806 gearbox oil level?

I posted this question recently but the answer was not correct for my
vehicle.. It was suggested the gearbox oil on an 806 turbo diesel (year
1997 ) is checked by identifying the larger bolt head on a ring of bolts
on the gearbox extension cover accessible from the left hand wheel arch,
where the bolt is the oil level plug. But my gearbox has a ring of bolts
all the same size and believe the original suggestion must be for an earlier
model.. I know my old 205 used that method .So, if anyone can advise me the
correct method I would be very thankful. Thanks in advance. KF.

In that case, I think the level/filler plug is on the final drive,
just over halfway up, pointing to the rear of the vehicle. You will
need a 21mm spanner to undo it. Not very easy to get to, unless you
jack up the front, but that will of course give a false reading! Best
checked on a ramp.<!-- ~MESSAGE_AFTER~ -->
