My brand new RRS after 2500 miles started to use more and more fuel and very jerky gear change, then about a week later the Restricted Performance Red light came on.

I was advised my LR Assistance that it needed to go back to the supplying dealer, problem with engine mapping and a sensor?! They had my vehicle for a week and apparently they replaced a faulty pipe to the DPF and a sensor. Has anyone had this problem?
