Passat (B7) :: 2012 - Dash Display Shows Incorrect MPG?
Apr 21, 2015
Just bought a 2012 2.5l last week, and have a question about the MPG display on the dash. When I bought it from the dealer it had a full tank and it showed I had about 500+ miles left. Yesterday I filled up the tank again and now it only showed I have 405 miles, but as I drove it bounced around from 415-400. after driving about 35 miles its still at 405 miles. Just wondering if this is how it's supposed to be, if I have to reset something every time I fill up, or if something is wrong? I've always had mk4 so I'm not all up to date on the "new".

Just hit 70,000 miles and went out of warranty. The issue is the Heads Up Display periodically shows "Check Back Up Sensor". When this occurs the sensors do not detect, and this doesn't happen all the time. I did clean the lens on each of them.

So I'm not new to fixing this car but I'm now stuck. It is not the inhibitor switch, I had that replaced, and the car cranks so it is not the problem. In addition, the "P" shows up on the dash. Since the car cranks, its not the battery, it is showing 12.25V.
I am afraid it is the fuel pump. Looking for the specs for the fuel pump such as resistances/ voltages? Sometimes when it cranks, I believe it ignites for half a second and then dies. Then it cranks with no ignition, then it sounds like its dying, then it ignites every once in a while.
Similar to this: [URL] ..... but without the nastiness at 0:08 where they turn off the car mid crank.

I bought a replacement bulb, swapped it out. No dice. I swapped over the passenger side low beam and still no dice. At this point I know its not the bulbs. I swapped in the original Driver's side light to the passenger side and it works. So now I have an extra bulb.
But the light is not working when I know the bulbs are good. Is this a fuse problem? It just happened one day while driving home from work the light shows up.
How should I go about fixing this and is it most likely a fuse that has gone out or something far worse?

I had this in my 06 Passat, it was turned on by the dealer I guess, my 08 Passat doesn't show it. I know there's a little trick but can't find any info.

With my B6 '09 wagon, when I turn off ESP by pressing the console button, the icon flashes on the dash display and then goes out. Is this working correctly? I would think it would flash when ESP is on and it has encountered slipping and corrected. With the button set to off, I would think the light would stay lit on the dash?

So computing avg fuel mileage. There are a lot of times display shows max of 99.9. Does the car use that number to compute av?. Or is that just the display's max and the car knows it is 155 or infinite mpg. (rolling downhill gen charging HV batt using no fuel actually more than infinite mileage)

So I've been able to suppress all of the rattles in my car except one: The cluster trim right above the display rattles, it creaks, hell, I can hold a conversation with it. What can be done to remedy it? The 'turn up the radio' technique doesn't work.

I like to efficiently use my regenerative braking. Proof of that is that I have 107K miles on my 2008 and haven't had a brake job yet. Referring to my 2012, on the Hybrid System Indicator Screen, there is a CHG bar. The harder you brake, the more the bar fills from right to left. When the bar is full (when braking harder) do the brake shoes offer the balance of braking power needed.
Does the CHG display indicate that much accuracy?

I saw a really weird thing happen about half an hour ago. Hadn't driven that car today until I made a quick trip a bit ago to pick something up.
As I was coming back from the store I noticed the display was showing extremely low numbers with barely any speed/coasting. After I got up to ~30mph and started slowing down, I noticed the display was actually showing the mpg decrease as I applied the brake.

The shifter goes into the incorrect gear for what is showing on the dash.
For example:
A little left of Park = Park
Park=Reverse
Reverse/Neutral/Drive = Neutral
A little right (almost gear 2) of Drive = Drive
Once I have found the gear and the shifter is set, the handle has enough play in it that allows it to rest over the correct slot.
It started after I put the car into neutral from drive without pulling the handle back but instead just pushing it to the left. When I went to put it back into drive, it was still in neutral.

Everything was going good on my V8 until this week. Out of nowhere, the following happened all at once:
1. Display shows the hood as open, even though it is not.
2. Wipers work only when they want to
Also, cover to ash tray/lighter in center console popped off its tracks.
How to deal with this stuff on my own, or am I headed to service?

I just picked up an 05 6.0 Limited and love it, but I can't figure out the overhead temperature gauge. It shows -40 degrees no matter what, but if I hit the outside temp button on the climate control, it shows the (mostly) correct temp. I verified that the temp sensor in front of the radiator is still there and hooked up, and it seems to me that Ford wouldn't go to the expense of using separate sensors for each readout, so I'm guessing that the problem is in the overhead unit itself. All of the other functions (compass, mileage, range) work just fine. I've seen several threads about the overhead dying completely as chips rattle loose. Is it also common for just specific functions to go out as things start to shake apart?

My MFD now only shows the Toyota Logo, whatever I do. Also, I cannot play music. The trick with pressing (hold) INFO and headlights three times does not bring up a diagnostic screen. My theory is that the MFD is waiting for some signal over the network before showing the usual screen (and it never gets that signal). Some years ago, I had a third party fit a new audio tuner and player (non-Toyota), and that worked more or less fine for years.
They had to leave the old faulty Toyota audio in the circuit to make it all work, and they said to leave the graphic equaliser on even settings, and then forget it. The old Toyota audio CD changer had failed, but the rest was OK. My 'guess' is that they had to leave the old audio device connected because it terminates the AVC-LAN with a 60 ohm resistor. Maybe that connection came off, and now the LAN signals are not good, and the MFD is locked up 'always waiting' for the signal from an ECU.

My accent currently has just under 17k and about two months ago displayed a cel. I plugged in my innova 3100 code scanner and it displayed p0441. saying it was incorrect purge flow. My question is.. is this covered under the factory warranty. I'm on a very tight budget and I'm trying to find out before going in and finding out. I've owned Hyundai's since 2002 and so far have never paid for an out of pocket repair. But it doesn't hurt to check ahead.. And I've already gotten the standard "it's your gas cap". Ok I'd buy that if it was 10yrs old but it's only a yr and a half old. besides it only goes half a turn then clicks. so it kind of either seals or it doesn't.

Today morning, when I started the car and backed out of the garage, the rear view camera display was not lit-up. Normally as I get out of the garage, it senses the change in outside lighting & changes the brightness of the display automatically.
After backing up, I put the car on Drive and then on Park, but the display was totally blank. No audio nor response by touching any buttons. Then I turned off the car & restarted it.
Then the display came up, but with this weird looking screen, which I have never seen before in the 5 months that I have owned this car..
It lasted for about 30-40 secs, with the progress bar moving all the way across. Then everything was back to normal!.

So I got my 92 Celica GT 2.2 Motor Auto (unfortunately for now). Back off my wife's uncle and it wont crank or anything. I also noticed that now when you push the brake, it still wont let u shift it out of park. If you try to start the car it does nothing, however the brake light on the dash shows up. I am thinking it may be the starter as all the relays and fuses look ok. I am thinking it could be the ignition switch as it wont let me shift out of park without using the release button, but am not sure where I should start.

I tried to turn on my car this morning, but the "Ready" sign didn't go on. The whole display is black. "Check Engine" sign blinked briefly. Battery display shows the battery is "green". Everything else works - cd/radio/bluetooth, etc. As I tried to start it, the screen showed that the engine briefly charged the Prius battery, then it was all quite. I tried to wait and restart a few times, but still the display was all black and no "ready" sign. I WAS able to still move the car, but I didn't chance to drive it out of the garage. I just had it serviced (oil/fluid change). Small battery was replaced in July.
