About P1262

P1262 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.

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.

P1262 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

When the Engine Control Module fires an injector it does not simply apply voltage for a period of time, it ramps the current up to a defined target within a defined window and then holds it. On direct injection engines that ramp is driven from a boosted high voltage supply generated inside the module, and on port injection engines it is driven from battery voltage through the injector winding. The module monitors the current it achieves and compares it against the target. DTC P1262 is stored when the drive current for cylinder 1 fails to reach the required control limit within the expected tim...
