A4 Cabriolet 2005, emmission warning light


Registered User
Hi I have a 2005 A4 TDI cabriolet. Recently serviced and other works done. Today after a run the emission warning light came on and stays on. Any suggestions would be appreciated.

Suggestion; get it scanned by vcds (or another code reader), find out the actual cause. You will at least have an idea of why this is happening.
Clear fault (if it clears) and then see if it comes back. If it does, investigate the code further!

As mentioned above, get a code reader.
