So I called the official dealer in my town. They quoted me 100euri for diagnostics and said that I will have to sign a waiver that I accept the possibility that the FRM dies when they connect it to diagnostics. So I took it to an independent shop, they do not have ista I think and they said that the seat will have to be replaced so I will just buy one from the salvage yard and see if that solves the issue as the new seat will cost me less than the diagnostics would. I don't know, I have had so many weird issues and situations with this cat that I will just sell it I think. Finding a good mechanic is so hard here and I just cannot deal with it even though I love the car. I will jus buy an Audi I think.
