P06DA on Mercedes-Benz
Engine Oil Pressure Control Circuit/Open
P06DA on Mercedes-Benz vehicles indicates engine oil pressure control circuit/open. Au7o has documented this code across 1 Mercedes-Benz model — most commonly on GLA. This code indicates the engine computer detected an open circuit (or other fault) in the engine oil pressure control circuit, typically the wiring or solenoid that regulates a variable-displacement oil pump. The PCM monitors this circuit to maintain proper oil pressure for lubrication and variable valve timing. Because loss of oil pressure can quickly cause severe engine damage, this should be treated as urgent. Typical repair costs on Mercedes-Benz range from $700 to $2,200, depending on the specific model and root cause.
Common Causes of P06DA
- •Faulty oil pump control solenoid/valve
- •Open or shorted wiring in the control circuit
- •Corroded or loose solenoid connector
- •Low oil level or low oil pressure
- •Faulty oil pressure sensor
- •PCM control circuit fault
P06DA on Mercedes-Benz by Model
Mercedes-Benz GLA(1 issue)
- Variable Oil Pump Control Solenoid (Y130) Failure Inside Oil Pan - P06DA002015-2020
The M270 uses a two-stage variable-displacement oil pump whose output is switched by a PWM solenoid (Y130) mounted inside the oil pan, with its wiring harness routed through the pan and out an oil-tight connector. The solenoid winding fails open, or the in-pan harness insulation chafes, and the ME control unit sets P06DA00 - 'electrical fault / open circuit in the valve actuation of the engine oil pump.' The engine defaults to one pressure stage, so it usually still drives, but owners report an oil pressure or engine warning, a check engine light that returns immediately after clearing, and in some cases a low-oil-pressure red warning at hot idle. Because the valve lives inside the sump, the repair is far more invasive than the part cost suggests - on 4MATIC cars the front subframe and driveshaft have to come down to drop the pan.

What does P06DA mean on Mercedes-Benz?▼
P06DA stands for "Engine Oil Pressure Control Circuit/Open." This code indicates the engine computer detected an open circuit (or other fault) in the engine oil pressure control circuit, typically the wiring or solenoid that regulates a variable-displacement oil pump. The PCM monitors this circuit to maintain proper oil pressure for lubrication and variable valve timing. Because loss of oil pressure can quickly cause severe engine damage, this should be treated as urgent. On Mercedes-Benz specifically, this code is documented across 1 model.
What causes P06DA on Mercedes-Benz vehicles?▼
Common causes on Mercedes-Benz: Faulty oil pump control solenoid/valve, Open or shorted wiring in the control circuit, Corroded or loose solenoid connector, Low oil level or low oil pressure, Faulty oil pressure sensor. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P06DA on a Mercedes-Benz?▼
