Phaeton :: W12 Does Not Fire On All Cylinders / Eventually Exhaust Symbol Lights Up
Dec 10, 2007
I've had problems with my w12 2003 in that it doesn't fire on all cylinders. Eventually the "exhaust"-symbol lights up and I had to take it to a vw-center. They did change 1 "ignition coil" (if that is the right term for it) and it worked fine for some months. But last week it happened again, it is rather awkward since you get heavy vibrations from the normally unperceptible engine. I had to tow it to the same vw-center and now they change the remaining 11 "ignition coils". However it doesn't run true...! The "exhaust" symbol didn't light but the motor didn't fire on all cylinders, it was quit noticeable. Is this a known problem? What else than the "ignition coils" can be the cause of the problem?

The Phaeton is really a creature of its own. It is not a year since I bought my 2003 W12 and have had it towed three times since. The latest bother is that the engine doesn't fire on all cylinders. The ignition coils have now been replaced on all cylinders, and first it seemed to be fixed but after some thousand kilometers it misfired again. As always on a Sunday on a long trip... the warning lights go on and this time I just drove along despite what the manual says. It wobbled along and after maybe 10 kilometers it get fired on all cylinders again. The warning light is still on though.
Now after having drove the car a couple of shorter runs the ignition works fine and now the warning light, today, wasn't on. So is all well and dandy now? Another little bother, the back door, behind the drivers door, that one cannot be opened. Sometimes it opens sometimes not. No matter how many times you press the "open" button on the remote control, it doesn't open. No matter if you press the button above the inside handle, it doen't open. So, out of the blue, it opens ok! How about that one????

1 out of the 4 cylinders won't fire. The coil, spark plug wire, spark plug, fuel injector, and the wire going to the fuel injector all work.
My dad mentioned it could be a stuck valve, but he doesn't really know much about cars and I have never messed with valves before. If I could manage to get to a valve and it is stuck, do I have to pry on it to unstick it or grease it up? Or does it need replaced?
I forgot to mention that there is no new noises and the FPR isn't showing the fuel line is holding pressure when the car is off, even though I'm pretty sure it used to.

One morning I took the car out to the mall. Right away I had the ESP light on and stayed on the whole time. Tried turning it off with the ESP button to no avail. Got to the mall and let her sit for a few hours. Came back out and started the car and now two light are on. The ESP and Exhaust system malfunction. Found a thread that had the exact same problem as I did. He said the Mass airflow sensor must be bad. So the next morning I popped my hood to find out that a little mouse had made its nest in the engine and had bitten into the wiring harness that lead the the Mass airflow sensor.
I tore apart the tape and found that only the red wire had been chewed all the way through . I soldered the wire back together and re-wrapped the tape. Couldn't find any else around the whole car that was tampered with so I thought I was good to go. Started the car and both light are still on..Drove it around a couple more times to see if that would take them warning light off, and still no go. So I am guess this has to be removed by the dealer is the only way to go?

My 2006, 4.2 has been really erratically not starting. Turns over fine but will sometimes fire up and tries to run on maybe 2 cylinders, then stalls. Now it won't even do that, nothing. No check engine light or codes. Guess what the thing started up this morning 7 degrees out and running like a charm. Turned off and nothing again. Replaced relay for PCM ,no change, still no codes.

I have entered too many symbol on my sat nav map display, e.g., petrol station, car park, train station, etc. The map display looked very congested and would like to delete some of the symbol. There is no instruction in the handbook for removing the symbol.

Going down a steep hill tonight. Been running for 30 mins - all 100% fine. Was in 2nd gear - had selected it for engine braking. Suddenly got Engine Fault Workshop message - ABS warning light and flashing glow plug symbol.
Continued to drive fine. Definitely not limping! Came home and scanned it. First scan had ABS intermittent fault. Cleared all faults. Engine Fault warning in MFD has now go. Still drives fine only with annoying flashing light!

Today the solid engine symbol showed up inside my tachometer (no workshop message in the instrument panel display). The owners manual says this is an exhaust system problem. What do you make of the following scan:

No indication if related problems other than a cam position sensor CEL a few months ago. I've run VAGCOM a few times with no engine or electrical issues. I simply turn the key, engine turns, but no fire. Turn ignition off, try again and it fires.

I have been having trouble with a hard cold start on my W12. when I go to start the car it will crank and crank I can hear it fire on a few cylinders but is not starting on the first try. It will then fire right up on the 2nd try and is fine when it is warm. I had it into the dealer and the replaced the battery in the key and cleared the misfire codes they also did the coil pack swap. I am still getting the hard starting...

