Yes, there was a recall in the USA but not for European cars. (Second class citizens?)
I think you will find that there has been arcing at the junction between the stop lights and the printed circuit, leading to an intermittent connection that will eventually fail completely. I had exactly the same problem, and the answer was simple:
1. Remove the rear light assembly (3 nuts hold it on - fairly easy to access via the small panel in the wing/ by removing the first aid kit). Remember to unplug the multi-plug!
2. remove the stop light holder and you should see the extent of the problem.
3. For slight corrosion/arcing rubbing with an eraser or using fine sandpaper could be sufficient
4. In my case there was complete breakdown of the printed circuit, so I bridged the gap with solder and buffed it down. Smear the new joint with electrostatic grease - important!
5. Check the other bulbs (unlikely to be affected, but if so, repeat the process)
6. Reassemble the rear light clusters.
I put this off as long as I could, because I foresaw major difficulties in doing the repair. In the event it took less that 30 minutes to do both sides. Best of luck!
