Oil replace instructions

Here are ELSA instructions about oil and filter change.
Inspecting engine oil level, PDF
Drain off or suction off engine oil, PDF
Replace engine oil filter, PDF

It's clearly noted - Always replace oil drain plug.

I've sent an e-mail to info@skoda-info.cz regarding oil overdose and drain plug replacement.
They forwarded it to their colleagues who will contact me as soon as possible. Never replied of course.

Regarding root cause of plug replacement it can be contact corrosion of oil pan, plug and water in between.
Or maybe just washer thing.

UPDATE (2013-04-07)
Docs updated.

Note that since 06.2011 (manufacture date) capacity for CBZB changed.
I've checked in ETKA - oil pan is the same, so something changed in engine. Cylinder block is different and probably something else.
