Is it safe to drive with this code?

Driving with P006E is often possible in the short term, especially if the vehicle has entered limp mode to protect the engine, but continued driving risks poor fuel economy, further electrical damage, and potential harm to internal engine components if boost control remains unregulated—see our full disclaimer for professional advice.

P006E may affect your MOT result if the malfunction indicator lamp (check engine light) is illuminated at the time of the test; what ultimately matters is whether the MIL is on during inspection—refer to our disclaimer for MOT-specific guidance.

Roughly how much does it cost to fix?

Repair costs vary widely depending on the root cause: if it is a simple wiring repair or connector clean, expect low two-figure to low three-figure costs; replacing a boost control solenoid typically falls into the low to mid three-figure range; more complex turbocharger or ECM faults can reach high three-figure or even four-figure sums, particularly at main dealers versus independent garages.

Can this code appear on non-turbocharged cars?

Occasionally P006E can be logged on vehicles without a turbocharger or supercharger if the ECM still monitors a boost control circuit, though in such cases the fault often points to incorrect wiring, a phantom sensor reference, or a software glitch rather than an actual forced-induction problem.

P006E

Powertrain

Turbocharger/Supercharger Boost Control A Supply Voltage Circuit Low

The engine control module has detected that the electrical supply voltage to the turbocharger or supercharger boost control solenoid is lower than the expected range, typically indicating a wiring or power-supply issue in the forced-induction system.

ⓘ Information only. This page provides general educational information about fault code P006E. We do not assess the urgency or safety implications of any specific fault. That requires in-person diagnosis by a qualified mechanic. Full terms.

Recommended next steps

Whether a fault is urgent, drivable, or routine depends entirely on the cause on a specific vehicle, and that can only be determined by a qualified mechanic with diagnostic equipment. If a warning light is illuminated, the most reliable next step is professional diagnosis.

What does P006E mean?

P006E is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Turbocharger/Supercharger Boost Control A Supply Voltage Circuit Low.

This is a standardised OBD-II code. The technical definition is the same regardless of the make or model of vehicle, although specific causes and symptoms can vary between vehicles.

About Turbo / Supercharger codes

Turbo codes report faults in boost pressure, variable-vane mechanisms, wastegates, or boost sensors. On EU diesels, sticking variable vanes from carbon buildup are extremely common at higher mileages.

What we know about P006E specifically

We record the SAE J2012 standardised definition and the system this code belongs to, but we have not yet published detailed driver-reported symptoms, common causes, or step-by-step diagnostic guidance for P006E.

Rather than invent that information by generating generic content from a template, we leave it out. For specific guidance, the most reliable sources are:

•your vehicle's own service manual or manufacturer-specific technical bulletins
•a qualified mechanic with a manufacturer-level diagnostic tool
•a marque specialist familiar with your make and model
