An electronic problem
The problem with the indicator lights is that you are by no means certain that you have a problem.

Do not climb too much in the towers, it could damage the car. We advise you to drive at 3000 rpm. The temperature of the engine block will therefore roast the stored dirt, and therefore purify your FAP. If such a procedure does not work well, you will need to replace it.
