I have a 2002 vw Jetta wagon. The variable vehicle speed sensor is bad and the check engine light comes on because of it. Is this an easy fix ?


Please provide the fault code. It will need to be in standard format for OBD2 systems, not VW codes. The codes are in this format PXXXX, the X being numbers.

2002 VW Golf TDI - Live in northern ontario - -20's with wind chill. When I first drove the car this morning - error code (looks like a clock) on upper right portion of speedometer gauge. Just flashes on ...


Classic 109 relay failure.

Relay is for the Glow Plug system.

This relay provides the power to all of a TDI's engine-based electronics.

If the glow plug light comes on intermittently by itself, check your brake lights too.

A burned-out bulb will cause the glow plug indicator light to come on. Sometimes flashing is caused by a bad Brake Lamp Switch on the Brake Pedal. It was updated for free by VW .

If you can see it under the knee panel, the Brake Lamp Switch body should be Metallic Green....if it is Purple or Black it need updated.

What are the cause of a mil light on 2002 vw jetta- how cna one diagnosi this under the hood? can cold weather be a cause and can this correct itslef


Check the MIL code to see what exactly is the problem. For instance, it may be an O2 sensor that has been damaged in the cold.
Please read the following link. It is a great source to troubleshoot MIL codes.

Volkswagen Diagnostic Trouble Codes
DTC Table - General

From model year 1996, vehicles manufactured for the North American market are equipped with a Government required diagnostic system known as On-Board Diagnostics II (OBD II). This system monitors operation and function of all engine management system activity and automatic transmission operation to insure compliance with specified emission levels.

Vehicle emission levels are constantly monitored by the OBD II system and malfunctions are recognized and recorded. A Malfunction Indicator Light (MIL) in the instrument cluster alerts the driver to the fault and the need to have the system checked for fault codes. These codes follow a standard format and are known as Diagnostic Trouble Codes (DTCs).

DTCs are assigned two codes. The first code is a numerical code assigned by the factory. The second code is referred to as a P-code and follows a structure required by law and defined by the Society of Automotive Engineers (SAE). This standard uses a letter to designate the system and four numbers to further identify and detail the malfunction as listed below.
