I have a 2004 Citroen Xsara Picasso 1.6 Hdi. I have been advised to change gearbox oil. Can anyone tell me where the gearbox drain and fill plugs are located?

you WILL have a box fault before any recommended oil change interval. If you must change it then early units had a large drain plug with smaller level tube bung/ Later units had square plug then remove level tube inside (allen)to drain. Filler plug is under the inner selector cable. Use genuine fluid.
