Should I ignore the engine emission warning on my high mileage diesel Volkswagen?

I'm driving a 2005 Volkswagen Touran 2.0 DSG automatic diesel. It has done 138,000 miles. Is there anything I should get done? It drives well, however, the engine emission warning has lit up on the display. The dealer I bought it from says not to worry but what do you advise I do?
You've done well. But as long as the DSG fluid and filter have been replaced every 3 years, the DSG 'should' be okay. Lots of potential problems with the engine. But the emissions warning light is probably because the DPF is full of ash, or it could be because the EGR is getting choked.
