BMW 318i Touring, automatic,2001. The engine (83000 miles)

Resolved Question:

BMW 318i Touring, automatic,2001.
The engine (83000 miles) runs well with normal acceleration and speed.
But, just occasionally, say once on most urban journeys the engine fails to pick up from a stop or pause, creeping forward for a couple of seconds before responding normally to the pedal.
On rare occasions the engine will judder and cut out though it immediately fires up again when restarted.
No error messages have shown up on the diagnostic test.
Please let me know if this a known problem or of any clues to the likely cause.
Many thanks

thank you for your attention to the rating requirement
this is not a common problem but the probably causes would be a throttle body issue or fuel supply issue.
the way to avoid guess work in diagnosing this will be to have a bmw scan tool hooked up to the vehicle to monitor all inputs and outputs from engine control while replicating the issue. Any good BMW garage can preform this testing for a 1-2 hour labor charge.
