Hi! First, I congratulate all of you, for the excellent forum and I thank you for allowing me to be part of it. My question is the following: My LR2, has hesitation, reduce engine performance message and codes P2103 and P2105. When these codes come out, do I have to change the throttle body? How can I check if the throttle body is damaged?
Thank you very much for the help you can give me.

I don't know how you test the throttle body for those codes but what I can tell you is if you have to replace the throttle body, it has to be coded to the ECU and BCU, i.e., married with JLR SDD or some similar programmer & software.

Try cleaning it first.

I see, first I need to clean the throttle body and its not working, I'll have to buy a new one and take it to program. Where can I take it to program? Is only at the LR dealer, or can be in other place?
Thanks for the information, it is very helpful for me.

Merlin, excellent video.
Asking for myself. On my old D2 I used electrical cleaner spray for the MAF..

Could I use the same on the FL2 or do I have to buy proper MAF cleaner?

I don't know about electrical cleaner, it's probably about the same stuff but I'm not sure I'd take a chance...
