Emission Control System & Glow plug system lights on

[Sonita]

Hi, I have a 2004 Audi A4 1.9tdi. Yesterday in normal driving conditions, the emission control system light came on and the glow plug system light started flashing. The car was still driving fine and no overheating or funny noises. Any suggestions as to what the problem might be and how to fix it without having to take it in? I read about similar problems and someone said their DPF filter got blocked and that this now needs to be cleaned or "regenerated" Does my car have a DPF filter? What else could the problem be?

Welcome to ASN.
You need to get a diagnostic done as it could be many things & any suggestions would be pure guesswork.

As above, only a diagnostic will narrow it down as there are many sensors associated with the system but 2004 1.9 are all pre-DPF era.
