Hi,

For some time now, my car has been getting into limp mode randomly while driving. The car struggles/hesitates while accelerating with the DSC (traction control) light on. I plugged into a computer a while back and it showed a code related to the clock spring. I don't remember what code it was. I have an appointment scheduled to get that fixed already. However, my car has also recently begun to cold start quite badly. It's like it struggles to start in both neutral and gear when cold (I'll attach a video if needed). It starts fine when the engine is warmed up. After these bad cold starts the DSC light comes up right away and the car is in limp mode for the entire drive. I'll get it fixed in some time anyway, but I was just purely wondering - could these bad starts be caused by the bad clock spring? No other lights show when the car starts badly, only the DSC light.

I didn't see the video. I don't think a bad clock spring can cause hard starting; I have seen a dirty throttle body cause an issue though.

Here are two guides to help us fix the problem and I have left instructions in the images below to help as well:

and

and

Check out the images (below). Please let us know what happens. If you follow the instructions in the guide, you should not have to reset the throttle actuator.

Thanks for the videos, they help. I would also re-run the codes using a can scanner and if nothing comes up, please follow the guides above. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Please go over these guides and report back.
