Hi. It is a Seat Cordoba 1.9 hdi 2001 and all normal. I give contact, turn on the preheater light, a few seconds, start and it is marching perfectly. The problem is that after a minute the light begins to flash as if it were the turn signal light and so it goes on until the trip is over and I turn off the engine. I have knowledge of mechanics but little electricity. Maybe someone can guide me. From ya. many thanks
