That is not 100% chance unfortunately.

Last month, as I was on a larger maintenance process, I took the oportunity to have a look to my TA. There was nothing alarming neither any error flashing beforehand. However the engine was 105,000 km so I took a look at the TAs just to make sure, and bingo! The 7th to 10th gears teeth were obviously damaged and needed care, this is the same pattern for all the actuators.
As a preventive measure I just sent it to rebuild.org.uk and within a week it was back home. Yes, it is much more expensive than only gears fetched on ebay, but a quart of what a brand new OEM worth.
Here is a pic of my gears after 105k km which is self explanatory.

Throttle actuator gears where to buy

Yes my beast has 118k miles on it and actuators were replaced in the 80 k range by bmw along with rod bearings and smg. Im look at the fact that bmw would have used stock replacements and Id like to upgrade the gears before I have issues not after the fact. Same with the rod bearings too

This is 1 big con from bmw there comes no warranty with these things best option to go down is with Abdul if your in America and Jason if your in uk these are the only places which will offer a LIFETIME warranty that was the biggest plus point for me when I done mines and the another plus point is the warranty goes with the car so when you go resale it'll make a big plus factor is Well

I replaced the gears only and they were originally injection molded onto the shafts so you actually have to weaken them with a drill bit and then twist the shaft to crack the gear in half to remove it from the original shaft. Once removed there is a knurl pattern in the end of the shaft and also a flat area that the replacement gear will align to. Since the surface is knurled, you will need the epoxy to fill in to provide the additional surface strength between the shaft and the new gear.

I found a video on you tube for the one that has the shaft already installed by googling bmw e63 throttle actuator gears, then one of the videos to the right ( the next videos in you tube ) showed a guy doing this one. For the Odometer gears ( the ones I did that are just the gears ) there is a video for the S85 engine on their website that is viewable on their site ( their you tube video link does not work )

This was my thought as well, I got the fault only a few times and then changed the gears with th hopes that I did not damage the circuit board too much. If they have not faulted I would think there is some more life left in the circuit boards, just my opinion though.

I do my own maintenance so it is not a big problem if they fail again from a cost perspective, just additional time to replace them again. The task to remove them was not bad at all and now that I have done the process ( I always take the extra time to write down each step the first time so I have the process ) , I would estimate replacing them with complete units would only take about 4 hours.

If I was paying someone to replace them, I would definitely go with complete rebuilt units or new ones as the labor cost would easily make up the difference if they did not last very long with just the gears being replaced.

Yes, mine looked almost exactly like your picture as well after 75,000 miles. I had only gotten the fault a couple of times on mine and could reset it, but knew they were very close to completely failing

Hi, I may pick up a set of these from you. I'm doing rod bearings this month on a 121k 2006 M5 I picked up at 118K. I'm not having any symptoms, just want to do it preventatively. Is it just a part swap or do you need to do any computer calibration/programming when you swap out the parts?

Thank you
Jen

No calibration is required. You just swap the parts out. That's it.

I just sent you a pm.

I have two shops so I always do my own work and am interested in knowledge to fix other peoples cars too.
