ILUVMILS is correct. I am told (but can't prove it) that the Temic sensor is used in MB and BMW. If you would like more info on this "Oil Quality,Level and Temperature Sensor" go to www.temic.com
. At least the web site was there about 60 days ago. You should be able to print a nice picture of the sensor. Of course this is a German company. Have a nice day.
