Touareg :: Exhaust Emission Light Coming On Intermittently
Aug 9, 2007
My exhaust emission light has been coming on intermittently lately . I had it to the dealer last week but the light wasn't on at the time. The computer showed no error codes therefor they had no clue. When I took it in this week fortunately it was on at the time and must have triggered a computer error( cam fault ) What could this mean? I am supposed to take it back in a week. It seems to run ok but my gas mileage has dropped off about 2 mpg. there is only 22,700 on the clock...

I have a 2005 Ford Escape 3.0L V6. The emission systems/check engine light keeps coming on. I have taken it to 4 different places and the diagnostic keeps referring to the MAP Sensor. It has been replaced twice (granted one was free) and the light is still on. I have also replaced a coil, the plugs and boots.

I drove through some hills and inclines before reaching my destination. When i pulled over the lobby of the clubhouse, the guard noticed the smoke my car was emitting. I checked the exhaust and it did emit smoke all the way up to the parking area.
I parked for a good 1-2 hours. When i drove it again for around 10-15 mins up and down inclines, it was not emitting smoke.
Turned the engine off and parked for a good 30 minutes as i waited for someone. I drove back to the clubhouse and the car stood on idle for 10 mins.
As i took off, i looked at my side mirrors and noticed that it started emitting the same white/bluish smoke. This is my first brand new diesel car so I'm not quite familiar with how the appearance of smoke should be. My car is :
- 2015 purchased Tiguan 2.0 TDI 4motion, 140 Ps
- I have only driven it for 2000 km
- has been with me for just 30 days
- running on Shell V-Power diesel
The dealer said Tiguans really do emit smoke like this regularly. So I'm hoping this is not a symptom of any major problem.

I just purchased an '06 V10 a couple weeks ago. Today, I was about 11miles into my 15mile commute when I noticed A LOT of white smoke coming out of the back. The only time I'd seen smoke like that before was just before my old Ford Explorer caught fire. I immediately pulled over and took a look. White smoke (maybe steam?) was billowing out of the exhaust.
I say steam, because it didn't have the strong diesel smell I would've expected. I decided I couldn't sit there parked by the highway, so I got back in the car, checked warning lights and pulled out. Within 1/2 mile, it was gone. Nothing. No more problems the rest of the way. What this might have been? I have 1100 miles on the vehicle and this is the first time it's happened.

I described about 3 weeks ago this loud metal sound coming from the exhaust with any revs above 4k at stop or on the road. The car sounds like a Z06 Vette with out the cats on-it is really a loud disheartening sound. The VW stealership replaced the whole exhaust but the sound is still there. Where I should direct them to look??

Quick question for the techies of the group: my right brake light goes out intermittently. I get the warning in the MFI whenever it goes out. Lasts for about 10 mins and then works fine again for about 2 weeks, then another failure for 10 mins, then good for 2 weeks, etc. The dealer says the bulb is good and he can't find any other problem. Someone suggested there may be a short or it could be the wiring. But can I do if its never "out" when I bring it to the dealer and he says "what am I supposed to fix?"

Well after 8 weeks on owning this touareg this is the second warning light we have to deal with and also had the dead battery scenerio which took 2 trips for them to fix.. Man this is crappy for sure. I am busy at work and do not have time to search around so any info would be great about another TSB that I have to take in to the dealership or anything.

I drive a 2005 touareg with 111,000 miles. We are faithful with ALL maintenance. This morning I woke up to my car covered in ash (due to all the wildfires in the area I live...Idaho) and my exhaust warning light came on. It is steady yellow. Not flashing. My car drives exactly the same. I tried to contact the dealer but have not heard back.

My exhaust system light came on today shortly after re-fueling. I called the dealer and the service advisor suggested that I open the gas cap and re-close it making sure that it clicks. If that is the problem he said the light should go off in a few key cycles. There is no warning in the MFI. In the manual it says that there is an MFI warning about the fuel cap that says "CHECK FUEL CAP" and that the message will go away in about 10 minutes after you click the gas cap and restart the vehicle. I do not have anything in the MFI and it seems to be running just fine. (V-8)

I have 120K on my 2004 V6 and have been driving with the Exhaust light on steady for about 1000 miles. Tonight after filling up at my usual Chevron with Techron Premium gas station, my engine started stalling and I lurched the 2 miles home. I took off the gas cap to see if reclosing it changed things and it did not. I had the coil pack recall work done 30K miles ago. I'm thinking fuel pump, having it towed to the shop?

