Touareg :: 2004 V6 - Pressure Monitor System Fault Message

I have an 04 - V6 with about 55k miles. Tire Pressure Monitor System Fault is the message. The tire pressures are fine. Message appears after 15 minutes or so of driving. After another 5 minutes or so of driving, the fault message goes away - whey you click to vehicle status it says "OK". I took it to my local VW dealer, they said they fixed it, but on the way home from the dealer, it popped up again. They are perplexed. This is not the "Faulty wheel on board" message, it is totally different....

Phaeton :: Error Message System Fault Workshop With Audible Beep

I've been getting this "system fault workshop!" error message popping up like crazy. Its got a picture of a key, and makes the audible beep when it appears. on a short drive to work, maybe 10 minutes, it will randomly come on and beep anywhere from 3-10 times during my drive. The car starts and drives perfectly fine. This has been happening for a little over a week now. I noticed one post about this before, but that owner seemed to have different symptoms as their car wouldn't start. I really would hate to bring it into the dealership, as I've just paid them a small fortune fixing different things to finally get down to the bottom of it to find out i needed new fuel pump modules.

Ford Aerostar :: Erratic Idle - Air / Fuel Ratio Is Too Lean Or Rich For PCM To Correct

97 shortie. 3.0 245,000 miles. I've already cleaned the throttle body and the idle air control valve. Throttle position sensor reads 5 volts, good ground, and a smooth voltage increase from idle to wide open throttle and back down. Which of these codes is most likely to cause erratic idle? Mostly in the morning.

P0340 Camshaft position sensor.
P1443 Evaporative purge flow sensor.
P0401 Insufficient EGR flow.
P0171 Air/fuel ratio is too lean or rich for PCM to correct.

I doubt it's number 1, and number 4 seems too general to be any use. I'm leaning toward number 3. Seems I read somewhere that the tube from the exhaust gets plugged up. This started when I disconnected a plug from the blue air bag box to get rid of that beeping. Coincidence?

Ford 6.7L Power Stroke Diesel :: 2012 F350 - Exhaust Fluid System Fault Message

My 2012 F350 Lariat has 6100 miles on it now and on the way home tonight I got a "speed limited to 50 mph in 50 miles" message on the display. It states that there is a "diesel exhaust fluid system fault". The def was topped off about 2000 miles ago and the message center says that the fluid level is "ok". I am going to be on the phone with the dealer first thing in the morning. This is my personal/work truck and if I can't tow a trailer then I can't work. My guess would be a faulty sensor. I have no doubts that the dealer will get this resolved quickly as they have been great about everything else. I also want to say that other than this, I am sure minor issue, this truck is awesome!

Ford F-150 (2009-2014) :: 2011 - Hesitation From Idle - Missing Or Running Lean / Rich During Spin Up Of RPMs

I have recently purchased a 2011 F150 Ext cab with 3.5L ecoboost with 69k miles. I have no experience with these engines prior to now. I've always wanted a full size truck and after driving my 98 S10 for 17 years, I decided it was time for a new truck. I hope I made the right choice in going for the 3.5 instead of 5.0.

On to my question. I've noticed that the truck hesitates from a dead stop or anytime the RPM's are under 1k. It feels like its missing or running lean/rich during the spin up of RPM's. When I drive it hard, it does seem to subside for a little, and I've heard people say that they run better when run hard. I can attest to that, but is this hesitation normal for an almost 70k mile engine? I am getting 15ish MPG on almost all city driving since I have bought it, but I do expect that to change (job hunting and current commute is less than 2 miles each way).

The only time I get to open it up is when I go run errands out of the immediate local area or visiting friends and family. On one of those trips, before I noticed the hesitation, I attempted to accelerate from 60 to pass on the expressway and it bucked and resisted like a horse. It finally took off up to 80 and completed that journey with no issue but the check engine light came on for a bit. The check engine light went off when I shut it down and hasn't come back on since.

New ride: 2011 3.5L Ecoboost....

Golf IV R32 :: Airbag Light Came On With Fault Message

I have a couple of fun curves I hit daily and most days I push the car pretty hard. So, I hit one the other day on the way home from work and the freaking airbag light came on with a fault message. I immediately suspected that when my seat belt tightened that the sensor in the seat belt connector freaked out. I later scanned with VAGCOM and confirmed that I have the famous high resistance message for the driver side seat belt connector. I remember that some people had luck by cleaning the connections to the bottom of the seat and the switch. Maybe that is all I have to do. Got to love the .:R. I break stuff as fast as I fix stuff.

Golf VI R :: Idle Air Control System RPM Higher Than Expected - Fault P0507

Car started idling all weird this evening, rising and falling when at a stop light. Car APR Stg 2+. Found the fault code above. I changed the map back to stock and cleared the code and it still does it. I let the car sit for like 30 minutes and started it up again and it sounds even worse like it wants to stall. I did a few google searches and it seems that it could be a faulty PCV or throttle body. How should I proceed? I'm thinking change the PCV and if the problem is still there it's a potentially larger issue.

Ford 6.7L Power Stroke Diesel :: 2012 - DEF System Fault - Reductant System Performance

Sunday I received the dreaded DEF system fault message on my 2012 CC SRW SB FX4 with 7800 miles on it. Warned me that speed will be reduced to 50 MPH in 50 miles. I have a CTS Insight, so I checked for DTC's. First one was P2200 - NOx sensor circuit (Bank 1, Sensor 1), the second one was P204F - Reductant system performance (Bank 1).

After 50 miles it warned me that speed would be reduced to 50 MPH on next restart. Sure enough, Monday morning speed was limited to 50. I took it to the dealer, but I should have left it running. When the service guy started it, the fault had cleared and it no longer showed the P2200 NOx sensor code, although the P204f code was still there.

My question is, why in the world would Ford make it so that the code is cleared if the fault goes away, especially after putting you through the 50 MPH limit scenario?

Dealer did a reflash and said its OK now, but I'm not so sure. My trucks build date is 10/6/11. I read TSB 11-11-13 which states the NOx sensor module should be replaced for P2200 on trucks built before 10/11/11. Is that only for a persistent P2200?

Phaeton :: System Too Lean - MIL On

About a week ago the MIL came on and a VCDS scan (below) shows DTC P0171 & P0174 System Too Lean - MIL ON. I cleared the codes and the MIL came back on twice over the last week, both times with the same codes. I cleared the codes each time and it takes a while for the MIL to come back on. The car runs very good at speed but it has what feels like a little misfire at idle. This is especially noticeable when in gear, it seems the rpm drops a little bit every few seconds, but the time between those drops is not consistent. I made two videos to show this, see below.

I looked up the codes in the Bentley manual and it suggests the following:

SAE VAG Description

P0171 16555 System Too Lean Bank 1

Exhaust system

Exhaust system components, removing and installing

Fuel injectors

Fuel injectors, checking

[Code] .....
