Range Rover Sport 2009 HSE Diesel Auto

I purchased my Range Rover Sport 2.7 September last year, it has thrown every light available up on the dash, I've had numerous repairs valve block, all associated pipes, break light switch yaw sensor, 3 replacement injectors but still I get the same 3 lights on my dash, the triangle warning light and subsequent fault warning, loss of transmission (limp mode) park brake fault etc all the usual, even the land Rover diagnostic gives loads of codes, most of which should have been eliminated with the repairs, I am at a loss as what to do next, I'm throwing money at it to no avail, the guy who's done the repairs says he's not doing anymore work on my car, very professional. IDEAS!!

Where are you located? - it'll help with recommendations of where to take it next. Without specific DTC's or a proper narrative of what/when/with conditions, it's impossible to suggest a remedy other that 'try this place'.
