New to me....1999 300D turbodiesel....I've had about 6 mos., 175Kmiles on the odo.

Today, after starting, the glow plug light came back on after the engine was started, ....then the check engine light also came on.

I'm a decent DIY mechanic, worked a fair amount of VW Vanagons and Subaru engines, but this car and diesels, in general, are all new to me. Not sure where to start.

Need help w/ making diagnosis and deciding if this is a fix I can manage or will I have to take it to a shop.

Suggestions and tips please.
