Hello everyone, my 118d automatic, 59 plate, has intermittent stuttering and then stalls while decelerating to a halt. This issue occurs only when the engine is cold, primarily during the first mile of driving.
Last year, I replaced the gasoline filter, which significantly decreased the frequency of stalling; nevertheless, it now occurs almost every morning. The vehicle restarts without issue after stalling, and there are no warning lights illuminated on the dashboard.
I believed the filter was expected to last for more than a year. Is it possible that it is anything different?
Would it be advisable to remove the EGR for the purpose of cleaning it?
Additionally, I am uncertain if it is pertinent, but the engine operates with considerable noise and roughness at idle. I replaced the belt tensioner last year, which significantly improved performance; however, could the tensioner require replacement once more? Are these issues interconnected?
