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: 155083, 1K6253609J, 1K6253609L, 220829 and 17 more.
