Peugeot 206 Malfunction lamp

When I was washing my car today, I attached water to the engine as well. It just came to the engine to get the dust in the black parts.

teacher, you made a mistake at first, our vehicles are not washed without proper insulation.

Thank you for the comment, I opened the engine door of my teacher, I left it towards the sun, the vehicle has become a result of water leakage, now the malfunction lamp went out.
