You all must have been asked this questions a hundred times before. If you have I apologise for asking again. My Audi A6 2.7Tdi 2007 has had the glow-pug light flashing on the dash and going into limp mode usually once a week over the past 3 weeks. However, today it did it 4 times on the way home. Any help or advice would be gratefully received.

Today's VCDS printout for the technicians out there and many thanks:
