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.

Hello - I just bought a 2004 Jetta - day one - mil light came on. Car runs fine. What could it be? 2 mechanics checked the car over before I bought it and carfax said it was one owner no problems.


Have VW check it out. I had just got my 04 GLI with 70,000 miles when the light came on. The thermostat triggered the light and so I had the whole timing belt, thermostat, and water pump service. Worth the money.

VW Jetta 2003 1.9 TDI trunk does not want to open with remote My Jetta trunk recently started to give me problems without warning. I cannot get the trunk open with the remote. The trunk only opens manually...


If your lock actuator engages (you can hear the sound it makes) with the remote/electric button on the door, but the trunk doesn't open then the problem is likely a broken plastic arm that the electric assembly pushes. You can see it if you unscrew the inside cover from the trunk lid and try the remote. I started having the same issue with VW Jetta 2002 GLS that was rear-ended 8 months ago. My guess is the cracked plastic finally gave out in the cold weather.
