Volkswagen Golf Mk7.5 (2017-2020) Questions & Answers

I have recently bought a VW golf 2018 TSI. I was wondering if leaving on the park lights for over an hour or even overnight would considerably drain the battery?

wondering if anyone else has had oil leak issues? I bought a brand new 110TDi wagon late last year took in for a service and the noticed an oil leak from the main seal, took it back to get that fixed and while they had the transmission out they noticed another oil leak this time from the gear box seal....both covered under warranty however they couldn't get a new seal for the gear box so have to replace the whole gearbox instead.
This is not my first golf and i have never had an issue before but am now concerned at what else my be wrong???
