Hi guys I have a 54 plate blob eye and there is a dipstick behind the intercooler, I understand this is either for the diff or gearbox oil how do I go about topping it up and which is the best oil to use in the there.
sorry about the stupid questions but I haven't had it long thanks for help guys

 

Gearbox oil
You have to top it up using a funnel and the correct spec oil should be in your handbook
Though in reality they shouldnt use much if any gearbox oil on a reletively new car. Has the car had a recent service? as gearbox oil changes are every 2 years (1 year on dccd equipped cars)

cheers mate it was serviced last october and and I've only covered 4000 miles since the service just checked it and it was low an just wondered how to top it up

 

Just remove the dipstick, add funnel to pipe and pour in new transmission fluid (ensuring it is of the correct type )

I would also check for any leaks. Also to add that if the g.box oil is low the rear diff oil might be low as well. Although there is no direct oil connection between the rear diff an gearbox.

On the rear diff if looking from the back you have two square drive plugs (screwable) Use the top one to top up and the bottom one to drain.

Ignore the red box in this pic but the sqaure drive plugs in the middle of the diff are visible.
