It sounds like poor grounding to me. Clean all of the earth grounds with some fine sandpaper, and then see what happens.

Default Finally Solved!

Hi guys, thanks for all the help and suggestions. I have solved this a few weeks ago, but haven't had the time to post. Anyway, after changing the SPARK PLUGS, PVC valve, and changing around the COILS, the problem was still there. I took it back, and the mechanic did a long testdrive. It turned out to be the MAF sensor ( which I did suspect, and cleaned myself but that didn't help). They had a used spare at the workshop, and when plugged in, the car suddenly woke up So now I am happy. (for now, knock on wood 3 times )

About the lights, I changed the left XENARC lamp, and it stopped blinking, but then the righ lamp started to do that. I took the battery poles and cleaned them with sandpaper, also noticed the two drain plugs in the trunk were open ( I could see the ground) no wonder there was moist back there. After I did this, I installed a brand new lamp on the right side, and now NO blinking I went for the cool blue intense, looks much much better.

I have also noticed that the pedals were not adjusting further than 0.5 mm, I though this couldn't be true, after taking the plastic cover off, I found the gear cracked

Anyway, good luck to all

The adjustable pedals will do that if you have the pedals in the lowest position.

There is nothing to take the pressure off the adjusting mechanism when you are braking. If someone leaves the pedal all the way down and drives for a while that way. The pedals will get stuck and you will only get a clunk when you try to adjust them. As you found out the gear gets damaged. The gear is not available separately and the entire mechanism is pretty expensive.

Have you done any searching because this has been brought up before and solved?
