DGT/Trafico published a new form to be used for renewals of EU licences for Spanish, both as a result of their announced ´2 year resident´ protocol, as for renewals of naturally expiring EU licences.
The info from the DGT website re ´renovacion de permisos comunitarios´ can be found here:
The actual form can be downloaded with the link to the right of the page.
Please note that you´ll need to make a first appointment with Trafico to present your original licence, ID and copies. They´ll take the copies and will verify the authenticity of the licence with the foreign authorities. Once they have received notice back, they will contact you and you´ll be required to make a second appointment, only then will you need to hand in your original licence, the medical certificate etc. and you´ll be issued with a temporary Spanish driving certificate, valid to drive in Spain until your new Spanish permit arrives. So don´t get your medical for your first appointment, as it might run out by the time you´re asked back for your second appointment.
UPDATE May 2016: according to recent member´s experience in Granada Trafico they check for your entitlement online – don´t forget to bring your National Insurance number! – , you have to sign a form to authorise them to do so (same procedure as car rental companies since abolishment of the counterpart). So no need for 2 appointments there anymore. Hoping all other Trafico offices will follow.
There is a special ´cita previa´ for EU renewals. Info HERE.
For further info re the issue of validity of EU licences in Spain, I gladly refer to the article on the website.
