2002 passat 2.8L v-6 engine light is solid yellow

2002 passat 2.8L v-6 engine light is solid yellow–I am out of town now or I would have the codes checked-- what happened is about two days after driving out of town the engine check light came on-- I notice that the odometer just turned 60,000-- could this have anything to do with the engine light coming on? I ask because in the service schedule at 60k it says that the computer diagnostics should be run at the 60k check up – also on the first day after I saw the engine light the keyless entry stopped working but now after sitting a couple of days that is working again – any ideas on that or is it all coincidence? also can I drive it home (about 700 miles)?
