057115540 Audi JET

This little guy’s job is pretty specific. It regulates the flow of exhaust gases back into the engine's intake. Think of it as a precisely controlled leak. It doesn’t just open and close; it meters the amount of exhaust gas recirculated. It uses engine vacuum to operate a diaphragm which then controls a small valve opening. It’s part of your Exhaust Gas Recirculation system – the EGR. The EGR system’s main goal is to lower emissions and improve fuel economy. The jet valve is a key component in how that system works. It helps to fine – tune the amount of exhaust gas being reintroduced. It’s usually found on older engines, mostly diesels, and is often a part of the EGR cooler assembly. If this valve fails, it can really mess things up. You’ll likely notice rough idling, poor fuel economy, and possibly even a check engine light. A stuck – open valve will cause too much exhaust gas to enter the intake, leading to misfires and reduced power. A stuck – closed valve won't let enough exhaust in, and you’ll probably fail an emissions test. It’s one of those parts that, when it's working right, you don't even think about. But when it goes bad, you’ll notice it pretty quickly. We carry a good selection of these, and you can find them easily enough on Fixparts Online if you prefer to look yourself. It’s a relatively inexpensive fix compared to some other engine issues, so addressing it quickly is a good idea. Smart investment: Jet Valve (MPN 057115540) comes with a 12-month warranty!
