Hello. Those 1.3 have problems with water imerge inside.like a lot of Opels. It is still good weather outside. Your glow plug is not newded now. But in winter, you will have a bad starting. If you cannot succeed in selling it. So, open that ecu, wash it good and if there is not something to resolder, get another ecu.
Also, take a brake spray and wash all that connectors where the BCM stands, check out those relays and fuses. It is placed on the drivers' side, under the wipers , in the engine bay.
