Hi
the two are not related, disconnecting the battery usualy cures the epb fault, also a low battery will cause it aswell
the servive indicator just needs reseting, instructions below
also some info on how to manually operate the epb below

Hi David, and welcome to the club.
Having a similar s type to yours I have had a look inside the engine compartment and decided that it it needs an expert. If is has been serviced regularly and good garage will note things like that.
My car had a new engine while in Jaguar ownership at 21k miles so it will no need a cambelt change until next year.
Regards,
Peter.
