KW – Sensor

Moin,moin for the first time.. My Omega is hungry..er “frisst” KW sensors. Now the 4th this year at a total of about 25,000 km. He got the last one before THREE months and didn’t even hold 10,000 km.. Can it be that the things are not good or does the wear on sensors perhaps have another reason?? The last one was out of the accessories because I needed the car urgently and it had to go quickly… The car now has 177,000 on the clock, is always nice warm driven and hardly scared. The candles are also clean… It regulates at approx.4,000 1/min. and the MKL lights up briefly… Error code is…as always..the 19th. Has anyone ever had similar problems?? I thank you and wish you a nice Christmas. mfg Horst
