Managed to pull the codes from my ECU (very good sticky!) and only had this: SSSSSS - Speedometer sensor.
Any ideas of what it\'ll be? I assume it\'s just that but my speedo is spot on with my GPS, so I know it\'s working fine! Would it have been just a temporary error?
First off I would reset the code down. Then go for a drive about and see if the code returns.
If it does look at this factory service manual
