature on the way back and it was still sitting on 79/80 degrees after a 10 mile journey home
Can anyone tell me where it is located so I can have a look the new one I supplied is there?
