I also have a 1999 VX passat GLX. I had the same problem last year and had it repaired. It was around $1,000 in the Chicagoland area.
Good Luck

The flashing is telling you that the engine is mis-firing, the dealer will run a test to determine the cylinder that is mis-firing, chances are it is something simple

SOURCE: 2007 Passat wagon. I need to reset the air bag warning light.

the air bag light will only show if the ignition was turned on while it was disconnected.

it will defo need to be pluged into the computer to be put out but some smaller garages will have the software to do this and will be a little cheaper.here in ireland VW wanted 50euro to do mine but a small garage done it for 30euro.

you can buy code finders/reset gadgets on ebay but might not be worth it for one job compared to $130.

my suggestion would be to get the main dealer to do it if a normal automotive shop cannot access it.

Read the owners manual or call the V.W. service department. sound like you need to clean the filter. If you ignore the warning more then 3x you will cause damage and it will be costly.

Emissions warning light iluminated


Hello read and understand why.
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

There may be no check engine light but that doesn't mean there isn't a code in the ECU. Especially with a misfire. I'd have the codes scanned and see what you got. The cannister issue isn't going to give you a misfire it will give you stalling and rough idle.
Lets see what ECU is saying. You can go to Autozone if you don't have a scanner they will scan it for free. If scanning turns out negative than have a cylinder leakage test done. This way we can determine which cylinder has the problem and what the problem is.

Warning lamp flashing warning lamp shaped like a coiled spring started flashing. causing car to stutter badly. light went out when i restarted car.


Hi, that symbol is the MIL (engine check light) on the diesel cars. You probably have an intermittant fault, if you find someone with an EOBD code reader - which most garages have. They will be able to read the fault code which will have been stored relating to your fault.
Hope that helps Matt...
P.S If the fault relates to the EGR valve speak with your VW retailer as the car may need a (free I think) software update.

I have two warning lights on they are esp light and emission light please help . 2003 vw passat 1.8t


The eps light is related to your brake light sensor. The emission light you will need to have the code read. Go to your local auto parts store and have it read.
