Anhartic Posted October 3 Share Posted October 3 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?

DownContent Posted October 3 Share Posted October 3 If the EGR valve is vacuum-operated, attempt to disconnect the vacuum pipe and observe any changes. Link to comment Share on other sites More sharing options...
Anhartic Posted October 3 Author Share Posted October 3 There are two slender tubes connected to the EGR system in my vehicle. Would it be safe to operate the automobile if I detach these two tubes? Should I remove one hose, and if so, should I secure the severed hose or leave it untethered? Link to comment Share on other sites More sharing options...

Anhartic Posted October 3 Author Share Posted October 3 I will do that; do you have any suggestions on what to examine if it is not an EGR problem? Link to comment Share on other sites More sharing options...
DownContent Posted October 3 Share Posted October 3 Do not disconnect the electronic EGR pipes, since this will result in coolant loss. Link to comment Share on other sites More sharing options...
Anhartic Posted October 3 Author Share Posted October 3 Understood. Are there other methods to verify it? All the information I have seen indicates that the EGR is becoming stuck in either the open or closed position. Link to comment Share on other sites More sharing options...
DownContent Posted October 3 Share Posted October 3 Remove the plastic cover on the EGR and manually manipulate it; it should effortlessly open completely and return to a fully closed position due to the spring mechanism. Link to comment Share on other sites More sharing options...
Sumoto Posted October 3 Share Posted October 3 The dome-shaped plastic should simply detach. Ensure it is unobstructed and that the little arm behind the cover is not ajar. Link to comment Share on other sites More sharing options...
