A5 Parking ?

Hi guys

Wonder if you have any suggestions.,

I have a 20 foot X  10 parking area with 2 paving stone runways  to the side of my home great  

But to this side is a BIG SILVER BIRCH tree with a Conservation order on it.

It is dripping lots of sap on the A5 CVT and the tree can't be altered. 

In  front of my home leading to a garage is another drive maybe 15 feet

I went to park the A5 but as I pull on the the drive before I get to the garage door the

rear wheels on on the road level at the Dropped Curb,  Front wheels are on the drive

So the A5 thinks its on a hill and won't just Creep.  At that point I am maybe 2 -3 feet off the Garage door.

I start to to try a bit right pedal but i feel nerrvious i am  just going to go into the garage door  a BIT FAST  rather than creep.

Can i fiddle on the Brake button its  a bit of a pain yet.

I have parked normal Auro car on this drive but they  did not know the were on a hill.

Any ideas  is it just right foot action ?
