Cheers for that, I did look last night on EPC which revealed 722.435

With regard to the spanner icon, this might only appear on up to date dealership EPC software, just in case you were using something older.

Still not a 100% sure on my B1 replacement although I hope it's a direct swap over. My guess is that although the last few digits changed it may have only been to signify the piston upgrades, if so adding a later piston configuration should be okay (in theory)
