Phaeton 1.15% is leased: new VW warranty extension?!

Hello community! My current Phaeton from the 1% leasing unfortunately goes back to VW, but… It’s probably beginning of February the new one! So, now my question: The “Lifetime guarantee extension” is probably no longer available in its previous form. This has been replaced by a new warranty extension from VW?! Now it’s the case that the warranty extension can’t be paid once by me,but you are counted on the leasing rate on top of it. To me the dealer has told 35,84€ monthly. On the website is spoken of individually calculated rate/ or one-time payment. Is the sum of 35,84€ thus correctly stated?! Bzw. is it really not possible to pay the rate once for the 1,15% action?! What does it have on itself? I thank you in advance for the answers! many greetings Thomas
