CSL DD 8NM - sudden wheel disconnect during driving (solution)
Hello fellow sim racers,
I'd like to share a solution I have found but apprently nobody seemed to have mentioned in the forum posts I have gone through.
I have had the issue on two different wheels, the problem occured with both at the same rate.
Before the CSL DD I used to have a CSW 2.5 on which I have never experienced this behaviour.
- wheel hangs itself during driving
Shifting does not work anymore then, and shortly thereafter (several seconds) the FFB drops completely. Also the display and lights on the wheel are frozen at this point. The wheel rotation and pedals (connected to the base) keep working. Other than rebooting the whole PC I found out simply removing and putting the wheel back on the base solves that problem, which also resolves FFB.
- Sudden brief FFB drops :
Sometimes, the FFB feels to "switch" suddenly to a (for me) steady low value and after a while (1 to x secs) comes back up again. This feels very unnatural, it can happen nearly everywhere, on braking , in the middle of a corner (also while coasting) and sometimes even on a straight and I don't think it is a simple grip loss as the power loss is far to too much.
On the forum there are a number of people describing similar problems, here is an link excerpt
I tried (during several weeks)
- driver and FW updates including down- and upgrades to 415, 429, 439, 447 (now) and several betas inbetween (ie 434, 440, ..)
- switched to another USB cable
- added multiple ferrite cores to both ends of the cable
- switch to other USB ports (front panel and back (mainboard))
- added additional USB PCIex riser card
All of this did not help with the problem and I was about to sell the whole lot and move on .
It appeared to me some tracks were more prone to this problem than others for some strange reasons, and sometimes it even seemed to occur on the same corners more often than on others
At some point I noticed in my anger the wheel disconnects when pulling upwards, which led to the conclusion on some occasions the QR wheel attachment cannot cope with the forces applied to the wheel and this movement had a relation to the corners.
In conclusion imo the shaft and connector tolerances are too big to use the wheel without tightening screw so one or more pins get (briefly) disconnected when an external force is applied, which then in turn hangs the wheel controller.
Solution (for me) :
The fix was (in my case) to tighten the connection between the wheelbase and the wheel using a M6 plastic screw and rubber washers, like shown in the picture.
I haven't had a problem since and I am a happy customer again.
