So I've got a 2017 A6 that just crossed 60,000 kilometers and I took it in for a routine service last week, and the service advisor mentioned that it's about time to think about changing the transmission fluid. Now I'll be honest, I've never really thought about gearbox fluid before, I always assumed it was something that just lasted the life of the car, but apparently Audi recommends a change at certain intervals depending on the transmission type. The quote they gave me was a bit of a shock honestly, we're talking about a pretty significant amount for what I thought was just some fluid and a filter, and I'm wondering if this is actually necessary or if they're just trying to squeeze more money out of me. I've been doing some reading online and the opinions seem really divided, some people say it's absolutely critical and will extend the life of your transmission, while others claim they've driven over 150,000 kilometers without ever changing it and had no issues whatsoever. I came across a specialist that offers Certified Audi Transmission Fluid Service and they explained that the fluid degrades over time, especially with the heat we get here in Dubai, and that contaminants build up which can lead to premature wear if left too long. That made some sense to me, but I'm still not entirely convinced it's worth the expense right now when the car is shifting perfectly and I've had zero issues. I guess I'm just trying to figure out whether this is one of those preventative maintenance things that'll save me a huge headache later, or if it's just a nice upsell that I can safely skip. Has anyone here actually had a transmission failure that they think was caused by old fluid? Or on the flip side, has anyone done the service and noticed a real improvement in shift quality? I'd really appreciate hearing some real experiences because I'm genuinely torn on whether to go ahead with it or wait another year. Cheers.
