Got the above fault code does anybody know what it is?
I know it is knock control control module malfuction, but what is that???

My search came up with an Evap system problem with the fuel level sensor but I could not find VW specific procedure here at home to suggest a course of action. I'll ask at the office tomorrow.

DIAGNOSTIC TROUBLE CODE (DTC) - P0462 FUEL LEVEL SENSOR LOW VOLTAGE

Details of the Circuit

· Using inputs of fuel level from the Fuel Level Sensor, the engine control module (ECM) calculates existing vapor pressures within the fuel system.

· With varying fuel content vapor pressure shows a marked change.

· To ensure proper functioning of evaporative emission (EVAP) system, it is imperative to calculate Vapor Pressure.

· Fuel Level helps to gauge whether it is capable of detecting extremities of existing EVAP system faults accurately.

· This Diagnostic Trouble Code (DTC) detects a stuck fuel level sender.

Pre-requisites of Setting the DTC

· Fuel Level Sensor voltage < 0.05V.

· Fuel Level Sensor circuit low voltage.

What happens when DTC sets?


When will DTC clear?

1) The Malfunction Indicator Lamp (MIL) will not glow


1) A history DTC will be removed after 40 successive warm-up cycles without any fault

2) The ECM will store the previously recorded conditions of the DTC as Failure Records data only.

2) DTC(s) can be cleared using the scan tool

3) This information will not be stored in the Freeze Frame data.

Found this thought it might point you in right direction?, also look at bba-reman for some sort of check list process,
