Gearbox changes from drive to sport

Anyone else noticed an issue with their auto gearbox changing itself from D to S. Occasionally I've noticed it changed to sport although I didn't change it, only happened a few times and only seems to do it from pulling away, not when im moving and already in 3rd 4th gear etc. Prob a simple explanation and could understand if in auto driving mode but it's in comfort drive mode?

I think this is a standard thing from.wvat I've seen on.otber Audi models. I think it partly depends on how much acceleration is applied from standstill.

That's good to know mate, cheers.... was hoping it was something simple and dreading it bring the start of something serious going wrong 😱🤣.

Not used to the automatic box, always had manuals. 🙄

The s tronic gearbox is one of the best out there 🙂 you could always get a diagnostic check for peace of mind 🙂

 Have recently done the rear brakes  which i bought a little handheld vag device to wind piston in, also reads codes and doesnt show any faults.... unless needs more advanced interogation? I'm gonna get the gearbox serviced soon anyway,  couple thousand mile till it hits 40k, and get the diffs oil changed while it's getting done. 

Haven't yet decided whether it's a job for me on my back, on my drivevwith Jack's and axle stands or I get it done at a garage..... called one garage who wouldn't take the gearbox on?💰💰 Their vag mechanic had recently left so they can't do it?? Or didn't want to do it.... I read the guide on here which seems straightforward enough just hope the weather's ok 😎

Preventative maintenance is always good. Especially on the s tronic box. When the oil degrades the gearbox can struggle to select gears.

Booked in to a local gearbox zf Pro specialist place to get the zf gearbox a full service, pan off and changed and also front and rear diff with the centre transfer box fluids changed....bit pricey but my drive ain't level and don't fancy risking not getting the oil level bang on. 

Cars pretty low miles and maybe early to be changing oils but i cant see what harm it will do apart from drop my bank balance..... 🤪

Prevention rather than cure.....
