Peugeot Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Mark and I will try help you with this.
You will need to connect a suitable scan tool to read what fault code has been stored. Because the engine is running fine I would suggest that after the code is recorded it then be cleared. If it returns after a road test then it will require further investigation as to the cause and find the solution. If it doesn't return then just forget about it.
