So I***8217;m having issues with my e65 draining my battery. Originally took the vehicle for this same problem three weeks back, indie shop said it was power module was not going to sleep so was replaced. Ended up replacing battery (not OEM) and was working fine for two weeks then my abs/transmission failsafe mode came on and really limited my vehicle power and left me stranded. Put an original OEM battery but wasn***8217;t registered, a lot of ppl say that doesn***8217;t matter?Had to jump start vehicle and took me about 5miles and died again. Replaced the abs after doing my research and still nothing!!!! Please help!!
