TuningBot DTC Database · v4.37.14
8 manufacturer-specific interpretations across 5 manufacturers in the TuningBot DTC database.
BMWThe control module detected a fault associated with the Solenoid Valve Running Losses Control Circuit Electrical circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by BMW.
DodgeThe control module detected a fault associated with the Idle RPM Hi circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Dodge.
MINIThe control module detected a fault associated with the Valvetronics Actuator Motor Power Supply circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.
PSAThe control module detected a short circuit to battery voltage in the Variable valve lift relay control fault circuit. Documented for the Bosch MED 17.4.x engine ECU (EP6 THP family) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected a short circuit to battery voltage in the Fault in the variable valve lift system circuit. Documented for the Bosch MEV17.4 engine ECU (EP6 1.6 VTi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected a short circuit to ground in the Variable valve gear solenoid valve command circuit. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
VAGThe control module detected a short circuit to ground in the Bank 1 Camshaft Adjustment circuit. This is the manufacturer-specific definition used by Audi.
The control module detected a short circuit to ground in the Bank 1 Camshaft Adjustment circuit. This is the manufacturer-specific definition used by Volkswagen.

Specific fault index within the subsystem.
Diagnostic Trouble Code (8 interpretations). The control module detected a fault associated with the Solenoid Valve Running Losses Control Circuit Electrical circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by BMW.
P1056 is a manufacturer-specific code. In this database it is documented for: BMW, Dodge, MINI, PSA, VAG. The same number can mean something different on other brands.
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
