Hi, I have a Roadie Finale with standard 17" wheels and stock tyre sizes.
I've noticed that when the cruise control is activated above 65 or 75 mph, it will engage as expected but automatically disengage once the ECU requires any throttle. i.e. engage cruise above 65 mph, watch boost dial head towards 0 bar, and feel cruise immediately disengage. This problem doesn't occur below 65 mph, and the other features of the stalk remain fully functional at all speeds including the speed limiter function.
Diagnostic steps followed by my smart specialist, amongst others, have included:
- Re-code the cruise control
- Replace reluctors with smartmods reluctors
- Replace driveshafts with OEM driveshafts and reluctors
- Re-code the car for 17" wheels
- Take a live readout whilst driving, which indicated an approx. 3mph difference between front and rear wheels at speeds of 70/80 mph (left/right readings were consistent)
- Check wheel sensors (all in good condition)
- No errors logged, although as Evilution noted, errors will only be logged if the car believes there is an error (values outside of the parameters)
No other problems with the car or odd running; it's only on 22k miles and has had a fair number of sensors and parts changed on a precautionary basis in the year that I've had it. The next step will be to try running the car on a smaller set of standard Roadie wheels, but even if this works, I'd still like a more permanent fix.. any other suggestions?
Thanks!
