Question about 2006 Volkswagen Jetta

1 Answer

I have a 2006 Jetta 2.5 AT 5 cyl. I recently had the Exhaust system malfunction light come on the dash and starting yesterday my car has experienced rough shifting from 1-2 and 2-3 gears both on acceleration and deceleration. Is this problem a direct relation to a transmission problem or something easier like a catalytic converter? Or best scenario, I just need to replace the spark plugs?

This may be related to converter, the converter may be plugged, this will cause problems with the shifting, have the computer scanned for any stored codes. also make sure to have the 02 sensors checked.

2006 Jetta Exhaust system light on again.. It first came on 2 weeks ago when the weather got very cold. I had just put gas into my car and the dealer thought that was possible I just didn't tighten the...

ignoring lights leads to complacency and a large repair account that could have been avoided if attention was paid in the first place
exhaust light codes are in the p1400 list and refer to the EGR valve system ( exhaust gas recirculation)
I would find an accredited service center that has experience on your make of car and have the fault codes read and the problem properly diagnosed
what you dealer stated about the gas cap is an EVAP issue and if he didn't read the codes first , he has done you a disservice and not attended to your concerns properly

My exhaust system warning light is on. What could this mean? I have just had the oil changed and use regular gas. I always tightened the gas cap fully after several "clicks". thanks

could be one of two things either your cat is failing or the lamba sensor on the cat which measures gasses in the exhaust system has failed which will illuminate the light on the dash

I have a '96 Jetta, and i got P0440, P0302, P0172 and P1613 codes. How can I fix this? I have to go to emissions test this month, but my check endine light comes on because of these problems.

P0440- EVAP Emission Control Sys Malfunction

Something unspecified is wrong with the evaporative emission system. Check vac lines. Could be a loose electrical connection. This code has a very vague description.

P0302- Cyl 2 misfire

Has the car had a tune up in the past few years? Check plugs and wires, test for spark. Maybe a compression test. This issue may cause the next code.

P0172- Fuel trim Bank 1 , too rich

I would clear up the misfire first, then this code might go away.

P1613- MIL Call-up circuit open/Short to B+

Check the wiring under & behind the dash and instrument cluster. There apparently is a wiring issue, or the dash itself is shorted

Exhaust malfunction light will not go out...on 2006 jetta

could be as silmple as a loose gas cap or a failed fuel system componet, you will need to have the system "scanned" by a service station or dealer to narrow down the problem

Exhaust system light is on - 2006 Jetta

What you here running after you shut your car off is just your exhaust fan. Your turbo will not continue to run. As for the oil change effecting the exhaust this may be an issue. IF they actually drained the regular oil and then put synthetic then you should be ok. But if they just put more in on top then they may have messed up your Cat converter...good luck with everything
