be careful when you use a screw driver and wd40 that the hood release cable is properly working. I had the same problem, used the wd40 solution, and as of today I now can't open my hood.
I tried pulling on the cable with plyers and it wont budge. Heard I have to cut a wire coat hanger and feed it under the hood to release the mechanism manually. I dont even know if its possible.
not sure exactly what I did but don't do whatever that was.
