WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

Information

The two senders have different shapes and may not be switched.
The float installed in the left direction of travel is flat, while the float installed in the right direction of travel is spherical.
The removal of both senders is explained in parallel in this description. If only one sender has to be removed, the other side of the tank can remain untouched .

Information

The effect of fuel and various tolerances means that the left fuel level sensor can become jammed under fuel lines or the sensor's electric cable. The instrument cluster would then display an incorrect fuel level.

To prevent this, the two fuel lines coming from the left pump and the electric cable should be tied together with a tie-wrap following repairs.
