manifold and other question from a new 75 owner

[the dutch guy]

Good day everyones.

first i would liek to apolozige for some of the questions i have, but after hours of digging the forum i cannto find a decent answer to some questions i have.
i hope you all have the patience to help me answer these.

I got my rover 75 2.0 V6 last week from my dad, he could not live with the clear coat being destroyed more and more leaving many ugly patches everywere and lots of little dents everywere. i am going to wrap the car to solve this but that is for another time.

first question i have is the parking sensors, when selecting reverse i hear one 5 second long loud beep from the rear seats and then nothing. its completly dead until i reastart the car and then still only that beep. i assume soemthing is wrong but how to diagnose what is wrong? i am a professional driver but this exxon valdez sized oil tanker's rear is impossible to find when parking, so i would like to get those working again.

second question: i got a slight "noise" from the manifold. its quite slight so i expect this is the early stages of the death rattle i read about. first i am going to rebuild the motors, they are really easy to get to so i can check the rod but i feel that the power valves dont do what they supposed to do and 1 or more cyclinders is not "valving" like they should, its incredibly lazy under 3k rpm. i had a 2.5 v6 and 3.7 V6 alfa and this engine feels like half frozen molasses under 3k.
i do want to get a replacement manifold but they are impossible to find. if a member here has one (broken or not) then i am interested in buying it. i might be able to print a replacement rod but i need a manifold to test this with or replace it so can mess with one outside the car and get the valves working like they should and make a cheaper fix for everyone as the price for a new one is 1300 english roebels right now.

third question:
power window. i have the EU model but for some stupid reason only the passenger (right) side has the auto up-down mode, the (left) driver side is not. its also quite iffy in stopping after a few inches. they forgot to program the windows for the EU or so, can this be changed and where do i get the buttons as that is probably the reason why it stops going up. can i switch around the buttons if i remove the panel?

4th: the lcd screen on the dash is totally unreadable, it is missing 70% of the vertical lines. is this dodgy conecctions that just need a resolder or is the lcd simply done? i really like to get this proper again.

5th: also the recirc function of the AC is murder-inducing, how can i force it to stop it being on auto and just always use fresh air? i am so annoyed needing to press that button twice every time i start the car. if someone knows the adress of the guy that thought of that and a nearest place where they sell pliers i want to have a minute with the guy and his teeth in a quiet room.

6th: how can i have the lights switched by the igintion? every car i had already had this feature (italians) or i made some wiring changes so i worked like it should.


i hope you guys can help me with the above issues.

ps: what is it with the engine numbering? on this forum i see you calling the V6 the K6V but on wifipedia its 20K4N.
