Problem with guarantee

Hi, After an attempt at the VW forum I try again to find some helpful answers in the hope. I have a big problem with my golf. Since I have unfortunately no overview of my rights at all I have signed up here once, maybe someone can help me. The golf was bought about 10 months ago at a Ford dealer here very close. In addition there was a one-year used car warranty. For a long time I have had problems with switching. The gear is rather tacky and sometimes the fourth gear doesn’t really go in and out. It’s very heavy in general and always scratches a little, so no noise but you feel it doesn’t flood like that. Now I was at a VW car dealership and asked if I would like to look at this and just tell everything with the guarantee that is still running and that I’m afraid that there will be a breakdown of the gearbox 3 months after the warranty. That would be for me the purest Supergau because I urgently need my car for the work and have no money on the high edge Well the workshop master then drove a round with the golf over the yard and said that he does not notice anything special. Since my girlfriend also drives a golf I know that it feels quite different to to switch there than with mine but he said, there is nothing that can be done and I should just take it that way. Maybe you can tell me if I have a chance there It’s not really broken, but you just notice that it’s not okay (that sometimes doesn’t go right in the hall I find the worst). I didn’t want to call first because I’m worried that they’re going to get me off the phone, so I’m trying to get some information. How do you see the chances that something will be done? If I can’t find a workshop that will help me out of the way, I’m really up to it. They’d make money there, too, so I don’t understand.
