BROKEN CAR??????????
 

Hello everyone
I have Swapped my Subaru for another car and think ive broken it!!!!
But i know from when i had my STI that there are some clever people in this forum so HELPPPPPPPPPPPPPPPPP

I have just fitted a TANDEM TUNING BOX to my PEUGEOT 307 110 HDI
When i drove the car the engine warning light came on and the power cut out. I have adjusted the Tuning unit so the vehicle can be driven hard without the engine cutting out but the engine warning light is still on and the display is reading an ANTI POLLUTION warning, Will this go out in a couple of hours and the warning light go out ?? Or have i knackered my car??
THANKS IN ADVANCE. CHRIS
