Problems with a BMW dealer?

What a shock!!
'52' mean it's a 2002 car, doesn't it? I know in my case, at the end of my tether, I took a print off of these threads - including photos - to my solicitor who basically confronted the dealer and said, look, if there's no problem, why did BMW change the suspension design? That pretty much did the trick.
If your dealer is like the dealer I used to deal with, you'd have to drag them backwards through horse manure before they start to even recognise you have a problem. With a sheaf of paper from mini owners all around the globe claiming a similar problem, plus documented fixes listed here also, the very least the dealer would have to do is acknowledge that there is an issue here and you're not making it up (mine said, "it's in your head!!!"). It's always a rotten call - it's your will versus the dealer's but you are ABSOLUTELY not the first to have suffered this problem.

At this stage I would also be doing a little research into your rights under the warranty to have what is essentially a known problem fixed.
Finally, some dealers are far more customer-focused than others. Depending on where you are, I know this site did a dealer survey a while back also. Perhaps you'd get a more sympathetic hearing from another dealer who might smell the sweet lucre of a trade in somewhere down the line?
Keep me posted - but certainly start printing off some of these threads and kicking some dealer-ass!!!
Hope this helps a little
