The conditions : downhill on a wet road (not too wet)
How I was driving : deceleration and was going less than 30kph and braking for the upcoming stop at the botton of the small downhill.
That's why I found it weird to happen at that time. Only other time I saw this error was after disconnecting the battery (and I did check the battery connection to make sure). Did try to replicate the issue in similar condition and 150km later still didnt came back. Will keep cobb removed for a week at least to see what happens.
