Hi, I have the same error message and want to change the throttle body. Can you just fit a new one or does it need programming. Thanks for your help.

No coding is necessary. It's a pretty straightforward replacement.

Thanks for the reply, I have had it off to clean and it was really gunked up
with black oil and soot deposits. I have now had the red dpf filter fault come up
and it is at present having the dpf removed and deep cleaned under warranty.
I have read on here that it’s the throttle body that causes this but I can’t get
the dealer to change it because they think just cleaning the dpf will fix it.
I think I will just do it myself £500 is a small price to pay for piece of mind.

The dealers are clueless. The throttle causes the error code and the error code suspends DPF regeneration. The DPF will clog again. Go to YouTube and look up a guy called OReillys Mobile Mechanics. He's put out some good videos on this issue on JLR vehicles and shows how to clean the DPF without removing it.

They did a software update when I had my throttle body replaced. Don’t completely know why it had to be done, but it’s been fine since the throttle body change.
I was also getting DPF issues and had it cleaned after numerous warning lights appeared, and kept appearing after the DPF clean, and didn’t stop until throttle body changed.
It’s been good for 18+ months now, whereas it was about a day until the throttle body was changed
