Flush vs drain and fill – what’s actually better for an Audi with 100k kms?

Flush vs drain and fill – what’s actually better for an Audi with 100k kms?
Right so I’ve been going back and forth on this for weeks now and I genuinely can’t make my mind up, so I’m hoping some of you with more experience can give me some proper advice. I’ve got a 2015 A7 3.0 TDI that’s just clicked over 100,000 kms and I know the transmission fluid has never been changed because I’ve got the full service history from new and it’s not on there anywhere. The car still drives really well to be honest, but I’m starting to get a bit paranoid about the longevity of the gearbox if I keep neglecting it. The thing that’s confusing me is the whole debate between doing a full flush versus just a drain and fill. I’ve spoken to three different garages and they’ve all given me different opinions, one says a flush is the only way to get all the old fluid out and do it properly, another says flushing can actually cause problems by dislodging debris and blocking the valve body, and the third says it doesn’t really matter as long as you change the filter and use the right fluid. I’ve been doing some research online and you can Check out this trusted transmission oil flush service in Abu Dhabi if you’re looking for a place that does the full flush properly, but I’m still not convinced that’s the right approach for a car with this many miles on it. I’ve read so many horror stories about people having transmission problems immediately after a flush because all the old gunk that was holding everything together got washed away. But then I also think about the fact that the torque converter holds a lot of fluid that won’t come out with a simple drain and fill, so you’re only replacing about half the fluid which seems a bit pointless. I really don’t know what to do for the best and I’m worried that whichever choice I make could end up causing problems. Has anyone here got experience with both methods on a similar mileage Audi and can tell me what actually worked for you? I’d be so grateful for some honest feedback because I’m proper stuck on this one.

I’ve been in a similar dilemma before, though not with a car—more like deciding whether to grind for rare drops in apkrab Games without a proper strategy. Just like your transmission, rushing into a full flush without research can backfire secure access , especially when old sludge might clog things up.
