No Can-bus error but hyper flashing

Hay guys, 

I have recently upgraded my fiesta (mk7 facelift) with LED's (Dipped a few months back all fine, and today High beam, front fogs, front and rear indicator, the side repeaters in the mirror and rear breaks), From my research, the only lights that require can-bus ready bulbs are the front and rear indicator lights. So i went a bought some from Autobulbs direct and they seems to all weak fine. I don't get any form of can-bus error on the dash (as I did when I pulled the original bulbs out and tried the headlights)  so I thought all was going well. Went on my first drive and I got an issue with hyper flashing. 

These are the ones I bought

Any advice would be great!

    Possible poor quality.

    Try using autobeam, see if you have the same issue, if not there's your answer.

    Unfortunately, so many aren't up to scratch.

    It because they are LEDs, they pull less current when used so the system think a bulb has failed causing the fast flashing, you need resistors to to stop this.
