Peugeot 407 - ESP/ABS system fault - elekie&a/c doctor
Crystal balls are very expensive these days .You will need to get the system tested.Alternatively ,put a sticky plaster over the light and hopefully it will self heal.
Replied on your other thread. It could be a faulty or damaged ABS sensor, but its just guessing. A good diagnostic check will tell you exactly where the fault is.
