Replacing battery
Need some quick info on this as the '03 E46 Touring's battery apparently just gave up the ghost after 5 1/2 years.
Does anybody know if a certain amount of voltage has to be maintained on the electrical system during a battery change? I didn't see anything in the maintenance manual and I'd hate to dork up something like the OBC, which would probably require a trip to the dealer for re-programming. |
