As soon as I stop and check approx. 3 sec. car in idle -> injection

Hello, my car Megane 2 Bjhr. 6/2006 1.9 dci 131 PS 333/AFC 172Tkm, now has a problem! I start the car and when I start the car directly (without the car getting into idle), everything is top. It pulls perfectly, runs normally calmly. so everything is normal. As soon as I stop and run about 3 sec. the car in idle (800 rpm) appears in the display “Injection check and the maintenance key lights” to which the car goes into the emergency running program(Lower U/min m Ax 120 km/h)! I start the car after 3 min. new the error message is gone and it drives back normal as long as I don’t get in the idle (light gas nozzle at the traffic light etc.) prevents that! That’s crazy. What can that be? Topics: Engine, RENAULT Megane Details about the vehicle: Kombi, built in 2006, 131 hp, 1870 ccm, diesel, manual transmission, 172000 km
