In as far as our local LR representative seems
that to does not exist, their ordering system is down since August
and does not accept spare parts order,
I would like to ask you if exists complete availability of spare parts in your country.

No problem here in Switzerland.

Most parts are in stock with the distributor and the few that are not are normally received from UK within 10 working days if not sooner. However if the factory's spare parts supply logistics system is also OOS then that's a different matter with unknown lead times.

I had no problem when i bought the door handles and mud flaps resently

BUT there was a delay in getting a rear diff of about 14 days

Try contacting the forum sponsors with what you require

if the forum sponsors can't post it abroad, try contacting the parts manager at Yeovil Land Rover, sponsors of Disco3 as he might be able to help you also, (goes my the name of the large one) Former Mod/Member, with the most post & Chicken George Arch nemesis
