Hardcore MB Enthusiast
Nine !! at about £40 each from MB , that's just being greedy . I have only seen genuine MB ones I guess the Chinese can't be bothered copying them because of low volume sales.If your anywhere near North Wales, pop over, I have the tool.
Got it free from my local main dealer mechanic servicing my car.
He had nine of them in his tool box and after handing car over I mentioned how the hell do I adjust washer jets on my E Class, so went back in and gave me one of his.
Great guy
