Dear community, I have been hoping for some time now to rule out a problem with my Volvo V50 T5 automatic 220 hp. When driving a motorway with switched-on cruiser he suddenly knocked out of it and thwarted the power. I have restarted the vehicle and was able to continue driving with the error message in the BC ”decreased power”. At the time the vehicle had felt still about 170 hp. After deleting the error memory the error message came since only when I activated the cruiser. In the error memory the following errors were filed / Bosch Tester: – 21AD Long-term mixture control, lower partial load/component function at the control stop – 1230 air mass meter signal too low – 614B outlet shaft control position Faulty From this realization I have now changed the air mass meter, which unfortunately did not bring any improvement. After deleting the fault memory and restarting the vehicle, the error message has not been checked again.
