Is it ok to replace with a higher CCA rating? I spoke to a BMW dealership and he advised if you are replacing with a non genuine battery it must have exact CCA rating to avoid issues.

Thanks in advance,
Higher is fine. Lower might be an issue, especially for a diesel (they're harder to start).

I have replaced this battery since authoring this thread. The best battery on the market for the E53 is the Deka "Exact Fit" EAS9AGM49. It's AGM/valve regulated and something like 1100CCA.
