No worries Paul, better get your gold membership and advertise it m8
A couple of things i should add after receiving a few questions
the window motor that has packed up is the drivers side rear , not the front one !
it does have rear parking sensors (as can be seen in the pictures
)
the e39 540 is a 4.4 litre not a 4.0 litre like the ones fitted in the e34
these engines do NOT use oil like the m5 (it never uses a drop between servicing)
cheers
