Take measurements at 3 positions in both lateral - A - and longitudinal - B - directions, as illustrated.

Difference between actual and nominal diameter: not more than 0.10 mm.

NOTE:

Measuring the cylinder bores must not be done when the cylinder block is mounted on a repair stand with engine bracket VW 540 as the resulting measurements would likely be incorrect.
