Car rolls forward slightly in reverse

[hod05]

Hello my 2010 A207 with 250cdi Engine and 5 speed auto rolls forward on my drive whilst in reverse. Today was the first time I noticed it. The car will reverse up the slope fine with throttle but with foot off the accelerator the car will roll slowly forwards.

To be fair the drive is quite steep but is this normal? The car never rolls backwards on any slope whilst in D.

112k miles fluid changed about 2 years possibly 3 years ago but I only do around 5k miles per year.

Could this be a torque converter problem appearing or normal?

Normal.

Normal. There is a sprag in D that stops it rolling back, but not in R
