Main dealer uses wrong fluid in LSD
Discussion
I recently noticed vibration coming from the rear diff at parking speeds whilst turning. Likewise, also a few uncharacteristic clunks.
This all occurred after a major service was carried out by the main dealer. I asked the dealer if they had changed the diff fluid during the service. They confirmed they had.
I made an appointment with the dealer and their tech confirmed my suspicions that the issue was most likely the rear diff.
The dealer has since confirmed that they made a mistake when the car was serviced and replaced the diff fluids with the wrong type.
The dealer is adamant that they can just flush the diff and replenish with the correct fluid.
Between the service and the identification of the issue, the car has covered several thousand miles. I am of the opinion that there is no way of knowing what damage could have been done and that the diff should be replaced.
I'd appreciate your thoughts.

Depends what diff is in it, and how "wrong" the oil was really, but does sound like they should be fixing it.
It maybe that an oil change will sort it out without any damage, like i said all depends how different the oils are, and if any damage has been done, simply changing the spec of the oil may sort it out

What car is it, age etc?
Perhaps get them to flush it and replace the fluid but extend/add a warranty to cover the diff? Can't see why they would agree to replace the diff if it operates perfectly with new fluid, but them standing behind what they are saying would seem reasonable.
As per advice from Neal, get them (in writing) to agree to warranty the diff for [x] years or until you sell it, or if they refuse to play ball get them to remove it and an inspection undertaken on it - whilst they lend you a top of the range courtesy car for the day(s)...Perhaps get them to flush it and replace the fluid but extend/add a warranty to cover the diff?

This thread fills me with dread… Our BMW X5M is due a rear diff oil change at it’s next service. It has three chambers with the outer ones requiring a specific fill quantity and type, each slightly different (560ml and 580ml) and the centre requiring normal diff oil but also different weight…. What could go wrong!
