Code P2629 MINI Description
This function shall be triggered only if one of the following diagnosis is active (to set the readiness bit), which are 'Upstream Oxygen Sensor - Signal Monitoring During Fuel Cut-off' and 'Upstream Oxygen Sensor - Heater Monitoring'. The function shall go to the state = “active” only if one of the above diagnosis detected a fault.
If the sensor shows an augmented gain, i.e. the sensor signal is higher than the nominal characteristic line, the plausibility test during the fuel cutoff phase shall detect this symptom (signal voltage above e.g. 5,6 V *) during fuel cut off) and an Open Circuit is assigned to the line, Trim Current.
What are the Possible Causes of the DTC P2629 MINI?
- Faulty Upstream Oxygen Sensor Bank 2
- Upstream Oxygen Sensor Bank 2 harness is open or shorted
- Upstream Oxygen Sensor Bank 2 circuit poor electrical connection
How to Fix the DTC P2629 MINI?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P2629 MINI code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

1. What are the common symptoms of OBDII code P2629 in a MINI related to the upstream oxygen sensor open circuit monitoring trim current failure Bank 2?
The common symptoms may include poor fuel economy, rough idling, engine misfires, and the illumination of the check engine light.
2. What can cause the upstream oxygen sensor open circuit monitoring trim current failure Bank 2 code P2629 in a MINI?
Possible causes can include a faulty oxygen sensor, damaged wiring or connectors in the sensor circuit, exhaust leaks near the sensor, or issues with the engine control module (ECM).
3. How can I diagnose the upstream oxygen sensor open circuit monitoring trim current failure Bank 2 code P2629 in my MINI?
Diagnosis typically involves using an OBDII scanner to read the code, checking the oxygen sensor wiring and connections for damage, inspecting for exhaust leaks, and testing the sensor's functionality.
4. Can I drive my MINI with the P2629 code for the upstream oxygen sensor open circuit monitoring trim current failure Bank 2?
It is not recommended to drive with this code present, as it can lead to decreased fuel efficiency and potential damage to the catalytic converter over time.
5. How do I repair the upstream oxygen sensor open circuit monitoring trim current failure Bank 2 code P2629 in my MINI?
Repairing this code usually involves replacing the faulty oxygen sensor, repairing any damaged wiring or connectors, fixing exhaust leaks if present, and clearing the code with an OBDII scanner.
6. Are there any maintenance tips to prevent OBDII code P2629 in a MINI related to the upstream oxygen sensor?
Regularly inspecting and maintaining the oxygen sensor, ensuring the exhaust system is in good condition, and using high-quality fuel can help prevent issues leading to this code.
7. Can a DIY enthusiast fix the upstream oxygen sensor open circuit monitoring trim current failure Bank 2 code P2629 in a MINI?
Depending on your skill level and access to tools, some DIY enthusiasts may be able to replace the oxygen sensor and perform basic troubleshooting steps, but complex issues may require professional help.
8. How long does it typically take to repair the OBDII code P2629 in a MINI for the upstream oxygen sensor open circuit monitoring trim current failure Bank 2?
The repair time can vary based on the exact cause of the issue and the availability of parts, but it generally takes a few hours to replace an oxygen sensor and address related issues.
9. Will resetting the ECU clear the P2629 code for the upstream oxygen sensor open circuit monitoring trim current failure Bank 2 in my MINI?
Resetting the ECU may temporarily clear the code, but if the underlying issue is not fixed, the code is likely to return after driving the vehicle and the ECM performs its diagnostic checks.
10. Is it necessary to take my MINI to a dealership for OBDII code P2629 related to the upstream oxygen sensor open circuit monitoring trim current failure Bank 2?
While a dealership can provide specialized expertise, an independent mechanic with experience in MINI vehicles can also effectively diagnose and repair the issue, potentially at a lower cost.
