Try inserting the key into the drivers door lock and try centrally locking and unlocking all the doors a few times. If this does not reset the valet function try using the key in the drivers door lock and pressing the fob at the same time as locking and unlocking the doors. Even with valet mode engaged you should be able to access the trunk by physically inserting the key into the trunk lock.

Check for obstructions (sorry-have to start here)
1) get to a very quiet place
2) trigger the switch to move the seat
2.a) if you hear an electronic single click, the motor is probably burned out
2.b) if you do not hear the click check the fuses
2.b.1) if not fuse, take to dealer for inspection diagnosis...this should be done free of charge

the datum marks on the eccentric bolt heads are to help reassemble when you have replaced suspension parts to make it easy to set up the camber/castor front wheel tracking you should make a note off the original settings before dismantling use the centre setting ie middle line to dot BUT THE FRONT CAMBER/TRACKINGCASTER SHOULD BE CHECKED ADJUSTED BY A SPECIALIST WITH 4 WHEEL ALIGNMENT KIT

If Gas mixes with water, combustion is impossible. Not only is the fuel bad, the lines and spark plugs are messed up. Water will also mess up the electrical lines and the cars computer.
First, get some gasoline drying solution. That takes a day or two to work. When the water is removed from the gas tank, add fresh 100% gas. Pull all the spark plugs and clean the ends and check the gap for proper distance. Make certain the plugs are clean and dry before you reinsert them into the ports. Dry and clean all spark plug wires. Check you battery also. It should not have corrosion on the poles. If they have a coating, clean them and make perfect contact with the power cables. Try to start the engine now. Good luck.

I'd change the plugs as per this link, and swear by an 'internal service' by chemicals as manufactureed by BG Products available on Ebay (The chemicals are for professional use so stick to the instructions). If you haven't seen this thread, take a look.
