I'm driving a 2008 LR2, In may last year, the triangle yellow light turned on while I was driving in highway. Since then, three problems have been displayed as "transmission fault","HDC system unavailable",“special problem off”. However, you can feel nothing wrong when you drive it. This morning, my friend helped me check and found code: U0136 "lost communication with differential control module-rear". Did anyone meet the same problem and how can it be fixed? And how much will I pay if I go to dealer to repair.
