Description
This Mercedes used OEM part is an original OEM component. The primary OEM number is 321132, with alternative reference 10R-022251 also shown on the unit. It is a genuine used unit, removed from a running vehicle and tested before listing, and is offered as a direct original (OEM) replacement rather than an aftermarket copy.
It carries out the electronic control function it was built for in the vehicle. Because it is the original factory part, it fits, connects and communicates exactly like the unit that left the production line, so no changes to the wiring or the surrounding parts are needed. Fitting a matching original unit restores correct operation.
Common signs of a faulty unit include warning messages, lost functions, or fault codes linked to the system this part controls. Problems like these often start intermittently and then become permanent, and a diagnostic scan will usually store related fault codes pointing to this unit. Replacing it with a tested original such as this one clears faults caused by the part itself.
This is a used original part, removed from a running vehicle and tested before sale. Please match 321132 exactly against the number on your existing unit before ordering, as several similar units are used across the range and are not all interchangeable. Professional installation is recommended, and coding, programming or adaptation to the vehicle may be required after fitting depending on the equipment and configuration.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
