Special Features

  • Specs & OE/Cross-Ref — 12-volt, 4-pin, normally-open (main current) relay; direct replacement for 0025428819 / A0025428819 / 002-542-88-19; cross-references include HELLA 4RA 007 793-031 / 4RA007793-11 and equivalents where used. Match by OE number and 4-pin layout before purchase.
  • Install & Location — Plug-in blade relay typically located in the engine-bay or interior fuse/relay box; used by circuits such as accessory power and (on certain trims) the secondary air injection pump. Always compare cavity assignment to your fuse-box diagram and confirm the socket footprint.
  • Compatibility by Platform (verify by OE) — Compatible with Mercedes-Benz platforms where specified: W205 (C-Class), W213 (E-Class), W222 (S-Class), X253 (GLC-Class), W156/X156 (GLA-Class), W246/W242 (B-Class), W447 (Vito/V-Class), W117/X117 (CLA-Class), W172/R172 (SLK/SLC), W231/R231 (SL-Class), W166/X166 (ML/GL/GLE/GLS). Use OE number A0025428819 to confirm fit for your exact year/trim.
  • Later-Model Coverage (examples) — Also seen on select later models (usage varies by trim and option content), e.g., AMG GT 53, CLS450, E350 in the 2021–2022 model years where equipped. Always validate by OE and relay position in your specific fuse map.
  • Helpful Complements (for related searches; sold separately) — Depending on model, customers often replace or check related items together: A0025428719 (companion 4-pin relay used in adjacent cavities on some platforms), and common MB relay part families like A0009828523 / A0009828323 / A0009828223 (use only if your fuse-box diagram calls them out). Match strictly by OE and socket assignment.
