Hello, next week my fat guy arrives in the rental workshop on the lift. An oil change is on. I want to do it myself, as with my previous vehicles. I already got the oil, the oil filter and a new sealing ring for the oil drain screw. Before I start – a few more questions: When lifting on the lift – do not forget the lifting mode for the air suspension. Where are the exact lifting points? In the VWVORTEX there is a nice guide, but sorry the W12 seems to be a little different at the lifting points than the V6 TDI. I would not like to clamp the air ducts of the chassis. Remove undersea protection under the engine – is the cracked, screwed or plugged? Is there a service flap in the undersea protection? How do I get the undersea protection? (I first spent half an hour with my Mercedes. Should have informed me better at that time.) Mercedes, which like the P. has a changeable filter insert, you had to be careful not to forget a small seal at the lower end and properly attach it. Is there such an important little thing at the Phaeton too?) Otherwise the same program as always: Drain screw on – drain out – close again with a new sealing ring – new oil filter – new oil – Finished. Forget something else, or consider? Thank you
