Hello, I am looking at the forum and on google and nowhere to find information where in Corsa C ctdi 2004. is the main system relay located? Does anyone know where to look for him? The Corsa did not start at all (in the evening I normally returned home, did not start in the morning). She was shooting but did not fire. Checked fuses - ok, exhausted and tested fuel pump - about Corsa started firing but only cold. The heat does not start anymore. P1625 error after connecting to computer. First, the suspicion fell on the shaft position sensor, but after this error it can be this relay?
