Hey guys.
I was driving home from work yesterday, brakes not on, going down the street at about 40k's and all of a sudden I got an abs fault warning on the LCD in the cluster and the dash abs light came on as well, I continued to drive home (was about 30 seconds from home), turned the car off. Turned it onto accessories so it would preform the system check, same issue. Turned the car off again and repeated and again got the error. Today I started the car and got no error messages and the abs light was no longer on, it has also stayed off and there seems to be no issues with the system. As a side note I had the pads and rotors changed about 2 weeks ago from a trusted family friend (who is a mechanic).

Should I be overly concerned or just treat it as a cars will be cars thing, due to there no longer being an error message?
