Thank you for the feedback. I looked my CCV pipes and it seems that they have been replaced 5 years ago(two separate pipes now, the production year is 2011). The pipes looked fine, but the connections did feel a bit loose, but it can be because of the how the connection is sealing with only one o-ring. I will try the electrical tape soon.

If someone has INPA available during the morning cold start in freezing temperatures, I would still be very interested in the valve lift numbers. Just to eliminate any problems with valvetronic control module.
