Problem: Car “falters” on acceleration when leaving a queue of traffic.

This has occurred most noticeably (and is frightening) at a busy roundabout, about 8 miles after leaving home, the last 4 miles is on straight roads with average speed of 50-60 mph (engine well up to temperature). The short queue of traffic may take 2-3 minutes to clear, during which time the engine is idling.

This was explained at the recent routine service to the local Volvo dealer and I was assured it would be checked. On collecting the car I was told that no faults were found and that the “software had been upgraded” (Routine?!)….but no change.

Coincidentally on longer journeys, starting from cold, the fuel consumption ( based on average fuel indicator) seems to improve if stopped, the engine switched off, and then restarted. Similar to “rebooting” a computer. This is subjective but that is the clear impression.

Have you had any similar comments with this particular model/engine ? Is there a sensor somewhere at fault?
