1998 VW Jetta Wolfsburg P0442 EVAP - Please let me know what check engine code P0442 for my 1998 Jetta Wolfsburg means. My husband was driving my precious Jetta Wolfsburg, went over some bumpy railroad tracks and the check engine light came on.

2007 VW EOSQuestion: P008B on a VW 2007 EOS. the chk eng light is on. 2.0T engine 13,000 - Robert, December 2008

Answer: Hi Robert. The description is Low Pressure Fuel System Pressure - Too High. I'm not familiar with that P008B code. A quick Internet search on P008B and P0008B brought up the following responses: "I threw the same code on my GLI, completely stock. Got the code from Autozone but they didnt have a definition for it so I took it to the dealer. They didnt give me a straight answer, but they said the part is responsible for fuel pressure/delivery. Said if it wasnt replaced the car might not start." and "Mine read P008B using a ScanGauge. Took it to the dealer and they replaced a bad fuel sensor and a new CL software update.". I recommend you get your hands on a VAG-COM tool or let the dealer tackle the job. Being a 2007 with average mileage I would think it's under warranty. If it is, just let the dealer fix it and forget about it ;-) Good luck!

2002 Volkswagen Jetta TDIQuestion: My 2002 Jetta tdi has a check engine light on. I have a scanner that tells me the trouble code is 00673. Can you tell me what that is? - John, December 2008

Answer: Hi John. The code 00673 doesn't mean a thing to me. Is it possible it's a P0673 code? What scanner are you using? A P0673 code means Cylinder 3 Glow Plug Circuit/Open. If that is the code, I'm simply going to refer you to this EXCELLENT thread on that code at Good luck!

2003 VW JettaQuestion: I have a 2003 Volkswagen Jetta (50k). My Check Engine light came on. I took it to Autozone and got a P2181 code (Cooling System Performance). My engine temperature is normal. Could it be the water pump even though the temperature is normal. - Cody, October 2008

Answer: Hi Cody. Please see the answer below this one (2003 Passat). Yes, it could possibly be the water pump, but it could be other things as well. Good luck!

2003 VW Passat Engine LightQuestion: I have a 2003 passat with the 1.8T engine. I have a check engine light with a p2181 code. I know it's coolant related. Can I get anymore details? - Dave, September 2008

Answer: Hi Dave. Yes, the VW P2181 code description is Cooling System Performance. Possible causes include (but are not limited to) a bad coolant temperature sensor (CTS), stuck thermostat, bad waterpump, bad electrical connector somewhere between the CTS & the ECU (car's "brain"), or a failed cooling fan. Most likely the problem is the coolant temperature sensor, I've seen that before. Anyway, start by checking the sensor and replacing if necessary... go from there. Good luck!

2003 VW Jetta GLQuestion: Check engine light on for 2003 Volkswagon Jetta GL. Mileage 72000 Where can I find the trouble code. Is there a place that can get me the code for nothing? - Vincent, September 2008

Answer: Hi Vincent, thanks for your question. Yes, there are places that will read the code for free. If you take your car to an AutoZone near you, they'll read the code(s) for free. Other auto parts stores may do it as well, just call and ask.

Once you have the code, you can look up generic P0xxx powertrain codes on the home page here, or visit [VW trouble codes] for VW-specific P1xxx powertrain code descriptions. Keep in mind the parts store is in the business of selling parts so do your homework before buying parts. Get the trouble code & description, do an Internet search to research the code. You don't always have to replace parts to fix a trouble code. If at some point you want to buy a code reader, the VAG-COM unit by Ross-Tech is a good choice for VW vehicles. Good luck!
