Speedometer Cutting Out on BF MKII XR6 Turbo

[007BFXR6TURBO]

Hi All,

 

I'm experiencing the speedometer cut out while driving. Currently, the car is a weekender and doesn't get used on the weekdays.

 

I started experiencing this issue when I was driving and I pushed the car hard of the line and revs needle will work, but the speed needle will cut out. I have been able to turn the car off and start it back up and drive normal and I do not experience any issues with the speedo needle working again.

 

I have tried to push the car off the line at different intervals in relation to the acceleration force. When driving normal from a stand still its fine, then upping the intensity by 10 percent increments it is okay.  I have pushed it gradually to about 50-60% acceleration. I have noticed when I go harder than that or like a heavy foot where I'm asking the car to pick up speed instantly, is when the speedo cuts out. 

 

On the cluster, the ABS and ETC light appear for the inital few seconds when the car is picking up speed and then dissappears, not sure if that is a signal to a related problem or problem identifier. 

 

Would anyone know what may be causing the speedo to cut out or where to begin with troubleshooting the problem?

 

Thanks guys.

that's a pretty weird issue... something to do with the throttle wiring, I guess?

 

Any trouble-codes?
