Hi Intisar;

    This is typical of manual transmission 5k Audis. As a fuel saving
measure, the ECU shuts off the fuel to the engine on deceleration and only
restarts fuel flow when the RPM drops to about 1500. At low speed in low
gear this can result in a jerky ride. I've found it can be avoided if you
are careful with the accelerator i.e don't back off completely.
