I have a 55 Reg Boxster S, 22,000mls. Over the past 4-5 months it's developed a knocking sound mainly on the right hand side over my shoulder, and intermittently on the left side. Talked to Porsche Hatfield who were very helpful, and they said it was the roof bushes that needed some Vaseline applied. I did this and still no good. The interesting thing is that after 5-6 odd miles it disappears and doesnt return until I take it out on the road the next day "¦.. ideas anyone....before a book it in with them??
Cheers Mike
