Phaeton :: Refuses To Start After A Brief Stop - Temp Sensor Failing
Jul 31, 2009
My Phaeton is experiencing issues with the temp sensor. After running the car for a while, then a brief stop (10 minutes or less) it refuses to start. (It cranks but does not start) After a while, it starts fine. No check engine light comes up.
A quick Vagcom read (not the dealer's Vagcom) does show the temperature sensor is reading really low temperatures where it shouldn't. We think this temp sensor gone awry is messing with the fuel mix.
So in the parts book, we see only one temp sensor coming off the radiator, is this a 'easy' fix or do I need the dealer involved?

Where is the ambiant outside air temp sensor located on the Phaeton? I know it is located under the outside left or right mirror (based on model year) on a Volvo but not sure where it is on the Phaeton. No problems, just curious.

I have a 5.0 Explorer 1998 and it has a problem for which I cannot find a definite solution, everyone says a different thing. The problem is that when the weather is hot, sometimes the engine does a strange thing. You ride the car for some time, especially if you do it on a high speed so the engine is really hot (but no overheating symptoms) - and then you kill the engine and leave it for a few minutes - to walk into a store, let's say.
After that you attempt to start the engine... sometimes it starts, but there were several times when it refused to catch, it cranks, at first tries to start, but stalls... then it just cranks without even attempting to start. And I had one occasion when it stopped working right in the middle of the road while crawling in traffic, but it was really HOT outside. Luckily, all other cases were in our town, so I could at least walk home. So, the problem seems to overheating of something, as in normal or cold weather it never happens. And every time, after the car is left to stay in place for some time, an hour or more, cannot say exactly - it starts perfectly!
I am really tried of this and want to eliminate the reason. But I am hearing so many different opinions about this problem. I thought that it could be the overheating of the fuel pump. But then it would stop working while moving, not after you shut the engine off and the pump cannot be still working and overheating. The only place where the heat can build up when you stop and turn the engine off is under the hood, as the fan stops, the coolant pump stops and the air isn't blowing as the car isn't moving. But the pump is in the tank! And I never ride on empty fuel tank, I always keep some level, lately I tried to keep it even higher, but yesterday it refused to start when the tank was almost half-full. Also, if it was just dying - a dying fuel pump gives certain symptoms like slow acceleration, engine shaking and trying to stall when you press the pedal, sudden stalling, uneven idling etc. In this case, nothing like this. The car's behavior is absolutely normal, acceleration good, normal idle. It happens ONLY under certain conditions, involving heat.
Other people say that it can be due to low pressure in the fuel ramp and the gasoline is starting to boil at some moment, when the temperature under the hood rises to a certain point. As a reason they name the pump (but as I said, I doubt it) or the fuel pressure control valve - don't know its exact name, it's a valve which maintains a certain pressure in the fuel ramp and releases excessive pressure by returning some fuel to the tank. However, when this valve gets stuck and doesn't maintain pressure, it mostly influences the cold start, as the fuel pressure drops and you have to crank for a long time while the pump is building the pressure again. But my car has never had any problems with the cold start, it's always instantaneous. Also, when this problem occurs and you start the engine after it cools down, it catches instantly which means THERE IS pressure in the ramp. So I don't believe in low pressure, gasoline boiling and resulting vapor jams.
And finally, I read that it may be caused by defective/dying engine temperature or crankshaft position sensors. As for the temp sensor, I will replace it tomorrow anyway. I am also thinking of having a look at the crankshaft sensor, where it's located on 5.0 V8?

My CEL came on and the code said Coolant Temp Sensor High Voltage. Since there are 2 sensors, and my gauge isn't reading off, about 200F constantly, I assume the bad sensor is the water pump sensor. Also, is there a diagram of the sensorny locations and the easiest way to access them to swap them out. I have already purchased the sensor and gasket, just don't want to replace the wrong one or screw something else up in the process. It appears to be an easy job.

I just had an OBD code pulled on my 2010 Camry and it turns out that my Heated O2 sensor for Bank 1 Sensor 2 is failing. I'd rather do this myself if I can but I can't figure out where this thing is. Is this something I can access myself and swap out? Or does this need to be fixed by a mechanic?

