[Vwdiesel] *CEL light on middle of road trip*

[Rolf Pechukas]

hi all
2001 Golf TDi
middle of a several hr drive, CEL just came on
checked the oil and coolant, bout all I can do on the road, both OK
how worried should I be? how immediately should I have someone pull codes?

this car still recovering from alternator job where shop left off the hard pipe from the turbo to the intake
smelly exhaust since pipe replaced, and I saw yesterday in the rear view mirror smoke of some kind under load (moderate acceleration)
never noticed smelly exhaust or smoke of any kind before the alt mishap

2¢ please? thanks,
