The FTE 23 5693 tandem brake master cylinder from the standard pump in the diameter of the piston – here it has a dimension of 23.81 mm instead of 22.2 mm, which allows the brake system to work better. It fits the standard servo from the Polo 6R. It was also installed from the factory on the Polo 6R GTI MY2013.
Part number
Part number: 6R1611019B (PR: 1AT+1ZR, 1ZP)
The pump fits without any problems to the brake servo from Polo 6R. In my case, it was installed together with the servo from 1.4 CGGB: 6R1614105G and everything fits perfectly.

Additional Upgrade Options
PS. On the Polos/Ibizas RHD there is an option to install the master cylinder from the S1 , which has an even larger piston diameter – 25mm. Unfortunately it is not possible to fit it to the LHD, you would have to rework the brake lines (differences in angle and connection), so this option I immediately let go 😀
If someone is more daring (or has the steering wheel on the wrong side) then they can try fitting a master cylinder from an Audi S1:6C1611019A/6C1611019C 😉
