206 Speed sensor fluctuation

I do not have much information on this subject, I could not find any information that would be useful on the internet. After the pressure pad and ten sets have changed completely, the speed hand fluctuates after it has accelerated a bit, and even more when it passes through the light coccus. There is a long thing waving like a swing. I have noticed that the holes are more common. What could be the problem? the koray.tur 2015-03-29 10:57:23

The speed sensor is located on the transmission and is a very gentle part. My guess is that they didn't fit the sensor properly. Go to the place that made the change and explain the situation. It will be done in a short time.

Thank you, I will go tomorrow
