Yes, i watched that and found it very interesting.
After all the facts were presented - only happening on same size of rims fitted with run flat tyres, cracks appearing in same places, and only affecting rear wheels when it was quite rightly pointed out that if potholes were the cause, then front wheels would be much more likely to be affected....it is absolutely scandalous of BMW to insist it is drivers fault and not cover it by warranty.
Good on the guy who got an independant report done, then started legal action....BMW werent long in backing down, because they knew they would lose.
