Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Here are some thoughts for you, I suspect the cable or rails since your motor seems to be working just fine:

Suggestion
If you're not-so lucky the cable may be beginning to fail in one way or another; getting stretched or chewed, probably, in which case you'll need to replace the driving mechanism:
Leading evidence: 'cable or rails since your motor seems' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'cable or rails since your motor seems' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace driving mechanism' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have an '05 C4S. The sunroof worked perfectly then one day i hit the one touch close button and it sends the sunroof back but right when its about to close it sends the sunroof back to open. at first i was able to just hold the close button and it would close properly, but then that stopped so i had to hold the tilt button down to get it to close all the way, it would then send the sunroof to tilt mode and open, id then press the close button again and it would finally close properly.
Any ideas as to whats going on??
Here are some thoughts for you, I suspect the cable or rails since your motor seems to be working just fine:
If you're lucky you may just have some gunk/buildup on the rails themselves. Give them a good clean and then lube with some lithium grease or some Teflon grease.
If you're not-so lucky the cable may be beginning to fail in one way or another; getting stretched or chewed, probably, in which case you'll need to replace the driving mechanism:

If it is the cable that's beginning to fail you're only going to have so many chances to observe this thing and fiddle with it before it fails completely and your job (or your mechanic's job) gets just that much harder because it will be stuck and won't move as freely for positioning and removal during your repair.
If your battery has recently been dead or has been replaced you may need to "relearn" the sunroof , by opening completely then release the button and hit open again for a few seconds, then do the same for close, close completely then release and hit close again for a few seconds.
As mentioned by DR Strangelove cleaning and lube the slides is always a good idea, and if these two scenarios doesn't work, you could have a failing cable/slide/motor problem.
This type of thing happens to my sunroof and even windows from time to time... I just hold the buttons to close them and they relearn. Not a huge deal.
