New, unused vacuum check valve for VW, Audi, Škoda and Seat group vehicles. Catalogue number: 058 905 291 K 058905291K – also fits as a replacement for older revisions 058905291B. Most common symptoms of failure: This one-way valve prevents loss of pressure in the vacuum system. When the internal rubber diaphragm fails, the valve leaks in both directions or blocks completely, which leads to: Hard brake pedal (especially in the morning before starting the engine or right after switching off the car). Rough idle and engine "stumbling" because the computer registers false air. Fault codes related to the EVAP system or secondary air injection (SAI). Most often used on the legendary 1.8 Turbo engines (AGU, AUM, AUQ, BAM, APU, AWT...), as well as on some VAG petrol and older-generation diesel engines. Immediately available, no waiting for import or ordering while your car is off the road. Quick and easy replacement in 5 minutes. Before ordering, compare your part with the part in the photos and/or consult your mechanic. NEW!
