Scirocco has w5w holders like sidelight bulbs unlike the golf which has festoonsThe link is on the first page steve with the discount code They don't flag any errors. You must ensure they are fitted the correct way, as LEDs only work one way round, so before you screw the holrs back up, pop the bulbs in and check they work!

Pop the unit out and check the wiring is pukka
