I think I remember vaguely the thread you read and the bar is not under the bonnet but under the dash and is secured by a bolt that has to be accessed under the bonnet. It's more a strip of metal and you can see it in the picture, courtesy of Sarge, the shiny strip extending to the bottom of the windscreen in line with the steering wheel. The strip is secured by a bolt at the windscreen end and was loose and the strip vibrated making an annoying tapping noise.I have a knocking coming from the centre of the dash,I read on the forum about a bolt that had come loose attached to a bar under the bonnet,I cannot now find the thread with the photos and location of the said culprit....can u help
That sounds very likely the culprit, rubber nipple???? Don't think about it get a quality refurbished wiper from Paul(@depronman).Thanks to you both ,I’ll check on these, also it was suggested maybe the wiper arm banging on screen,when I first looked at the wiper arms there was a small rubber nipple attached to the arm it has now disappeared,but I’ll do a thorough check
