What P276A means
P276A means the power feed to the motor of a second electric transmission fluid pump, labelled B, is interrupted. Such pumps keep hydraulic pressure or lubrication alive when the engine-driven pump is idle, for instance during stop-start or in a dual-clutch gearbox. No manufacturer documents P276A publicly. Audi shows what pump B is in bulletin 34-17-25 for the 2017 A4, A5, A6 and 2018 Q5 with seven-speed dual-clutch units 0CJ, 0CK and 0CL: the gear oil pump V553, which reports supply faults to the TCM under P276B00. CARB requires such actuators to be checked for open circuits. A blown fuse, a corroded pump connector or a broken supply wire are typical; with the pump dead the gearbox may restrict stop-start or limit performance.
P276A at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P276A
- Transmission warning lamp
- Stop-start deactivated
- Reduced performance or limp mode in some designs
Common causes of P276A
- Most likelyBlown fuse in the pump supply
- PossibleCorroded or oil-contaminated pump connector
- PossibleBroken supply wire or relay contact
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P276A means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 6A | The exact fault in that area. |
What to do next
- Note P276A and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P276A
What does P276A mean?
P276A means "Electric/Auxiliary Transmission Fluid Pump B Motor Supply Voltage Circuit/Open". P276A means the power feed to the motor of a second electric transmission fluid pump, labelled B, is interrupted. It is a generic code, so it means the same on every make.
Is it safe to drive with P276A?
Drive gently and only to a workshop. With P276A the car can go into limp mode (reduced power) to protect itself.
Will P276A fail an emissions test?
P276A is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P276A to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P276A clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
