What is Mahindra part 1805AAA01271N?
On a multiplexed vehicle, the body module sits between the switches and the body electrical loads. Workshops usually look at it when several unrelated body functions go wrong at once.
It is a sealed unit with four connectors. J1 and J2 are the two high-density headers; J3 and J4 are the others.
Which Mahindra models does 1805AAA01271N fit?
Our 1805AAA01271N part page lists it for: XUV500 W3, XUV500 W4, XUV500 export specification.
Check with your VIN before ordering for: XUV500 W6, W8, W10 (may use a different module number).
When should a workshop suspect the MBFM?
- Several unrelated body electrical functions misbehave at the same time.
- Faults return after wiring and fuses have been checked.
- If the problem is how the engine runs, the MBFM is probably not the part: the engine ECU is a different unit.
How do you confirm 1805AAA01271N is the right part?
- Read the label: 1805AAA01271N, top left.
- Check the marking: MBFM-201 W3/W4/All Exp.
- Check Delphi number: Delphi P/N 28484577 and serial starting 28484577.
- Send VIN: We match it to Mahindra's catalogue.
The number is written both as 1805AAA01271N and 1805AAA01271. Both refer to the same part.
Fitting notes for workshops
- Read the label first. Modules that look the same can carry different part numbers. Read the white label on the old unit.
- Coding. Body modules are often configured to the vehicle. Plan for dealer-level coding unless we confirm otherwise for your market.
- Higher trims differ. W6, W8 and W10 vehicles can use different body module numbers: send us the number from your unit.
