Reparing 95 c280 Mass Airflow Sensor....
 

I need to change the Mass Airflow Sensor on my 95 c280. I was told it cost a lot. Ive found onr on Ebay for $80, and it says the listing price is $500. Can you guys tell me if this is the correct thing. I mean, if this is the sameMass Air Flow Sensor. Also, is there any way to try and repair the sensor instead of replacing it?
