7P0919673K Fuel Tank Sender Unit For Volkswagen Touareg 7P 2011-2017

7P0919673K in-tank fuel level sender for Volkswagen Touareg 7P, the second generation introduced for the 2011 to 2017 model years. It reports tank contents to the instrument cluster and works alongside the low fuel switch contact that triggers the warning lamp.

Construction follows the VW group pattern for the 7P platform: a polyamide carrier with two locating tabs, a float on a stainless wire arm, and a ceramic substrate carrying a laser trimmed resistive track. The wiper is a twin contact design, so a single worn finger does not produce an open circuit, which is why these units tend to drift slowly rather than fail outright. A moulded seal groove takes the flange O-ring, and the electrical side uses a sealed four pin housing with a secondary lock on the terminal carrier.

The sender sits in the tank under the rear seat on the right hand side of the vehicle and can be changed without dropping the tank. Release the seat cushion, remove the access plate, unplug the connector, then undo the plastic locking ring. Clean the tank flange before the new O-ring goes in, because grit under the seal is the most common cause of a smell of fuel after a sender change. Do not twist the arm to make it fit, and do not operate the sender out of the tank for longer than needed.

Reported faults include a gauge that reads full for the first hundred kilometres after filling and then falls quickly, a needle that swings while braking, and a distance to empty figure that recalculates in large steps. On the 7P Touareg the sender signal also feeds the auxiliary heater logic, so a failed unit can stop the parking heater from running even when the tank is half full.

Each unit is checked for resistance at the empty, quarter, half, three quarter and full positions. Supplied with the flange O-ring.
