Sounds like you may have a leak in the airmatic suspension struts on the rear. These govern the height of the car in different modes. Not an immediate problem unless you are loosing a visible amount of fluid but it will only get worse.

To check if you have airmatic you will have buttons just behind the gear lever which can be used to put the car in to a stiffer, lower mode or to raise it for rough ground

The electrical connector "o" rings leak on the 722.6 transmissions and there is an updated "o" ring. If you remove the connector by sliding the lock upwards there is a 7mm. bolt holding the housing onto the vavle body plate located in the center of the pin connector on trans. Remove that 7mm. and pull housing out of trans. there are 2 "o" rings on the pin connecter and one on the harness connector. M.B. sells the 2 for the pin connector and the harness connector comes with the hole connector but you have to remove all the pins out of the old one. The harness connector is not the problem just replace the 2 on the transmission pin connector. Make sure you add M.B. electrohydraulic trans. fluid to the transmission. You will have to purchase a dipstick from the dealer because there is onlya housing tube. The trans has a red color lock and the oil a black color lock. They are right next to each other so be careful not to confuse the 2. I have seen them leak bad enough to fill the trans computer full of oil- The E.T.C. module is located in the r.f. foot well in the false floor under carpet. I do not know what circuit board you are refering to. I'm assuming it is the valvebody solonoid plate. After repair I would recommend having the car scanned and cleared for codes assuming the module is not full of a.t.f.. You may be able to clear the codes by disconnecting battery neg. for at least an hour to drain capacitors but it is always best to have car scanned. Good luck

Most likely cause is the 'stop lamp switch'
It is a electric switch located on the brake pedal inside the car, about half way up on the brake pedal.
Pretty cheap too, I think the switch is only like $25 bucks.
2 connectors on the switch and then it turns out.
hope that helps
Fan relay should be in black box near frewall

If you have a good relationship with the dealer, they may not charge you for the radio code. The other place that the code may be is written in the back pages of your manual. If the dealer wants to charge you a crazy amount, try www.radio-code.com or carfax.com may have the information to your car's radio code. Good luck and hope this helps.

You can try to disconnect the battery to clear the system. IF this does not work, You need to have the system reset by Mercedes Benz Dealer or a mechanic who has the system to do that.
