I don't know if there are differences in the set up between the two models, in reality I wouldn't think there is much. I have alignment checked annually at service and the last time I noticed the print out said E70 mine is E53 but checking settings against the previous year there was 1/2 deg on camber at the rear difference. Annual service will be due again next month and I have no noticeably odd tyre wear in 11k so seems OK.
Lets hope this fixes or at worst reduces your wear to a manageable level, thanks for the update it's useful information for others looking for ideas to cure similar issues
