Lewis-

We have an issue with the Kodiaq which jolts when changing gear or speed. We took it to an independent garage who diagnosed it as the rear diff which needs replacing and that it needs to be carried out at Skoda only. We then took it to Skoda and told them it was the rear diff but they said they diagnosed it as the Haldex needing a service, changed the oil and filter and it still did the noise / jolting. They then said it was the Haldex pump that needed replacing, which upon replacing, still didn't solve the issue. They have just phoned and said, low and behold, it's the rear diff that needs replacing and it will be £7500! We bought the car from this dealership 18 months ago, 17 plate with 48,000 miles (now on 60,000). It was given a full service and check over beforehand (apparently). Should something like this go at this age and milage and do we have any leg to stand on saying that this should have been identified when purchasing the car, and that we stated it was the rear diff when booking it in? Does anyone have any advice on how to deal with this situation?
