SL500 turn signal

Hello everybody
I have been fighting a small but annoyng problem on my SL500 that I got this summer.
Both turn signal (Left and right) are flashing too fast. (180 Hz)
The Hazard lights flash normally (90Hz)
I replaced all bulbs, check grounds, replaced the combination module that controls the turn signal.
Has anyone an idea on what to look for?

Fuses are good..
The flashing rate is good for hazzard signal, and also when I lock the car (3 flashes)

Update:
When i connect a third bulb to the turn signal circuit, the flashing rate is correct.
I think I will just add a 6 Ohm 50 Watt load resistor.......
I'm still puzzled....
