So I've got this 2016 A6 with the 7-speed S tronic and honestly, it's been such a joy to drive up until about a month ago when things started feeling a bit off. What's happening is that when I'm cruising at low speeds, like around 40 to 60 km/h in stop and go traffic around the industrial area, I feel this slight shudder or vibration that seems to come from the drivetrain. It's not violent or anything that would alarm a passenger, but I notice it because I know my car and it just doesn't feel as buttery smooth as it used to. I've already taken it to two different garages and got completely opposite opinions which is driving me crazy. One guy told me it's probably the dual mass flywheel starting to wear out and quoted me a crazy amount, while the other said it could just be a software glitch and I should do a transmission adaptation reset. The problem is, neither of them seemed super confident and I got the impression they were just guessing based on what they've seen on other cars, not necessarily Audis specifically. I know these S tronic gearboxes are incredibly sensitive to the correct fluid level and the proper service procedure, and if you don't follow the exact specifications you can end up causing more harm than good. A friend of mine who used to have an S5 told me that the mechatronics unit is a common failure point on these and that it's crucial to find a workshop that really understands the intricacies of the Audi dual clutch system because it's completely different from a traditional automatic. I've been doing my research and I'm leaning toward finding a specialist who deals with these on a daily basis rather than a general transmission shop that works on everything from Toyota to BMW. I actually found a website that explains the common issues with these gearboxes in detail and it really opened my eyes to how complex these repairs can be. They mentioned that a proper diagnostic involves checking the clutch adaptation values, the fluid pressure, and the solenoid functionality, which requires specialized equipment that most normal garages don't have. What I really want to know from anyone here is whether you've experienced something similar with your Audi and what the actual fix ended up being. Was it a simple mechatronics repair, a clutch replacement, or did you have to go for a full rebuild? Also, how did you find the workshop you trusted with your car? I'm based in Sharjah and I've heard that there are some good specialists in Industrial Area 10, but I'm honestly overwhelmed by the number of choices and I don't want to pick the wrong one based on just a few online reviews. I've been driving my wife's car for the past week because I'm paranoid about making the issue worse, but I really need to get this sorted out soon since I travel to Dubai daily for work and I can't keep borrowing her car forever. If anyone has had a positive experience with a shop that genuinely knows what they're doing with these Audi transmissions, please share your story because I could really use some guidance right now. I'm also curious about whether it's worth getting a used mechatronics unit or if I should just bite the bullet and get everything rebuilt properly because I plan on keeping this car for at least a couple more years. The thought of spending a fortune on this repair is stressful, but at the same time, I know that ignoring it will only lead to a bigger bill down the road. I've seen a lot of people mention that finding a place that offers Premium Audi gearbox repair in Industrial Area 10 Sharjah is the way to go, but I'd rather hear from actual owners who have been through the process and can tell me what to expect in terms of cost, time, and overall experience. Any insights you guys have would be massively appreciated because I'm tired of stressing over this and I just want my car to feel right again.
