   Talked to the service guy at Mercedes today.  He's got me thinking that   
   it just might be the idling that has caused this error.  This is the   
   first diesel I've had that uses DEF and has all that newfangled emission   
   stuff.  He claims idling is not good on modern diesels because it can   
   foul up the DPF (diesel particulate filter).  I guess these things do a   
   regeneration cycle as needed, but it is done only at a fully warmed up   
   engine and while actually driving.  I guess it gets hot as hell.   
      
   So, I guess when I get a chance I'll pull it out and take it for a spin   
   and see if the damn lights go off.  Would be nice if that's all it is.   
      
   Also gotta figure out a way to get a battery tender out there.
