AUDI A3 2.0 TDI QUATTRO ORANGE EXHAUST WARNING LIGHT... HELP

[Quigley1988]

HI ALL , I have recently purchased a audi a3 2.0 tdi Quattro 57 plate? I have sorted the boot lock fault already and now this.

an orange exhaust has appeared on the digital dash board can anyone shed any light on why this is happening as new to audi and haven't driven one before. I have read other post and no other faults have came up as of yet. I am hoping not to be out a lot of cash with xmas and that coming up so any help would be greatly appreciated

thanks
