Hi have you ever had the problem of the bonnet hinge making a noise that goes through the dash mines rubbing and making a raket ive tried greasing it but no luck I sorted the problem last time with greasing it but not going away this time
Have you checked to see if there’s play in the bonnet hinges . I’ve never come across this problem one more thing to try the gas shocks disconnect them and see what happens one side at a time hope this helps
