Hi, i have quite a few issues with my S124 that i would like to get sorted out:

1. The oil pressure gauge is acting weird, when the engine is cold it shows the pressure correctly but when the engine get warm and i make a sharp turn the oil pressure drops to zero and stays there until i drive over a bump or something like that.

2. The outside temperature sensor, when i start the car it shows for a few seconds that theres -38C and then the display just goes blank.

3. Last week i bought my car headlight washers, the full set, but i couldn't find a wiring diagram anywhere, can someone tell me how to wire them correctly ?

4. The cruise controll on my car doesn't work, i've read that the typical issue is with the AMP and i just have to resolder every connection there? Everything on the cc lever is in german so i don't actually know how to turn the cc on but i've tried moving it anyway it goes and it doesn't do anything

5. The SRS light in my dashboard is on constantly and my horn is also not working, i read somewhere that these things are somehow connected, but i couldn't find anywhere how to fix this

6. And finally my cars sunroof only tilts and doesn't slide back, when it tries to slide back it gets stuck somehow, is this a common issue and what could be the cause of it ?

I would be realy happy if i could get anwsers to atlest some of these problems , also i am from estonia so excuse me if my english is bad, thank you