When starting my T-Reg leaving work yesterday, the yellow exhaust malfunction light (located in the rpm guauge -- it looks like an engine but the manual refers to it as an exhaust malfunction) came on and would blink now and then and remain on.
I proceeded to drive home and the entire ride was choppy and the engine was hesitant and misfiring. When I arrived home, I turned the Reg of and then back on again and the light never came on. I drove it around the block and it was fine.
We have been experiencing tremendous cold weather in the Northeast (-20 to -30 with the wind chill). Reg started fine this morning, no light. Was this a function of the computer resetting itself?

Since delivery a month ago we have had 2 minor quirks.
keyless locking/unlocking rarely works. Tried using the 2nd key for a day or so but no difference. No light in the remote or indicator in the dash telling me battery is dead...
The rear courtesy lights above the rear seats only work occasionally. All button settings seem to be set correctly to come on when th doors open but they don't . Most of the time you cant even turn them on manually but sometimes they work..

Intermittently the ABS Light is coming on. 84,000 miles.
Brakes have been changed once, 10,000 miles ago.
Minor clunk sound when light is on.
Light goes off after van has set, brakes work fine at that point.

Yesterday my light went on for the exhaust warning. Does this mean I should now drive with a window open? And how serious can it be? Also, about 2 months ago I was told I need a serpentine belt. Would this have anything to do with the light coming on? You see, last time I wrote in here, I was told I needed new front brake pads and rotors. I was told from folks here that the dealer's quote was 2X what it should be, so I am hesitating to go back to same dealer.

2005 Camry LE 4 cylinder, 141K miles.
For 6 months the battery light has been coming on intermittently, sometimes not coming on for two to three days and then does it again every so often during the fourth day and so on. Until recently, it's gone a record 6 days without coming on.
However, today it's stayed on all day. Usually, when it does come on, it will go back in in a minute or two. I'd gotten used to it, since the car has always started like nothing is wrong. However, tonight the ABS light came on with the battery light, then the Safety Bag light came on. Then, the radio died, clicking, static, then just dim light, The clock dimmed when the headlights were on, and the headlights weren't as bright as they should be. Stopped the car in a parking lot. Wouldn't not start again, but the dash would come on.
Got a jump and the car started up fine, but there wasn't enough power getting to anything to make the car do much of anything. The car didn't seem to have enough power to send to the transmission to shift, pressing the brake pedal made the dash go black.
Sat a while, got the car to start again, with a fight. Enough power to shift getting to the transmission, but quickly all the lights started coming on one by one again, and none of the lights were bright as they should be. Back to square one.
Just the battery? Replaced the alternator a year ago, when it killed the last battery. The current battery is a year to 13 months old.

As the title states, my brake light on the dash keeps on coming on intermittently. I can't figure it out. Fluid level is fine, and I added more just to be sure. Pads and rotors all got replaced within the last 9 months. I don't see any chafed or broken wires to the wheel/abs sensors. I don't know where else to look
Also when the light comes on the pads on the rear passenger side seem to drag a little bit. I can't feel it, but I can hear it just slightly.

'08 Ford F-150 with 53,000 miles. ABS indicator light has been coming on intermittently for a week now. Mechanic said its a left front wheel sensor code. Wants to charge $98 to diagnose. Says it could be bad sensor or broken wire.
I have limited mechanical experience. Is this something I can tackle? Or is this a major job?

Mechanics are stumped. 3 months ago, during a 4WD commute through the snow, I started noticing what at the time smelled like bus exhaust coming into the cabin. My SES lights comes on for 2-3 days, then off for 2-3 days. Codes say MAP sensor and low coolant coolant.level. When the SUV warms up fully, you can smell the odor strongly under the hood, inside the cabin while sitting at a stop light, and inside with the Heat or AC on. Mechanics had the car for days, replacing cam and Map sensors. There is no evidence of exhaust leaks or coolant on the engine. Level of coolant has been dropping slowly in the reservoir.

My red airbag light on the instrument cluster is coming on intermittently. Off to the dealer to try to solve the problem. Not how I envisioned my first full day of ownership!!