In the past few days, I've noticed that when my headlights are on the white backlighting of the speedometer, tachometer, and other gauges in the instrument cluster fail to illuminate, however the red needles within each gauge do illuminate properly. Furthermore, the rheostat adjustment does successfully brighten and dim the red needles, but the faces of the gauges remain dark. I checked fuses 23 and 27 and both are fine.

Started it this evening and went to the store, on my way there the car was right messed up. No lights, wouldn't go over 500 rpm (no throttle response), eventually was stuck on the side of the road. Reset my throttle back to OEM and everything went back to normal, car hasn't shown any trouble since but it's only been a couple hours. I don't want to end up stranded somewhere so I'm wondering if my computer is possibly failing or should I try replacing the throttle body if it does it again?
Car is not chipped and was OEM throttle before (to my knowledge).

Lately I've been getting the Stop! Car too low! message when I start the car if it has been sitting more than 6 hours or so. the front appears to be too low. After 20-30 seconds, the front end raises up high enough and the message goes away. It didn't do this when I first got the car. I'm going in for my 80,000 mile service soon.

I have a question, regarding the 5.0 v10. When i accelerate from stop, it has a delay, and a slow start, something like it would start in 2nd gear, but it doesn't (it's in 1st). Is the torque somehow limited whet accelerating from a complete stop? Because while driving, the acceleration is instant, and drives normally.

I did the installation of the start/stop button and it works. However, I have some unresolved issues. I have done a search in the FAQ thread but could not find anything referring to the following:
1- When I lock the car, either with the fob or with the door buttons, the alarm will sound when I enter the car if I unlock it using the door handle sensors. I can disarm the alarm with the fob, but it is not disarming with the door handles. How can I solve this issue so that the alarm is disarmed with the door handles? Can this be solved using a VAG-COM?
2- When I turn on the alarm, either with the fob or the door handle, the alarm indicating light blinks for a few seconds, then goes steady, and then blinks normally. I had not noticed this steady light state before. My alarm, I think, always went straight to blinking and stayed blinking
.
3- When they gave me the car back the adviser said that the seat would not move and the trunk would not open. However, I think they ran down the battery because the interior light was on. The dash displayed the "start the car now" message.
a) I had an almost two hour drive back home, do you think that the battery recharged in that time?
b) Was there any lasting damage done to the battery?
c) Is it safe to charge the battery with a trickle charger or do I need a special and specific charger?
The trunk now operates OK and the start/stop button also works. I wish the alarm also did.

I can not start the car by pressing the Start / Stop button. The display shows the message "Key Non found". Remote control key with normally opens and closes the car but the car itself does not open the approach to it. I have two keys and the two are the same.

Any ls600hl owner experienced this? --> When the car is left on acc for a while (all electrics system online without the engine running - or if the car is started with radio only then shut off a few time) the parking sensor suddenly start beeping non stop. If you shut down the car then the steering wheel won't go back into neutral position.
If you try to start the car (along the engine) the car does a kind a "air deflating" sound and won't start (don't seems to be the suspension thought). Then the light on the Mark Levinson radio start flashing intermittently and a warning about the SRS is showing telling you to go to the dealer to have the car inspected.
If you wait a few minutes and start the car again it will then start normally without problems and won't display the SRS warning anymore. This is my second 2008 ls600h with the executive trim and both did this so this seems to be some kind of design flawn.

My Taurus has developed a problem where it refuses to start. When I try to start it, it just cranks over and over and over. I keep trying till the battery starts getting weak. I charge up the battery and then try it again with no luck. A neighbor suggested I get a piece of lumber and gently pound on the gas tank suggesting it might be a stuck fuel pump problem [whatever that means!]. Actually it worked once but after I drove the car all day doing errands the next morning was the same problem. That was three weeks ago.

I've got a 99 dodge ram 1500 sport, with nearly 250k miles logged, and it refused to start up this morning.
It ran fine this past friday, aside from a horrible squealing noise it made. It has power, its getting fuel, and it coughs and sputters like it wants to start, but it refuses. How do I get this thing to come back to life?

96 intrepid, 3.5 motor. Runs fine, no loss of power or odd behavior but will just die. Like flipping a switch. Refuses to start. I checked fuel pressure and it's good. No codes. Does this motor have a MAF? Sure can't find one. It has the odd split intake plenum. 1 air box but 2 separate inlet ducts to each side of motor. The motor is not transverse. It has 2 throttle bodies on the firewall side of motor with a shaft that runs between them. So eventually it starts. Idles fine. I watch it idle. And click, it shuts off.

