I have just had this problem with my 2012 Superb. Both Cig Lighters not working. Fuse 35 blown, replaced fuse and blew straight away. Mechanic in Skoda dealership told me its a common fault, the problem lying in the wiring between the front and rear lighter and the fix is disconnect the rear lighter. I checked both with a meter, sure enough both showing dead short to ground even though the rear has never been used. Remove the rear ashtray and its holder (Stiff pull), I just cut the wires feeding that lighter barrel and terminated them with termination block. Checked the front lighter and the fault had gone. Buttoned it all up and now have a working front Cig Lighter barrel for my sat nav and phone. Total fix 10 mins.
