Check the brake pedal switch for the ABS and ESP problem, you might need to replace it. For the tail light problem check where the bulb plugs in and make sure the bulb has good contact, it is a common issue. Sometimes the plastic housing melts a little causing the bulb to not make contact.

I had the same problem with the rear right bulb. Tapping on the side cured the problem, but as it was happening all the time, I changed the bulb. No more problem. Now its starting on the left rear side This happens to be the first time I didn't change the two bulbs at the same time. I always do this as a preventive measure to avoid later hassles.

some lightbulbs give out less power than they should, so it gives faulty information to your ECU, maybe it's just a simple problem?
try changing all the bulbs you had replaced recently
