Hi guys, I need help in getting to the washer bottle on the M3 - it is very different form the 330 I used to have, being that it seems to be located at the front bottom of the car and via an extended hose to fill the bottle up. The problem I'm havign is that it's not producing a strong stream/no stream to the lights or windscreen - It maybe fouled as it smells a bit. Anyone have any suggestions to curing the loss? Any additives to try and disolve the particulars out?
