S-Tronic gearbox buzzing

[ErikM]

Hi
I am new in these forums and also a fresh Audi owner.

I have bought myself an A4 140kW 2.0TFSI 2015 (the very early B9) with automatic gearbox and 75000km on the clock. Just recently I noticed that there is a buzzing sound whenever I switch from or to drive (D). I managed to record it and have shared it in Google drive in following link. .

Is it normal to make such sound? I know that gearbox was serviced at Audi at around 55000km, but only 4L oil was used, so it for sure was not a dynamic S-Tronic oil change/service.

Should I be worried?

Also had this happen once, maybe these are related:
One cold morning I had the following situation: I unlocked my car and somehow car thought it was on neutral "Shift to P otherwise vehicle can roll away. Doors do not lock if lever is not in P." A moment later when ignition was turned on I think: Yellow warning sign and "Vehicle may roll away! P cannot be selected. Please apply parking brake". And a moment later "Gearbox malfunction! Please stop the vehicle and select P". So I turned vehicle off, switched to P, turned ignition off and on and voila all started working again. It was around -2C outside and it hasn't happened since, even though several -2C mornings have been since then.

any similar experiences to share with me and what should I do next?

Erik

None of this is normal behaviour of an Stronic gearbox as far as I know, get it checked by either a gearbox specialist or main dealer. In either case they would need to pull codes I imagine first to see what errors come up.

Thanks for reply. I am kind of hoping that those error mesaages would come up once more. Every day since then, I have been recording when I enter the car in the morning, so they can't say that I am making this stuff up

Small bump for this topic. Has anyone else ever experienced one (or both) of those symtpoms that I described? Would like to find out what I need to prepare myself for, before going to get gearbox checked.
