2004 Land Rover Range Rover Questions

My 04 HSE shows a check coolant light. I can't get the cap in the reservoir to budge. The engine is cold. Righty tighty lefty Lucy right?

The inside of my range is sagging down- the cloth- it almost touches my husband's head how much will it cost to change it and why does that occurred?

I have a 2004 range rover hse I bought from carson cars about 1year and 3 months ago its been great I had a guy check it out when I bought it and he said there's an exhaust leak anyway I let my girlfriends niece drive it and she accidently turned the hdc on and it went out and ever since then ive been having problems and now the car starts up loud and if I eccelereate the rpm dhoots up to 4 and mph wont go past 30-33 mph. can somebody identify the problem

still getting the check engine light? why?

Not sure what's the problem this time.... Also I need to find out where can I purchase a new volume button RR 2004

The knocking noise seems to last just a few seconds after the start up but then quiets down.

The fold in feature doesn't work as well. It folds in but wont stay in.

4 ways come on and keep blinking. I think it may be the anti theft system. I need to know how to disable it or over ride it. The code that came up is P01000 even. Any help would be great. Thanks.

When I turn over the ignition the engine will fire for a few seconds and die. I used my OBDII tool and it's giving the following codes,P0120,P0123,P0223 and P0103. I've sprayed cleaner on the MAF and checked the connections to the throttle body and anything else that seems to be related. This problemcameon all at once one morning with no previous symptoms. I'm stumped. Help please
