Hello to everyone and all the best for the coming year!!
My daughter is having issues with her car, it started with the battery loosing power, I told her to have boyfriend take the battery out and charge it over night, the car started, and then I found out it was going flat again and her boyfriend was having to jump start the car for her several times to get her going. The idea was to replace the battery (waiting for her to find receipt as battery was only 15 months old) she told me that one day she had no indicators and this was for a couple of days, and then that the head lights came on after putting the key in ignition. After delving further the boyfriend had been jump staring the car at the battery in the boot and not under the hood in the engine bay. He then tried to jump start the car rolling down a slight gradient and he did get the car running but said the engine was idling rough and the wipers were now coming on. I had a larger battery and put that in and got same results no start and lights came on, with just a click what seemed to come from the starter. Then there was lights on the ignition. I took both battery`s home and charged them up. They were both reading fully charged. Went back to the connected original battery in boot and placed the other batter to the terminals under the hood, left it for 10 mins and tried to start nothing. so I then connected the jump leads from my car to daughters, before this I swapped the BMW 1 3 5 SERIES E60 E87 E90 F10 F30 6901469 black relay behind the glove box. When put the key in ignition I had lights on the dash again. tried to start the car after about 10 mins and I heard a slight move on the starter but that is all, gave up in the end until I can find some info on what the issue could be.
Grateful for any imput
