Just bought my first BMW for about 20 years, a 2009 520SE business edition estate.
I need to fit a towbar as we tow a caravan, so was after some advice, mainly..
Any recommendations as to what sort, what make, whether to go for a vehicle specific electric kit (one which plugs straight into the wiring loom, if they do such a thing?), do I need a bypass relay, etc.
Any advise gratefully received.
