Good afternoon one and all, W211 E220 Estate Avantgarde Just replaced a new rear suspension air compressor (AIRMATIC), replaced relay for new, checked fuse at side of dash.....still no power going to compressor. I am lead to believe there is a pre fuse (number 74) I think which is 40amp. I am also lead to believe it is a complete barsteward to get to as it is in drivers footwell under the carpet. Is this correct and is there a cheats way of getting to it as it looks like accelerator pedal needs to be removed to get carpet far enough back !!! Any help is much appreciated.....Ta !
