First had this issue 6 months ago, Engine slowly stalled then when attempting to restart it died out after 10-15 seconds of running with some smoke coming from the front of the engine.
Diagnosis was showing DPF filter so cleaned out DPF and inlet manifold only to still have the same issue.
Diagnosed again seemed to display an issue with the fuel supply so switched the fuel rail and changed the battery car was then running fine and actually passed the new style MOT! Up until last week following a service inc oils/filter changes. Car seemed to lose power during driving and eventually stall and when attempting to restart it died out after 10-15 seconds of running.
Engine would continue to cut out after starting the ignition. Diagnosed again when it began to run for a while and attempted to drive a short distance. There seemed a slight difference within the airflow levels to and from the turbo so considering sending turbo to a specialist but thought I would reach out first to see if anyone has had a similar issue before?
