Yes, the plug is 24mm and located to the front 3/4 way up approx on the passenger side of the gearbox assuming RHD. You can see it from the engine compartment and I do it all by standing on the bumper and leaning in with a socket and wrench. Once out if it dribbles whilst the car is level then it is ok, TO TOP UP use one of those squeezy oil bottles and a tube through the oil and put in the correct Hypoid oil till it starts to dribble out then replace and gently tighten the pug. *** Job done. Take care not to put too much body pressure on the RADIATOR CAP as the neck has a tendency to break away leaving you with an expensive repair for an CHEAP oil top up.*** YOU MAY FIND ACCESS EASIER BY REMOVING THE AIR FILTERS MULTITUDE OF PIPES AND BOX.
