Mercedes Actros MP4 headlamp switches: three 8P records
SAP-B204, B204A and B204B share an 8P note and Actros/MP4 catalog reference, but not the same OE list.
A buyer may receive three apparently plausible quotations for an Actros MP4 headlamp switch. The SHIRE catalog lists B204 with 9605452804/9605454604, B204A with 9605452504/9605454304 and B204B with 9605452604/9605454404. All say 8P. That is enough to prevent an OE-blind purchase, not enough to certify a substitute.
Keep each OE pair attached to its SKU
A comparison worksheet should have separate lines for all proposed records. Ask which exact marking the seller can supply. Merging six OEs under one generic “MP4 8P” entry hides the decision a buyer needs to make.
Compare the switch as a complete assembly
Request button-symbol, rear-plug, mounting and label images. If a technical drawing or trusted original-part record is available, use it to confirm the required version. Eight pins alone do not establish control logic.
Approve and receive by version
Use the accepted SKU, OE and evidence reference in the quotation and carton labels. Any revised offer should be a new candidate for approval, not an edit that overwrites the requested number.
Purchasing guidance, not installation or diagnostic instructions. Confirm compatibility and specifications with the supplier and a qualified technician.
