Just booked my sport into Yeovil for second service and asked them about the battery's and was told they should be changed every service! Anyone else been told this?
Also it's not part of service and are charged extra! Not booked till beginning of March so a bit of time to check this out. I know they will not be expensive but just checking.
Also asked about any discount on service and offered 10% for just asking. Well it's better than nothing.  MY11 Autobiography supercharged. Santorini Black. Monaco interior. Rear screens. Privacy.
Gone MY08 Supercharged HST. Java black. Ivory premium interior. Rear screens. Privacy. Missed a lot.
Gone MY04 Discovery V8 Petrol ES Premium. Awesome.

Not heard about them needing replacing every service, perhaps it something they do but don't shout out about

Had to do one of mine at the weekend, car is 14 months old I I got the low smart key warning on one of the keys.
Was a 1 minute job to stick in another CR2032 battery which you can get them for pennies on a well know auction site.  ON THE WAY: BMW F21 M140i
