I have just purchased a lwb (8 seater limo) W124, with the 250 diesel engine in it. I have found in the boot, there is a second battery and and a closed module with the lettering "PSW" on it, and a large red cable from the battery to the module. There are other wires too, which go under the carpet to the rear area. Does anyone know what this module does??? And why are there 2 batteries on this model?
