If it's the engine warning light that's illuminated then it doesn't need immediate attention but do have it looked at.

It will probably be either the well-known EGR problem (for which there is a fix that Volvo should pay for) or a dirty O2 sensor which needs a clean (a 20 minute job for the dealer).
