2000 hdi erractic idle when cold. - mattyboy
i have a 306hdi estate 2000 w plate 108,000miles. It idles erractic till it gets warm, 5-10mins then it fine. When move off it stutters between 2-4000 rpm then pulls fine. It seems fine when on a steady drive. I have changed fuel filter and checked for metal bits, there aren't any. I replaced fuel relay, the brown one near inner wing. Had all codes checked - there are no codes in ecu. The only thing i haven't changed is the pump in tank. Could this be the problem? Oh and checked for air leaks just in case, none there either. please can someone shed a light its doing my head in, thanks
