I am leaning towards replacement now, as I do not want it to cause any other issues with the car.

Its essentially imperative that you replace the battery with a decent AGM 70ah or 80ah battery and make sure its registered / coded as required..
With 30+ ECUs on board the E89..many of which don't know how to /expect to cope with a poor battery all sorts of both temporary and permanent faults can manifest themselves..hope that's clear enough?
