Audi A6 1997 2.8. I cannot open open my bonnet of my car. The lever is loose with a cable connected. The grey tab doesnt come out of the grill. I have taken the grill off and can only see one 10 mm nut that holds the latch on. Am i going about it the right way? I have seen other links that state you should see two bolts and the third is hard to get to.. Help i need a new headlight bulb and washer fluid. See the pics in my album. Thanks
