Audi A4 b9 gearbox warning

[emir_soko]

Hello, i had an oil change in gearbox two months ago and from that time occasionally I got a warning when I unlock my car on dashboard “p cannot be selected vehicle may roll away apply brake” sometimes it automaticly goes into p, other times I have to press it and sometimes it wont select P until i start driving a bit. It doesnt happen all the time itnis completely random and warning display from the moment i unlock car. Gear changes are smooth and nice no problem there. Any info would be nice. I scanned the car with obd eleven and it gave me p280500 error code. Here is also a screenshot
Thanks

Hello! Unfortunately, I did not find any solutions. The same problem after the oil change happened to me too. After a couple of months, the fault just stopped showing. Gearbox works perfectly.
