Question about 2006 Volkswagen Touareg

1 Answer

The engline (exhaust light) on in 2004 VW Touareg.

Does it have to be that my catayltic converters are bad?! Please say no!!! Its a 2004 V6 with 84,000 miles on it. I'm in the process of selling it to the highest bidder and I can't afford to replace the cats (was quotesd something like $4,400). What else could it be. I do need an oil change.

    Well I know that my catalytic converters are bad the VAG-COM has been run but what I want to know is, could there be anything else that makes the exhaust light come on? I just want some suggestions.

    emissionwiz - thanks for the suggestions my hubby will love "running the car ******* the freeway". We are now having another symptom - smelling gas - its not in the cabin of the Touareg but on the outside. Asked hubby if he spilled gasoline - said no - its really strong in the garage. Could this be a new problem or is it related to the exhaust back pressure sensor issue? Any help is greatly appreciated.

    Mine is the same. Constant exhaust light and no message as the manual says. Do get the gas smell in the garage after pulling in and car sits. Light went out for a while and then came back on. 2004 V8 32K miles. In Colorado high country. (cold climate) crappy ethanol gas too.

This is not a check engine light? this is what i found at a owners club site, 1st try running the car hard on the freeway to burn of the carbon that builds up in the particulate filter, next replace the exhaust back pressure sensor, this is not the cats.

04 saturn ion ran good when parked started in morning shaking bad check engine light flashing has 7e9 code for 2 months

Check engine light flashing means you have catayltic converter damaging misfire . Don't know where you came up with 7e9 code . This has nothing to do with OBD2 and isn't a code . WithYour lack knowledge of this basic stuff ,your best bet , take it to a qualified repair shop .

I have a 1998 saturn Sl-1. It has about 200,000 miles on it. Is there any hope for passing the smog test. If not about how much should I set aside for repair? How about for my Husband's 2003 Allero?

Sure is. 200,000 isn't a ton of miles on these cars. As long as the maintenance has been kept up and regular items have been changed over the life of the car then you shouldn't have a problem. Sometimes though at this age the catayltic converter may become clogged but this is usually preceded by bogging down under acceleration and other power problems.

Transmission completely quit working with no noise. Reverse worked for 10 min and the quite as well.

It sounds like you may have a sun gear failure. Before we go there check the fuse for the transmission, make sure it's still good. Good luck and keep me posted.

Catayltic converter

Yup, no back pressure, + added temperature with converter on, throws off the readings of sensor.
