2005–2012
Mk2 (1P/PQ35)
Illustration — use it to know where to look.
Location
Driver's side, under the dashboard below the main light switch cluster. A plastic panel (approx. A5-sized) pulls off or unclips to reveal the OBD port. The port is not visible until the panel is removed — locksmiths unfamiliar with SEAT often miss it. Not in the driver's footwell floor area; it is at dashboard level, left of the steering column, behind the light switch panel.
