I am new to this forum and have searched for information on whether the E300 TD has a block heater or not with no success. I am sure this is an old question, but I could not find the answer. Question #1- does it have a block heater, question #2- where is the plugin located. Thanks

 

Yes, most E300's were equipped with a block heater. Open up the tow hook cover located on the lower valance of the front bumper. Use a flashlight to look around in there and you should be able to locate it.
