E60 530D Tourings

[si_xsi]

Hi All,

My brother is looking at these, likely to be 2005-2008 in year, with 75k miles plus. He needs a touring due to all the family gear and his job. He has had BMWs before but all were E30s, my favourite being a 325i touring.

Anyway, I would appreciate it if owners could shed any light on the key things to look out for, I've heard swirl flaps...no idea what they are or what they do, but allegedly they break. Are there any must haves? I think the engine gained more power in 2006 ish. I'm sure they have ben discussed on here a lot, so any useful links would also be good because pistonheads search is a little limited...

Thanks

Simon
