You could look at it another way, oh and for the benefit of yourself and others, this is not "grumpy/snipy" or anything else. It is fact.
You could go to a garage, and pay for advice. Not work but advice. Which is possibly the biggest "mickey taking" out. You would have to spend time, and energy, finding a garage that know their way around Range Rovers and can help with your particular issue. You would have to leave your home and take your vehicle to them, and leave it with them. Just for them to throw ideas about, discuss what might be wrong, ask for more detail on symptoms, tell you your veh need diagnostics and charge you a princely sum
OR
You can come on a website, and ask, without so much as a please or a thank you, a group of people, who you do not know have not bothered to introduce yourself to, for free help. Then go in a strop because there was a bit of quite gentle banter.
You chose free help, from people who actually, don't have to help you. People who are doing you a kindness. So maybe a little less 'entitlement' and a little more 'thank you' , is in order.
You will find the help you need on here, but never forget, it is real people at the other side of the screen.
If you still wish help with your problem, wander over the the Range Rover section, and try again
