Renault Laguna III - 2.0dCI Sport Tourer Owner's Review - Alanovich
Maybe ping is the wrong word. The last time one broke on me, whilst on the M25 in a tropical downpour, and on the way to a garage to have it changed (natch), the noise was more like BANGTHUDDUGGADUGGADUGGADUGGAduggaduggaduggastop. Followed by bucking folloxes, at an even louder volume.
