Primary Authorized Stockist & Sensor DistributorMahindra BS6 DEF Urea Tank Assembly 0906AAB00261N
The Mahindra DEF Urea Tank Assembly price 0906AAB00261N is an OEM Diesel Exhaust Fluid (DEF) tank assembly used in the BS6 SCR emission control system of selected Mahindra diesel vehicles. It is commonly referred to as a Mahindra urea tank, DEF tank, AdBlue tank, Diesel Exhaust Fluid tank, urea solution tank or SCR tank.
The DEF tank stores the Diesel Exhaust Fluid/AdBlue/urea solution required by the vehicle's Selective Catalytic Reduction (SCR) system. DEF is injected into the exhaust system, where it helps reduce harmful nitrogen oxide (NOx) emissions and allows the vehicle's BS6 emission system to operate correctly.

Common Problems Caused by a Faulty DEF/Urea Tank
A damaged or malfunctioning DEF tank assembly can cause problems in the vehicle's SCR after-treatment system.
Common symptoms may include:
- DEF/AdBlue warning light on the dashboard
- Urea warning message
- Check Engine/MIL warning
- SCR system warning
- DEF level showing incorrectly
- DEF level remaining empty even after filling
- Incorrect DEF/urea level reading
- DEF system malfunction warning
- Urea system fault
- SCR efficiency-related warning
- Engine performance limitation
- Reduced power or limp mode
- Countdown to no-start condition
- AdBlue/DEF system unable to operate correctly
- Difficulty starting after an SCR/DEF fault
- DEF leakage around the tank
- Damaged or cracked urea tank
- Contaminated or crystallized DEF
- Communication faults between DEF components and ECU
Common DEF/Urea Tank Fault Codes
Fault codes depend on the exact Mahindra vehicle, ECU, SCR system and failed component. A DEF tank problem can be associated with faults relating to DEF level, DEF temperature, DEF quality, DEF pressure, tank sensor, wiring, communication or SCR operation.
Possible diagnostic fault-code categories include:
- DEF/urea level sensor fault
- DEF temperature sensor fault
- DEF quality sensor fault
- DEF pressure fault
- DEF tank sensor circuit fault
- DEF tank communication fault
- SCR system fault
- NOx/SCR efficiency fault
- Urea dosing system fault
- DEF supply system fault
- CAN communication fault
Important: A fault code should not automatically be interpreted as a defective DEF tank. The complete SCR system should be diagnosed before replacing the tank assembly.
Causes of Mahindra DEF Tank Problems
Some common causes include:
1. Damaged DEF/urea tank – Physical damage or cracks can cause DEF leakage.
2. DEF contamination – Diesel, water, dirt or other fluids entering the DEF tank can damage the SCR system.
3. Incorrect DEF/urea fluid – Only the correct specification of Diesel Exhaust Fluid should be used.
4. DEF crystallization – Dried DEF can form crystals around connections and components.
5. Faulty tank sensor – A defective level, temperature or quality sensing system can result in incorrect readings.
6. Electrical wiring problem – Damaged wiring, loose connectors, corrosion or poor electrical connections can create sensor faults.
7. CAN communication issue – Communication problems between SCR components and the ECU can trigger warning messages.
8. Frozen DEF – DEF can freeze at approximately -11°C, although the vehicle's DEF system is designed to manage this condition.
9. SCR component failure – The problem may actually be related to the DEF pump, dosing module, NOx sensor, wiring or ECU rather than the tank itself.
Diagnosis and Solution
Before replacing the Mahindra DEF urea tank 0906AAB00261N, perform a complete diagnostic scan using suitable diagnostic equipment.
Step 1 – Scan the ECU
Read the stored and active DTC/fault codes from the engine and SCR/after-treatment system.
Step 2 – Check DEF Level
Check whether the DEF level displayed by the vehicle corresponds with the actual quantity in the tank.
Step 3 – Inspect the Tank
Look for:
- Cracks
- Leakage
- Physical damage
- DEF crystallization
- Damaged connectors
- Damaged pipes and hoses
Step 4 – Check Wiring and Connectors
Inspect the tank sensor wiring, connectors, power supply, ground and CAN communication lines for damage, corrosion or loose connections.
Step 5 – Check DEF Quality
Contaminated or incorrect DEF can cause SCR system problems. If contamination is suspected, the system should be inspected and serviced according to the manufacturer's procedure.
Step 6 – Check Related SCR Components
Do not replace the DEF tank without checking other components such as:
- DEF/urea pump
- Dosing module / urea injector
- NOx sensors
- DEF pressure system
- DEF temperature/level sensing system
- SCR catalyst
- ECU/ECM
- Wiring harness
- CAN communication
Step 7 – Replace the Tank if Confirmed Faulty
If diagnosis confirms that the DEF tank assembly is damaged or its integrated sensing components have failed, replacement with the correct OEM-compatible Mahindra DEF tank 0906AAB00261N may be required.
After replacement, the vehicle may require diagnostic calibration, component replacement programming, DTC clearing or SCR system reset, depending on the vehicle configuration.
Why Does the Mahindra BS6 DEF Warning Come On?
A DEF warning does not always mean that the urea tank is empty. The warning can be triggered by low DEF level, incorrect DEF quality, tank sensor problems, DEF pressure problems, dosing problems, NOx sensor faults, wiring issues or other SCR system faults.
Therefore, the correct approach is to scan the vehicle, identify the DTC and diagnose the complete DEF/SCR system before replacing any component.
Why Is the DEF Level Not Increasing After Filling?
If the DEF tank has been filled but the dashboard still shows low or empty DEF, possible causes include a DEF level sensor fault, tank sensing problem, wiring/connector issue, incorrect fluid detection or ECU/SCR communication problem.
A diagnostic scan and live-data inspection can help identify the cause.
