Honda CR-V differential seized

I took my Honda CR-V into the main dealer for a service recently, only to be told that the central differential is seized and requires to be heated up in order to un-seize it. They want £400 to do this. Is this a common problem with CR-V's? And is £400 a fair price?
Yes, always has been on CR-Vs. It's the rear diff that has seized, probably due to water ingress. £400 is reasonable.
