Wilson, as your new chassis is post 2014 you're not affected.
+1 on Hugo's comment, none of the dealers seem to know anything yet.
Agreed for the chassis but the pedal box is a different issue. Mine has the laser cut pedals. I have emailed Dave Cartwright to ask if this might have been looked at when they did the total rebuild.

Good point Wilson, I was just thinking of the chassis.
I agree with your later post that MMC should just replace the pedel boxes with the new spec.
From the earlier thread it looks as if the original M3W cut pedels were only fitted up until Nov 2012 so there can't be that many out in the field. The cost to inspect properly and take remedial action would soon build up and a straight swap programme has to be safer and cheaper. Particualary as swapping the pedal box is something that can be easily done by any decent mechanic.
Checking the chassis is a whole different kettle of fish as more cars potentially impacted as they are looking at up to the end of 2013.
