Hi all, I have a 1998 C250TD that has developed a worsening intermittent fault on starting... Essentially when you turn the key the engine just clunks (it doesn't turn over), then when you try again the engine will start normally. This clunking can happen once, twice or sometime three times before starting or it will not happen at all and the car will start first time... Any ideas what it could be, perhaps the starter motor is sticking?... Any advice welcome!
