Passat (B5) :: MFA Readout Screen (Dashboard)
Dec 8, 2006
I have a 2000 Passat. Have any of you had an issue with you MFA unit. My red screen (which reads out the trip mileage/fuel mileage) has had a long term problem. My screen is gradually losing the red lines (LED).
I had one line burn out and now a second red line in the screen will not light up. In essence, my screen is gradually losing lit lines on the screen. I had this problem when I first bought my car new. I had the entire MFA unit replaced due to this issue under warranty. However, the replaced screen is now exhibiting the same problem.

We've only had the car for a week but I'm puzzled by what I'm seeing for the mpg on the screen. At no time has the screen indicated an average mpg of outside the range of 44.7 to 45.0 mpg. This is despite filling it up, resetting the trip meters and immediately heading up the Cajon Pass twice while the instant fuel economy indicated 25 mpg or less. I understand the inconsistency of calculating at the pump because of the bladder but doing that has worked out to 2 fills in the high 30s, one in the high 40s and one of 53 mpg. Yet the car still reads 44.7 to 45.0.
It's not a big thing because I don't depend on it; I tend to fill the car when it goes below 1/2 full and over time I will have enough pump calculations to give me a fairly accurate depiction of my average mpg.

How accurate is the mpg readout on that display screen on the Prius. How is it measured.

I have had this since the day I bought my car. When the tempurature outside is hot, the screen on my R dash is dimmed, almost like a cirlcle around, and every some often (has only happened twoce) I turn the car on and the screen doesn't even come on, it's just blank. Just wondering. I think I jut have to have it replace and all, but it could be something....

Out of the blue the main screen started to flash. "Synergy hybrid drive" logo shows up, then screen goes off (every 1-2 seconds). I've searched prius chat/google and could not find any useful info.

I own a 2005 RX330 and all my dashboard is cracked. The model I have is the one with the simple clock screen. To replace my cracked dashboard, I found to the scrapyard a RX330 but instead of the simply clock, it has a GPS screen, I would like to know if it's possible to install this screen on my Lexus? The GPS will be functional? Below two links, first one is the kind of screen I have and second one is the kind of screen I would like to install : [URL] .....

My 2010 Santa Fe has some transmission issues.
Now and then I notice the vehicle is kind of slow and every now and then when going from P to R, or R to D, it enters with a bang and after that the Gear indication in the dashboard disappears. At that moment the car is completely sluggish, like if it is some kind of lock mode. I have to turn it off and on again and all is back to normal, however, after an episode that it enters with a bang the transmission doesn't react as well as normally, it takes a while for the car to behave normal again.
The fact that the gear indicator disappears from the screen on the dashboard suggests to me that this is a computer problem more than a mechanical issue.

I have a 2009 camry SE 4 cylinder and cannot find my mpg readout anywhere. I looked in my owners manual and what that read does not exist in my car. Maybe there is no mpg readout?

I am interested in having an MPG readout on my back bumper, maybe next to the tag. Nothing large and in your face, but something someone might notice as they cruised along behind or next to me. So that might even mean dynamic brightness to prevent people from being blinded at night, or it being a distraction.

Is there a digital readout gas gauge so that when I am driving down the road I can see exactly how much fuel is in the tank

I was driving in the sun the other day and realized I can't read my orange information center section of the instrument cluster during the bright day.
Is this normal? It seems dull.
I saw some bulbs for the instrument cluster here:
Would these be a replacement that would fix the issue or is the orange section not using a bulb at all?

I have a 2013 Corolla S. I notice when I let the car idle for like 5-10 minutes the Average mpg readout drops to around 22 mpg(in city while driving it is usually at 25). Why is this?

We have noticed something strange with the dash in our new 2012 Prius. While driving at dusk and turning the headlights on the dash readout can go completely dark. Leaving only the gear selection indicator visible. This can be completely disorienting and dangerous. This happens if the dimmer wheel is set in the lowest position. It will turn back on if the dimmer wheel is moved up from the lowest setting.
I can recreate the issue parked by simply having the headlights on and dimming the switch all the way down. It will shut off the speedometer, MPGmeter, and Hyrbrid indicator screens.

This truck has been a good running truck until recently..... lately you can drive for awhile then the check engine light comes on... readout says reduce engine power.... if you stop for like 30 seconds or less and restart all is fine. It doesn't do this all the time or every time has done it once a day or 4 times in a row, never a rhyme or reason to it. I have used my computer reader to see if i can find the problem myself but for some reason the reader can't read ( still trying to trace why.... even the free scan from oreillys couldn't link to my onboard computer for some reason) so the problem to the onboard computer not linking to any reader?

My outside temp readout seems to be stuck at 61-64 degrees and that won't allow the auto select to come on if I have it set at say 72 degrees. It has been working really great up till about a week ago.

We have an 04 GX-470. Most of the time the fuel gauge and the range readout work OK. However, sometimes, the fuel gauge works, but the range shows 0 miles, or they both don't work - fuel gauge shows empty and range = 0. My wife says she thinks she's seen the gauge = empty but the range still showing xxx miles - I haven't seen that.
We've been to 2 different Lexus dealers, paid for diagnostics at both and gotten no fix. In fact, they have both said they can't find anything wrong.
To my way of thinking, these would both get their initial information from the same source - some sort of sender unit on the fuel tank. However, as both gauges do not always go out together, I'm inclined to think that this probably isn't the cause. I would think that the range readout comes from some calculations done by the onboard computer.

I already searched and seemed to only find info about, no backlight but lcd readout was still working. My backlight reacts to the lights being turned off and on; so I know it works but just no numbers. I noticed it on the way to work after the truck had been sitting in the hot sun for a while but When I got off work after dark around 11:00pm it worked all the way on the drive home, but I went to grab a bite and it no longer worked. I figure it could have something to do with sitting in the heat? It's the stx cluster with only the speedo and no tac if that makes a difference. I really don't want to have to drop cash on a new cluster.

This morning when I started my SE -> both my key-fobs showed Low Battery on the MFi screen. Yes I know they are covered within the 12 months warranty but surely 3 months of use should not deplete the batteries...

1997 Ford F250 4x4 HD ... My vehicle has about 197,000 miles on it and for the most part still functions properly. I do have an odd "happening" sometimes and here is a description:
I will be driving along and all of a sudden the digital odometer readout will go blank and the speedometer will drop to 0 if I was going 60 mph or below or to 120 if I was going over 60 mph.
Where do I start troubleshooting?
