This was what was shown when booking the 2 year service, very clearly stating “Replace rear differential oil.”.
I also have an email from Toyota GB that states:
“As we are the manufacturer and distributor of new vehicles here at TGB we do not manage any of our centres as they are all franchises and have their own in-house complaints process when it comes to being unhappy with the service they have provided.
However, you are correct, the rear differential oil is listed on our website as needing replacing at 2yrs/20k service. Therefore, I have passed the details of your complaint directly to service manager at <dealership>.
I would like to apologise for your experience, and I hope that they can work with you to provide a solution.”

Hope this helps.
