This is how big an Alarm für Cobra 11: die Autobahnpolizei nerd I am.
   Three years ago (April 7, 2016), we were introduced to Daniel Roesner as Paul Renner in ‘Cobra, übernehmen Sie’. There is a flashback scene dated April 7, 1996 when Paul and Semir meet for the first time, with Paul as a child.

   There are a few problems with the scene.
   If it was April 1996, then it would have been around the events of ‘Tod bei Tempo 100’, and Semir looked quite different:

   His goatee only begins appearing in episode 33 (production order), ‘Ein Leopard läuft Amok’ (October 1, 1998), and the BMW 3er with the registration NE-DR 8231 made its first appearance the episode before, ‘Die letzte Chance’ (which was actually shown later, on October 8, 1998).
   Also in ‘Cobra, übernehmen Sie’, Semir is on the radio to Andrea, when Andrea was not working for PASt in 1996. She made her first appearance in ‘Rache ist süß’ (November 18, 1997).
   I can understand star ErdoÄŸan Atalay being reluctant to shave his goatee for the flashback, but it would have thrilled fans if he called to base for Regina and not Andrea.
