I had the diff bearing replaced under warranty on my 64 plate FL2 in December 2017. I just spoke to the LR service dept who did the job regarding booking the car in for a Haldex oil and filter change. They told me that these would have been replaced when they did the low level diff repair. Does this sound right??

I note that if one were to buy the low level repair kit independently it contains Haldex oil. MY 09 GS manual in Lago Grey, Wood Co arm rest and side bumper strips - now sold.

Haldex oil has to be done because of the design configuration.

I doubt that the Haldex filter or Haldex pump screen were done..... FL2 HSE Auto Galway Green
