BMW 244C00: Meaning, Symptoms, Diagnosis and Fix
Understand BMW 244C00, its common symptoms and causes, and how to diagnose it methodically with OBDThink before replacing parts.
— Tekin Code
BMW code 244C00 concerns charge-air pressure control. It tells you where to begin, not which part to replace. Read the complete vehicle scan and confirm the engine, model and control module before acting.
What Does 244C00 Mean?
The responsible module has detected the DDE sees actual charge-air pressure below the requested value, described as positive control deviation. The exact wording and test conditions can vary by VIN, engine and module software, so verify the description against your vehicle.
Code: 244C00
System: charge-air pressure control
Definition: the DDE sees actual charge-air pressure below the requested value, described as positive control deviation
Variation: confirm by VIN, engine and control-module software
Treat this code as a diagnostic direction rather than proof of a failed component. Intermittent voltage, wiring or operating conditions can leave a stored history code.
Possible Symptoms
• Drivetrain warning or limp mode
• Weak acceleration and delayed boost
• Whistling, hissing or intermittent power loss
Possible Causes
The code identifies the detected condition, not its root cause. Separate an electrical or sensor fault from a genuine mechanical problem before buying parts.
• Loose charge-air hose or damaged seal
• Split boost pipe or leaking intercooler
• Faulty MAP sensor or wiring
• Vacuum leak, pressure converter or turbo actuator fault on applicable engines
• Restricted intake, EGR or DPF; worn turbocharger or engine fault
Diagnosis with OBDThink
OBDThink is an independent BMW diagnostic and coding mobile app and is not affiliated with BMW AG. Use it to scan the relevant modules, save the DTC and freeze frame where available, and compare related data.
• 1. Run a complete vehicle scan and record all related codes and freeze frame data.
• 2. Inspect the relevant connectors, wiring, grounds, hoses and visible components.
• 3. Compare commanded and actual data under the conditions in which the fault appears.
• 4. Test the suspected circuit or component with the correct service information.
• 5. Clear the code only after repair, then reproduce the original operating conditions.

The code identifies the detected condition, not its root cause. Separate an electrical or sensor fault from a genuine mechanical problem before buying parts.
Solutions
• Low — secure a hose or replace a verified seal
• Medium — repair a leaking pipe, intercooler, vacuum line or sensor circuit
• Medium — service a proven control-solenoid or actuator issue
• High — repair restriction or replace a turbocharger only after complete testing
After the repair, clear the DTC, repeat the conditions that originally set it and run a complete scan. The repair is verified only if the code stays absent and operation is normal.
Is It Safe to Drive?
Drive only if the vehicle remains predictable and no red warning, overheating, smoke, severe noise or major power loss is present. Otherwise stop safely and arrange professional recovery.
A careful scan, visual inspection and step-by-step testing usually solve 244C00 more reliably than guessing. Start with the inexpensive checks and escalate only when the evidence supports it.
