Fuel Temperature Sensor for 1998-2003 TDI
This is the stock Bosch TDI fuel temperature sensor for all 1996-2003 TDI vehicles in the US and Canada.It also fits all VE type injection pumps worldwide. It has a VW part number of 028 906 040C. Also known as the G81, this sensor has a direct effect on start of injection. A bad sensor can make your TDI injection timing unstable. Replacement of this sensor requires the Metalnerd MN3001 triangular socket which we available for $23.00. Also required is the top quantity adjuster seal which is contained in the Bosch Injection Pump Seal Kit also listed in this section. A Torx T10 screwdriver or socket is required to remove the screws holding the fuel temperature sensor to the quantity adjuster. For those of you who are sticklers for details, the torque spec for the 6mm Quantity Adjuster top cap screws is 7-10 Newton Meters. Gutenteit works, too. Just remember that you are tightening steel screws into an aluminum pump body.
