P0183 on Volkswagen: Causes, Symptoms and Fix Cost
Quick Answer
Safe to drive (short-term)
P0183 on a Volkswagen means the signal from the fuel temperature sensor is higher than the control unit expects, which usually means an open circuit, a short to voltage or a failed sensor. The control unit uses fuel temperature to estimate fuel density and correct the amount injected. On many diesels the sensor sits in or near the fuel filter housing; on others it is on the fuel pump or rail.

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Volkswagen models that log P0183.
Volkswagen Golf TDI (common rail)
2009-2020
VW Group TDI engines label the fuel temperature sensor G81, and VCDS reports this fault as 16567/P0183, Fuel Temperature Sensor A (G81): Open or Short to Plus. Ross-Tech lists the fuse, then the wiring and connector, then the sensor. VW's own test watches the fuel temperature value while the connector is moved, which needs manufacturer-level software.
What causes P0183 on a Volkswagen?
Beyond the generic causes listed on the main P0183 page, these are the patterns noted for Volkswagen models:
Broken wire or loose connector at the G81 sensor
: Volkswagen Golf TDI (common rail)
Failed G81 fuel temperature sensor
: Volkswagen Golf TDI (common rail)
How to diagnose P0183 on a Volkswagen with OBD2
Follow these steps to pinpoint the root cause of P0183:
- Read the stored code and freeze frame with an OBD2 reader, and note whether other fuel codes (P0191, P0193) are stored too
- If your car reports fuel temperature to your reader (many do not on generic OBD2), check the value. A sensor that is unplugged or has a broken signal wire usually reads as the coldest possible value, such as minus 40 degrees
- Find the sensor for your engine (in the fuel filter housing, on the pump or on the rail, depending on the car) and inspect the connector for corrosion, bent pins or moisture
- With the sensor unplugged, a workshop checks the reference and signal circuits with a multimeter against the wiring diagram for a short to voltage or an open circuit
- If the wiring tests normal, replace the sensor, or the filter or pump module if the sensor is built into it
- Clear the code and road-test to confirm it does not return
