'07 CLS, the ignition key is slightly 'sticky' when removing it from the lock, it doesn't pull out cleanly. Spare one's the same. Any ideas? More of a niggle than anything else, but wondering if it'll get worse.

Locksmiths "lubricate" locks with graphite, because using oil type lubricants tends to bung up the movement with a gunge that consists of the oil base mixed with the accumulated detritus.
Presuming that you won't have any graphite for locks, a popular approach is to find an old pencil (as soft a grade as possible) and rub it all over the blade of your key. Repeat a few times, and the action should transfer some of the pencil's graphite into the lock thereby freeing up the action.
Hth.
 
Does the CLS have one of these? If so, could be the beginning of the ESL motor failure issue

+1 for the above ⬆️ Not experienced it myself but if fails with the steering lock on I believe it becomes quite a big job , especially if the car is parked away from home .

If it is a traditional key Lidl do graphite lubricant in a can , but obviously being Lidl you have to wait for it to pop up randomly in the middle isle !.

Can you hear the ESL every time you insert/extract the key ?
It's often that silly little Scalextric motor that fails; as Pete says apparently a relatively easy job to replace until it fails with the wheel in the locked position, when it becomes a complete ballache.

It makes the brief whirring noise every time. I squirted a bit of silicone spray in there, seems fine now.
