Yesterday my E300 (188K mi.) was being "test driven" by a guy looking to buy it. Long story short, the car is now in "limp home mode" and was driven in it for 20+ miles. I've looked but haven't found how to get it out of or reset the limp home mode. The car had to be jumped to get it home. The guy tells me it was stuck in second (LHM) before the jump. I was wondering (hoping) that the jump had something to do with the LHM? How do I get it out so I can see if the tranny is OK or damaged? What causes LHM? There are no check engine lights. Am really hoping this is something simple. Low fluid? bad trans controller (or trans fluid getting into it)? I wasn't in the car when it initiated the LHM, so I don't have many details. How do I test? TIA
