I'm doing some maintenance on the car after picking it up recently.
Is it worth getting the automatic gearbox fluid changed?

The cars on 160000m and doesn't seem to have any gearbox issues.
I don't know the cars history so unsure if it's ever been changed.

Yeah understood.

I'll be getting a mechanic to do it, but wondered if an oil change at this mileage could cause issues?

Had my x5 5 speed auto box done at a good bmw indi with 164k on it with no problems.
Also the e90 done but that is a 6 speed box and cost over twice what the 5 speed cost.

if your gonna keep the car for ever till it dies then id do it...but your car is 15 years old and worth pennies now,,so its a toss up really...im sure yours has the 6 speed box..dont quote me on that though...
