Hi,I have a Peugeot 207 a 57 reg, my car has gone crazy, wipers & lights keep coming on when the car is switched off, all sorts of alerts keep flashing on the computer, Stop no oil, battery flashes, airbag warnings, economic mode...oil & water levels are fine so it's not that & battery is also good, I have disconnected my battery for tonight as I don't want a flat one in the morning. Has anybody got any ideas what is wrong with it. Thanks in advance
