Hello. I have a question whether without the driver's pin code which I intend to buy I am able to assign it to the car op-comem. Generally, the car has a broken driver because after warming there is no control for one injector and the car goes on 3 cylinders. I wonder about overdraft memory from the old driver to the new (used) which would probably settle the matter of ecu exchange as soon as possible. Only a question to the experts, what memory sits there. Driver delphi delco fahf D04004. 12230740.Auto to astra H 1.6 twinport
