C230 Mass Air Flow Sensor problem

[MEZHH]

Hi. I need help again. I have a C230 1998 (W202). We had a problem with MAF sensor and changed it. After 10 days it broke down again. I thought it was defective and changed again, it also broke down after a few days. We changed it again, it also broke down after 2 days. I don't know what to do. What could cause to break down the MAF sensor?

Oil vapour depositing on the very thin wires in the MAF.
Next time it happens, use a spray to clean it and test on the car.
