Does this fit my car?

It is a specific-fit downstream sensor for the listed Audi A4 Quattro, Audi TT Quattro, Porsche Cayenne, VW Golf, Jetta, Beetle, Golf City, Jetta City and R32 applications. Check your model, engine and sensor position before ordering.

Is it a direct replacement?

Yes. It uses the factory-style connector and threaded mount, so no splicing or adapter is needed on listed applications.

How is it different from a universal sensor?

A universal sensor needs its old connector cut off and rewired. This one is built to the original dimensions and plugs straight in.

What does it cross-reference?

It cross-references Bosch 16034 and NTK 25604 for the same applications, so either can serve as an alternative.

Will it fix my check-engine light?

It fixes codes caused by a worn downstream sensor. If the light returns, the cause may be wiring or the catalytic converter instead.

The sensor with its 4-wire harness and male connector. A sensor socket is not included.

What reviewers say

Owners of these VW, Audi and Porsche applications generally report the DENSO 234-4808 fits and plugs in like the original and clears downstream oxygen-sensor codes. Complaints are uncommon and tend to involve codes that return when another fault, such as wiring or the catalytic converter, is the real cause.

What people mention

FitPraisedOwners say the threads and connector match the factory part and it installs without adapters.
Code fixPraisedMany report the downstream oxygen-sensor check-engine light stays off after replacement.
SignalPraisedDrivers note stable fuel trims and readings once the new sensor is in.

About the DENSO 234-4808 Oxygen Sensor

The DENSO 234-4808 is an OE Style heated oxygen sensor for downstream positions. It is a specific-fit replacement for select Audi, Volkswagen, and Porsche vehicles. It monitors the exhaust to support engine management and fuel control.

The sensor is built to match original equipment dimensions and connection points. It has a threaded mount, a 4-wire design, and a male connector. An aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination.

Before installing, confirm the connector style, wire count, thread diameter, and downstream position. Inspect the exhaust bung threads and the sensor connector. Route the harness along the vehicle's original path, away from heat and moving components.
