The check engine light on my 2002 C230 came on and after taking it to the dealer, the service rep tells me that the sensor code indicates oil in the wiring harness and that parts and labor will total around $1200. He also stated that a mechanics bulletin to all dealers indicated this problem has occurred on this model before. My question is how often, and is it possible that this should be covered under a recall? I also have a 2003 ML series and have been very happy with both vehicle until now.
Thanks