Still trying to track down my electrical issues. While poking around in the engine compartment near the fuse panel by firewall - i heard a clicking sound coming from the two cylinders near the fuse panel.
They are cylinders - side by side - about 1 1/2 inch wide and 2 inches tall - with electrical connections and either fuel or vacuum lines attached. What are these? Some sort of solenoids? Are they part of the EVAP system?
How long should they continue to "click" after the car is turned off? Mine kept going for a half hour. I then disconnected the left side battery and it stopped. 5 hours later after fully charging the battery I hooked it up again - and the clicking came back. Is this normal or could it be a source of my battery drain?.

Love my 2007 Buick LaCrosse. It has just under 40,000 mi. Oil gets changed regularly, etc. Never had any real problems (knock wood). Past six months or so, the airbag symbol lights up for no apparent reason, stays on a little while, goes off, maybe comes back on again same day, maybe not for a week or two. Took it to local Buick dealership service department twice; they can't find a reason & said that the computer check doesn't even show it coming on. Should I be concerned? Will airbags deploy if/when needed? Don't know what to try next, if anything.

I have a 2006 Prius hybrid that will not start. A few days ago I was driving in a storm, parked my car for an hour and when it was time to leave the car wouldn't start. The interior light, power locks, brake lights Ann hazard lights all work. No dash lights or radio come on.
I had two friends with two different cars try to jump the front and back battery and still nothing.

I first thought it was just a cold thing, but now it's not starting at all in a warmed garaged. The electrical system seems to go in and out, makes this crazy clicking kind of noise, and eventually will make the dashboard lights go entirely, the message system saying then the breaks have failed, pull over, etc., On a cold morning it won't crank, and when it finally does it will immediately shut off. Once I finally overcome it, the electrical system clicks and clicks, and eventually will lose dashboard lights and functions... no turn signal, nothing.
If I can get driving for 15 minutes or so without the electrical interference happening, it will run fine like normal and I can restart the car fine the rest of the day... but the next morning (especially if cold) I go through the process again.
Now it's just not cranking at all...it's clicking, but it sounds like a louder clicking than a dead battery... it's like the electrical system is overriding it entirely and won't let me get the car started at all.
Other symptoms: when I get the key near the ignition (not putting it in) the clicking of the electric system starts. Interior lights flicker, etc. Today it won't start.

Starting a few days ago, three lights on my dashboard display started to turn on. Sometimes they don't turn on for a few minutes after the car is running, but they do eventually turn on. The first is a red "BRAKE" light above the gas gauge. The second is a yellow/orange "ABS" light above the speedometer. And the last is a yellow/orange symbol of a car sliding, or swerving, this one besides the RPM gauge. What do they mean and why would they suddenly start turning on together?

Driving home today, my prius threw the triangle and all the other warning lights. Scanned with my scan gauge got code u0100. I was only a mile from home so attempted to drive it. Car made it 1/4 mile and then died. I had it towed to the house and checked the grounding wires going to the engine and transaxle. The Tranaxle grounding wire was loose so i pushed it together tightly. The car now runs on main battery only, the ICE does not fire up. All warning lights are still present. Nav screen says problem. 12v is good.

Exhaust systems warning symbol that comes on if there is a Exhaust system problem. Yesterday when headed to lunch the warning symbol came on and it startled me as its a picture of an engine block. It was a solid symbol vs flashing. The Phaeton seems to be running well and the book does say get it in to be checked.
Mileage is 69,000

I recently took my car in for service and complained of the exhaust clicking (very audible) after the car is off. This clicking can also be heard when the car is running too - it is not as prevalent though. The service advisor said she spoke with several technicians and they said this was normal. The reason they cited was the stainless steel exhaust system in the Phaeton. They also said that humidity will exacerbate the sound.

From time to time, i get some exhaust smoke smell in the car, when driving slow or standing in a queue.
90% of the time everything it's perfect, but at a sudden moment, the rpm is rising with 50 or so, the instant consumption rises from let's say 1.4l/h to 1.8-2.0l/h when in gear and standing, i get a small vibration and then the exhaust smell appears.
If i'm closing the recirculation, then no more smell.
After 15-20 min, everything get back as it use to be, 1.4l/h consumption, no vibrations no smells no nothing.
This i think happens when the dpf is cleaning and i cought with vcds of a friend when it happened and the exhaust temp was 350 celsius or something. Usually is 200 degrees celsius, so it is a dpf regeneration. Also the car is running smoother after this.
Still..the smoke smell... it's annoying and quite strong. There is no sign of smoke from the exhaust pipes, flexible pipe or whatever. There is no sign at all anywhere.
I have a small theory but i don't know from where to start. Usually the catalyst temp is 200 degrees. When it's 350, it expanding more, or at least the cracks are expanding and smoke+smell is from there...but there is no sign anywhere.

So, I just hopped in my car ready to go to work, and my "exhaust" light came on. I drove it a block, and it seems very "jittery". I decided not to risk driving it, and am getting a lift with my wife.

My exhaust system warning light came on this afternoon. Think the cars needs to be parked until I can get it to the dealer.
