P276D is the general current code for the motor of auxiliary transmission pump B: the measured current does not fit the commanded speed or load, without the module saying whether it is too low or too high. The narrower siblings P276E and P276F carry that distinction, and P0C26 is the same check for pump A. No manufacturer documents P276D publicly. For the component, Audi's bulletin 34-17-25 names the gear oil pump V553 as pump B in its 0CJ, 0CK and 0CL dual-clutch gearboxes and describes an assembly defect that made the pump rattle. CARB requires that electric actuators are checked for proper function. Worn brushes or bearings, a jammed impeller, contaminated fluid or a bad ground typically change the current draw before the pump fails.

Likely causes

Worn bearings or binding impeller in pump B
Contaminated or wrong transmission fluid
Poor ground or connector resistance at the pump

Symptoms

  • Noise from the pump area
  • Transmission warning lamp
  • Stop-start or shift quality restricted
