I have a corsa D 09 automatic, I have had intermittent battery drain problem. It’s fine for a week then battery goes flat over night, had 3 garages look at it, battery and alternator fine as fitted new when last time had problem. Didn’t resolve the issue still kept waking up to dead battery. Car will boost back to life or jump start, garages said their must be parasitic drain on battery, so had auto electrician look at, but on the day he came, the car worked fine. He still did some checks and said everything was fine, he noticed lights took while to kick in, but not sure what he meant as I wasn’t ere and wife felt with him, he said all leads from battery okay and maybe it could be to do with the gear box and to dead lock the car every time. Which we been doing and worked fine for 10 days no problems starting every day, wife came to start car today late in afternoon and nothing dead again, car jumped okay and works when started no dull lights etc, starts everytime when key is turned off and on, can anyone shed any light if they have had this problem and how they fixed it as it’s driving me insane and I just want put a match to it at this point. The following problems have happened with the car in past. Battery died few years ago and bcm came uncoded to key immobilise was on and key wouldn’t take it off, so had that sorted at garage. We fitted a new starter at time as thought it could been that. New battery fitted by garage, bcm remapped. Few years later battery and handbrake light came on whilst driving it. Pulled over turned car on and off light extinguished and not happened again. When selecting drive etc the solinod thing wouldn’t disengage even after try resoldering wire. So cable tied solinod thing open with cable ties. Works fine selecting gears ever since and not had this problem. This year this problem mentioned above keeps popping up randomly. It has head unit we fitted since we had car, 5 years ago now. The battery light has started to stay on now when we jump the car or boost it, but if we have fault code cleared it goes off and when it’s on it causes no problems with starting g car unless it’s left over night. Anyone had this problem or can help would be appreciated thanks for reading

I hope this will help some folk in the future
garage has had my car now for last 4 days with car not showing any battery drain problems until today, faulty part found to be the ecu not the bcm as suggested on few forums I read over the internet. We could of had this replaced at garage but lost faith in this car now and we going part ex this one, so cannot advise if this fully fixes the problem as we not going go ahead with the repair now but hopefully someone might get some use from the this
