Check the brake fluid level. Not sure if this is connected or not, but I have both front wheel bearings done. Got a guy to do it as I don't have a press.
On each occasion, As soon as I got into the car and drove , it flash STOP once, I stopped, turned car off/on and it was fine.
THis is the only time I have had "stop" apprearing without any other info.
As previously advise dget is scanned as soon as.
