Re: Speedometer not working, spoiler up, ESP/BAS and other warning lights on

All of the symptoms mentioned can be caused by a bad traction control relay in the relay control module.
Open the RCM (Video on YouTube) reinstall it, turn the key to the ON position.
2 of the 3 middle relays should stay engaged. If only one, you found the problem.

If only 1, turn off car. Manually close the failed relay (toothpick works).
Start car. You should be able to lower the wing. Other faults will clear after running for a bit.

Email me for RCM repair info if needed.
