P1449 MINI Code - Diagnostic Module Tank Leakage Pump Too High
Quick Answer
The evaporative system monitoring permits the detection of leaks in the evaporative system with a diameter of 0.02 inches and up. Common causes include Faulty Diagnostic Module Tank Leakage (DMTL) Pump, Diagnostic Module Tank Leakage Pump harness is open or shorted, Diagnostic Module Tank Leakage Pump circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1449 MINI Description
During the Reference Leak Measurement, the electrically actuated pump delivers through the reference restriction. The engine-management system measures the pump's electrical current consumption in this section.
During the Leak Measurement, the electrically actuated pump delivers through the charcoal canister into the fuel-tank system. The pressure in the evaporative system may be up to 2.5 kPa depending on the fuel level in the tank. The engine-management system measures the pump's electrical current consumption. A comparison of the currents of the reference leak measurement and the leak measurement is an indication of the leakage in the tank.
What are the Possible Causes of the DTC P1449 MINI?
- Faulty Diagnostic Module Tank Leakage (DMTL) Pump
- Diagnostic Module Tank Leakage Pump harness is open or shorted
- Diagnostic Module Tank Leakage Pump circuit poor electrical connection

Frequently Asked Questions about P1449 MINI Code
1. What does the OBDII code P1449 mean on a MINI?
P1449 indicates an issue with the Diagnostic Module Tank Leakage (DMTL) pump, specifically that its pressure is too high, signaling a potential problem in the evaporative emissions system.
2. What are the common symptoms of code P1449 in a MINI?
Typical symptoms include the check engine light turning on, potential fuel smell from the vehicle, and, in some cases, reduced fuel efficiency.
3. What causes the P1449 code to appear on a MINI?
Common causes include a faulty DMTL pump, clogged or damaged vent lines, a malfunctioning vent valve, or a wiring issue in the pump circuit.
4. Is it safe to drive with a P1449 code on a MINI?
While the vehicle may still be drivable, ignoring the code can lead to increased emissions and potential damage to the EVAP system. It's best to address the issue promptly.
5. How do you diagnose the P1449 code on a MINI?
Diagnosis involves scanning the vehicle with an OBDII tool, inspecting the DMTL pump, checking for clogged or damaged hoses, and testing the pump's electrical connections.
6. Can a loose gas cap trigger the P1449 code on a MINI?
While a loose or faulty gas cap can cause some EVAP-related codes, P1449 specifically points to an issue with the DMTL pump and is unlikely to be caused by the gas cap.
7. How can the P1449 code on a MINI be fixed?
Repairs may include replacing the DMTL pump, cleaning or replacing vent lines, repairing faulty wiring, or replacing a damaged vent valve.
8. How much does it cost to fix the P1449 code on a MINI?
The cost varies depending on the cause but typically ranges from $150 to $500, with DMTL pump replacement being one of the more expensive repairs.
9. Can the P1449 code clear itself on a MINI?
The code may temporarily clear if the issue is intermittent, but it will likely return until the underlying problem is resolved.
10. Does the P1449 code affect emissions testing?
Yes, a P1449 code indicates an EVAP system issue, which can cause the vehicle to fail an emissions test.
