If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

I have a 2008 volkswagen jetta that has 9500 miles on it. this morning there is a yellow light on that resembles an engine? I think it is suppose to be an outline of an engine


Engine trouble or service light. Could just be wanting an oil change, maybe something more. Is it running OK? Check owners manual for details about the light. You are probably still under warranty anyway, check with VW dealer. It may not cost you anything to fix.

2001 VW Jetta GL TDI will not start. I checked the battery, and it is fine. Engine turns over when I turn the key, but it seems like no fuel is getting to the engine.


If you have blue/grey smoke coming out of the tailpipe, you are getting fuel, you can also check to see fuel if you pull back the braided cover on the fuel line (left front side of engine compartment). If you see smoke, check the glow plug relay (180) under the dash.

The brake lights (all 3) on my VW Sharan do not work although there is an intermittent flashing. At the same time the Glo Plug light is flashing. what is the cure?


There is a recall on the brake light switch. VW should replace it for free.

-----------------------------------------------------------------
Defective brake lights on Golf, GTI, Jetta, New Beetle and R32 are a potential safety hazard and should be replaced. February 26, 2007 - NEW YORK (CNNMoney.com) -- Around 800,000 Volkswagen vehicles have been recalled Monday because of faulty brake lights, the National Highway Traffic Safety Administration said.
The 790,000 vehicles include Jettas, New Beetles, Golfs, GTIs and R32s...all in the United States.
The specific years and models affected are:
  • 1999-2005 Jetta sedans
  • 2001-2005 Jetta wagons
  • 1998-2007 New Beetle
  • 2003-2007 New Beetle Convertibles
  • 1999-2006 Golfs and GTIs
  • 2004 R32
The malfunctioning brake lights and brake light switches could fail to come on or remain stuck on.
This recall expands on one announced by Europe's No. 1 carmaker last year, when 362,000 Jettas and New Beetles were recalled due to the same defective part.
Volkswagen said that dealers will immediately be prepared to accept service appointments to perform the repair at no charge, but the notification process isn't scheduled to begin until April.
NHTSA did not say if any injuries had been reported linked to the defective brake lights.

The ABS light comes on but it doesn't seem to


The simple DIY method is to gently hose down each wheels when they are COMPLETELY COLD.
Dirt can cover to ABS sensors.

Most failure are from the front wheels because of the heat.

The car wash with under side cleaning will also do the trick if it's a dirt related problem.

Remove the negitive battery cable or clear the OBD-II code.

MAC and OTC make ABS senor tester to pin point the trouble spot but it cost $$$.

Do the preventive cleaning before bring it to the shop.


Please post more information after you clean out the wheel sensors.

2001 vw jetta gs :check engine light goes on and off


sounds like a faulty sensor tripping and reconnecting.. the next time the light comes on, take it to an advance auto store or an auto zone, they can read your codes for free... this will tell you what is being tripped, that way you know exactly what you need to get checked and/or fixed instead of a mechanic poking around trying to find everything thats NOT wrong. but if you are not expeiriencing any difficulty with the car, you should be fine. the check engine light actually means alot less than most people think. its usually a transmission or emissions sensor, or even as simple as leaving your gas cap off after filling and then driving for awhile.
