Having trouble starting your old VW or Audi diesel when it's cold? This glow plug relay is a key part for 1977-1992 models with the 1.6L L4 diesel engine. It fits a ton of vehicles: Volkswagen Golf, Jetta, Rabbit, Vanagon, Pickup, and Audi 4000, 5000, Dasher, Quantum, etc. The relay controls the glow plugs, heating them up so the engine fires up smoothly. This is a direct replacement made to OEM specs (or better) with durable materials. It's been tested for reliability, so you can count on it. Pretty straightforward to swap out if you're handy – just disconnect the battery first. Get your classic diesel starting like it should, even on chilly mornings.
