Hi All, Thank you for the answers. Since my post and your replies, I've started reaching out to transmission specialists, and it's been interesting, to say the least. None of them wanted to do an adaptation, and since I'm afraid to do it myself, it hasn't been done. Only one mechanic was committed enough to take the car for a test drive. He mentioned that I might have a dual-mass flywheel issue, but at 30 km/h, he couldn't reproduce the symptoms. However, based on what I described, he suspects a clutch issue and suggested a full transmission rebuild. I contacted another guy who seems like a great professional and has a very good reputation in Hungary. He told me that they don't really do diagnostics nowadays, but he suggested flashing the factory software onto both the ECU and TCU, just in case the car has a previous aftermarket tune. Other workshops never answered my emails, so I guess I will need to call them. For now, I've put my car up for sale until September, and then we will see. What are your thoughts on this? Should I go down the software update route or the transmission rebuild route? I definitely love this car, but if I sell it, I would like to buy one with fewer miles and a much better trim (for example, the B&O system, because I can't stand this 8-speaker setup).
