Last time I tried with my DS708, It seemed worthless to me, like I was limited to just a few OE battery specific cold cranking amp choices and wanted me to enter some Bullsh@t numeric code found only on original equipment battery . I called BMW dealer  to get a battery code number off the BMW battery that had the closest CCA rating to the aftermarket one I put in. The Parts guy was of no help.

  Everytime I get a German car a simple job that should take 20 minutes on an Asian or USA car takes 3 times longer because they engineer in Tuetonic Bullsh@t to make most people have the jobs done at the dealer level. Gets me mad and want to adjust the car's speed limiter all the way down to 80 mph so the @ssholes that buy these cars "Retrofit their Tuetonic Turds with a Toyotas" LMAO
