I am looking for a bit of advice with my Battery. I have a 2009 BMW 318D.
I am getting the yellow battery symbol flashing up on the dash when engine is turned off with keys in the ignition. I checked the battery charge via the OBC and it reads 14.5v when engine running and drops to...
ok i looked up on realoem which battery i need for my car and it gives 2 options
110AH regular battery
90AH AGM Battery
confusingly the 90AH is the more expensive battery ,
when i rang the dealer he asked me what i had in the car that there was 2 choices so whats the difference :confused:
