Just buy your plastic sump plug from VW Group
dealership, or buy a trusted aftermarket brand.
They are so easy to fit correctly - once you have changed one you will find this out, don't worry about it - I even bought the correct tool to remove/fit them, didn't cost much. From memory, I bought 2 the first time "just in case" - if buying online, doing that makes sense to save on P&P.
Edit:- plus, if you are the type of person that is just pumping the engine oil out, replacing the oil filter then refilling the engine with new oil - you have only carried out a basic oil and filter change, you will not have been able to check the underside of the car over - and that needs doing, maybe boring and not something that you want to chat to your mates about, but needs doing periodically, as well as checking over many other areas of the car - like brakes and tyres including the spare (if applicable). I tried using an oil pump once, a Pela one, got really bored waiting for the job to get done even with warm oil, then lots more time to clean the Pela out - much easier and quicker dropping the lot out quickly through the sump plug, decanting into "holding container" then cleaning your "oil catcher" and funnel up. I knew beforehand that I was wrong to use an extractor - but I felt the need to buy one.
Getting the oil out of things like boat engines and gearboxes where a dedicated lift pump is not fitted or available, is more the place for these Pela oil extractors.
