Verified to fit AUDI models. All compatibility data is cross-checked against the TecDoc database — select your vehicle to confirm the part matches your specific engine and year. This part supersedes original equipment references: 431819031, 431819031A, 431819031B, 443.819.030 and 5 more. Matching these numbers confirms a like-for-like replacement with no loss of function. HART is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops.