On Saturday afternoon of Labor Day weekend my dad's 2003 Ford F250 "died" in the parking lot at my work. It had been running fine all morning, but then I stopped by work, and when I went to leave it barely started, ran for a few seconds at a rough idle (presumably on whatever fuel was already in the system), then died and would not restart. Turned over strongly (new battery a few months ago) but no ignition. Checked the fuses and fuel pump interrupt switch, but everything was fine. Had just put 15 gallons of gas in earlier in the week so I "knew" that wasn't the problem.
When I had it towed to my mechanic. He didn't get a chance to look at it until the weekend, and called me Monday to say that it started just fine for him all weekend, but it could use some gas. I knew I should still have 12-15 gallons in there, so we came to the conclusion that someone had siphoned my gas. Monday night I picked it up, feeling dumb for not checking that more carefully, and drove to the gas station. Sure enough, the gauge registered "E" and the low fuel light was illuminated. Put in 8 gallons. Started the truck and the gauge popped up to 3/4 tank.
8 gallons is NOT 3/4 of a 32 gallon tank. It's 1/4. The original fuel was still in there! On the way home from the gas station I stopped by work to load up the lumber I had to leave there the first time it died and--you guessed it--died like before. This time the gauge definitely read 3/4 tank with the key on, so the problem was not low fuel. I didn't want to pay to have it towed again, so my mechanic said he'd come look at it when he got time. I tried to start it a few times throughout the week and on Saturday it started right up and ran strong all the way to his shop, where it continued to start every time we tried it. It could be the crank position sensor, but the confusing part is the low fuel indication.
Could the fuel gauge have gotten stuck when the truck was was pulled up on the rollback? And would it have stayed like that all the way to the gas station? I also don't think it's the fuel pump because it runs so strongly when it does start. The second time it died the gauge still read 3/4 tank so I don't think it's related. The mechanic can't fix a problem he can't reproduce, and I really need the truck to pull my 3,000lb landscape trailer on the weekends. My 2000 Wrangler isn't exactly ideal for the job! Oh yeah, the truck is stock, 5.4L gas, off-road package, tow package, extended cab, long box, auto trans, 85K miles.

I am the owner of a 1992 ford ranger 4.0 that refuses to start. She turns over, but theres no pressure coming out of the fuel rack/valve. Might be the fuel pump but it started with a little boost about a month ago and now nothing. Head gasket and transmission have been tuned up as well! I've also checked the power distribution box, and spark plugs both seem to be doing thier job! What am i missing?!

Occasionally, when restarting my 2003 Santa Fe V6,it refuses to idle. If I manually press on accelerator pedal it will start and run and after a few moments it will run fine. This seems to happen more often in high temps i.e., deserts.

Love the car, but in the last 2-3 three weeks it just randomly refuses to start. Turns over fine but seems like its not getting fuel. It is most likely a relay that needs replacing. This relay apparently controls the computer and the fuel pump. Maybe I'm just looking in the wrong place. I hardly dare drive my car anywhere now for fear It will not start when time to go home.
In the meantime, I seem to be able to get the faulty relay to function (if that really is the problem here), by making sure lights and radio are turned off, and by turning ignition key just one click (listening to be sure fuel pump has loaded the lines) before actually starting the car. No point in running battery low cranking engine over and over, waiting for that magic moment when the car suddenly starts like there was never any problem at all.

I have a '94 XJS Jaguar that has been having repeated issues starting and has lately been putting out a dramatic plume of grey smoke each time has actually succeeded in starting. Currently, the engine refuses to turnover (or even give the usual "crank"); however, all the electrics in the car - lights, radio etc - seem to work perfectly fine.
Attempts to jump the car have proved futile. Previous trips to the repair shop have included battery replacements, battery cable replacements, tightening of this, that and the other thing as well as a transmission cleaning, all to no avail. What the issue might be?

Our Grand Am runs well when it decides to start! But occasionally when the key is turned all the way on, the starter may take a few minutes to engage, or not at all. Usually it just starts right up, but not every time, so it is not reliable. The key lock cylinder has been replaced.
