The cylinder bore must not be measured when the cylinder block is mounted on the Engine and Transmission Holder:VAS 6095A because the measurements may be incorrect.

Special tools and workshop equipment required

CAUTION:

Risk of damaging the cylinder bore surface through incorrect handling.

- Never handle the cylinder bore with service equipment (drilling, honing, grinding).
