Code Definition

P1282 — Fuel metering solenoid open circuit

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Audi

About P1282

P1282 is a manufacturer-specific powertrain diagnostic trouble code recorded for Audi vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1282 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1282 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The fuel metering solenoid on the Audi and Volkswagen diesel injection pump, commonly called the quantity adjuster, controls how much fuel the pump delivers on each stroke. The Engine Control Module feeds it battery voltage and switches the ground side with a variable duty cycle to move the metering element against a return spring, while a position sensor reports the actual position back for closed loop control. Because current must flow through the solenoid winding for the module to have any authority, the ECM can identify a broken circuit from the absence of current when it commands the sole...
