About this product
When alternator regulator performance matters, the BOSCH 1 986 AE0 056 delivers — built to the same dimensional and material standards as the original part it replaces. Compatible with VW vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 03G903097, 059 903 803 F, F 00M 346 044, F 00M 346 092 and 1 more. Matching these numbers confirms a like-for-like replacement with no loss of function. BOSCH 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.
