1) Why start a new thread? Because this thread was for OP to ask about spec and pricing regarding a car. Yes, servicing (or lack thereof) does come into it, but it doesn't need to become a technical bulletin discussion. 2) I would suggest ditching DuckDuckGo. I typed 'VW front differential service interval' into Google and the relevant VW service bulletin was result number nine. 3) I would suggest doing a bit more targeted research. If you've bought the car and not known about the existence of the front diff, then the research wasn't done very well. 4) The implied level of knowledge would be based on you having done more than twenty minutes of Googling. A simple search of 'VW front differential' would highlight the terms mentioned, such as VAQ. That being said if, as you now tell us, you don't know anything about the differential, perhaps advising members on it being 'lifetime' isn't the best port of call? Seeing as you commented on '40k miles not being terribly high', I assumed you had done your research and had information from an official source. Certainly, I wouldn't be on a public forum dispensing advice on things I didn't understand. That's how mistakes happen, and how people that rely on these forums for information end up damaging their cars. 5) I'm not upset. I've been using this forum for a while and I'm very happy with it. The reason for my annoyance is that, as above, I assumed you'd done your research on the VAQ, hence why you were giving advice and were 'under the impression' by dealers. When I read someone giving out incorrect advice and then questioning where I am getting my information from, that tends to annoy me. 6) You speak for yourself. People such as @Warrior193, @Evolution13 and I agree on many things, but also disagree frequently. That said, we all have experience on the topics we discuss - which is not the case here. When you're stating experiences that aren't correct, that's when disagreements occur. I've given you plenty of links to play with. You've given us vague ascertations from stuff you've read using DuckDuckGo. Try using Ecosia - if you're going to waste your time, you may as well plant some trees in the process. 7) I'm sorry you're dissappointed. Please feel free to look through my recent activity - you'll see that I'm very welcoming to questions and new members (myself not exactly being a seasoned veteran on here). I was welcomed warmly, and I hope that others continue to feel the same. As I said, my lack of content is due to the way you've given incorrect advice, without any backing, and then repeatedly questioned my comments. Writing everything out the way I did, if I'm honest, wasn't for you - it's for the benefit of all those that come across this thread in the future and need the correct advice. Hopefully, though, they're steered towards the correct information. I'm sorry you feel this forum isn't the place for you. I wish you all the best with the forums you are involved in.
