Volvo V50 2.0D no readout when engine is cold

Hello Forum With my Volvo V50 2.0D 2006 136Ps the following problem has arisen: If the car is started after longer standing time or if the external temperatures fall below 5 degrees then the car hardly takes on gas during the ride. Climbs can then hardly be overcome since the turbocharger is not switched on. Then changes after a few minutes when the engine has become warm and you can call up the 100kW as usual. From the symtom it is similar to here. r:https://www.motor-talk.de/…/…sistung-bei-kaltem-motor-t3141429.html What was changed? Turbocharger new Charge pressure control valve DPF some vacuum hoses Suction tube flap yesterday was still the AGR. After that there was always a small improvement to feel but the performance problem remains with cold engine. If you want to give full throttle in the cold state (which of course you should not) the car already goes into the emergency running program. I don’t know the exact codes anymore. Motor starts without problems. Low pressure system seems to be tight as well. What else could I try? My workshops incl. friendly have no advice. Thanks
