Battery goes flat overnight on clk 230 coupe - 2007 Mercedes-Benz C-Class

No they are not the same panel.

wheel bearings should have no play at all The correct adjustment is no preload -no end float with the adjustment nut moved slightly to preload to fit the pin.
It is happening on full lock ,check the full lock stop as the tyre may be hitting on the suspension or inner guard.

MB doesn't use a reset switch (AKA Inertia switch) for the fuel pump

Looks like a failed relay:
"I sat in the car and started pushing the roll bar button. We heard a click every time I pushed it. My brother was at the back of the car and was trying to hear where the clicking was coming from. He realized it was coming from a relay switch so he took a screwdriver and tapped the top of the relay and **BAM** everything starts working! So through that we realized it was a bad relay".

somthing inside your car is puling amps

in the old days people put cardboard in front of the radiator

Go to any Automotive Parts Supplier (Advance Auto Parts) and tell them that you want a 9 volt battery backup that plugs into the cigarette lighter.......Or if you have a jump box,you with a 12 volt outlet plug on it,buy the cord that connects the outlet plug on jump box to the cigarette lighter outlet plug in the car.......Either option will give you the juice that you need.....I just hope that your boot is electronically operated

to replace engine oil
with oil filter 8 qts
with out oil filter 7.5 qts

If you want to go with the same style battery, or if that's what is reccomended, just call your nearest mercedes dealership, ask for service and explain your situation, and ask if there is an alternative.
hope this helps
