      I have been trying to recalibrate my fuel gauge. It is very non linear. I have read that calibration errors are cumulative. The top ˝ of the tank gets around 220 miles and the bottom half gets more like 180. I know this is a very common complaint.
      In any case, I have seen write-up on recalibrating via adaption. The write ups I have seen mention changing the stored value from between 120 and 136 with 120 being the default value. I think this was for MK IV cars.
      On my car, when I get to the adaption channel, I see the screen attached. As you can see the value is 0.0 in what looks like degrees.
      Rather than just try a new value of let’s say .9 degrees. I am hoping someone can explain the adaption values .

      The general idea behind this correction was to have the reserve limit properly set and not necessarily if the gauge shows "full" or like in this case that one half is actually more than the other half. So even though the values to input have changed the actual idea behind it hasn't and from what I read the thing you want to get done is IMO not possible because VW hasn't designed this mechanism to accomplish what you are looking for.

      Sebastian,

      Thanks for your comments. I agree that VW never intended to use this adaption to correct a non linear fuel gauge but it is so annoying to have a otherwise precisely engineered car be so sloppy in displaying fuel level. In any case I don't mind experiment a bit to come up with a fix especially because I have heard a lot of VWs have this problem. I have done a lot of tweaks with my VCDS but I am hesitant to change this adaption value without knowing more about it.
      Do you know the outside high and low values or anything more about the procedure?

      What you've got there is a cluster which uses the brand-new UDS protocol; we have effectively zero documentation for those, aside from what's already incorporated in VCDS. So at present, we are not able to explain the adaptation values.

      It's possible Dana might be willing to play with this channel in her car 2010 GTI to see how it reacts, but she has the rest of the week off.

      Uwe,

      Thanks for the reply. If Dana could poke around I would appreciate any insight she could give. I'd be happy to experiment with different settings as well to further the documentation but don't want to do anything that's not reversible.

      On another note, I sent in my auto scan and label files to Sebastian. Are there are any other scans or tweaks I could try to further the documentation of other modules? I would be glad to help out with that as well. So far I have enabled coming home, key fob widow operation, enabled all doors unlock with one remote press and changed the comfort lane change to 4 flashes.

      To clarify, it seems that the 2010 Jetta Wolfsburg is a transitional model. Is my car a MkV with some of the modules updated? Sort of a MKV.5 ? I know that module 46 functions have been merged into module 9 for instance. Is there a list of what modules are the same as previous MkVs and which are different?

      The electronics in that car are essentially "Mk.6".

      Of course the Mk.6 isn't an all-new platform like the Mk.5 was in any case..

      Hi Chris. We have not received many questions or much feedback on this. I will play with this and see what happens, but it may take a week or so of normal driving to determine what the effects of the fuel gauge and / or correction of consumption really do. Feel free to shoot us an email if I don't update this within that amount of time.

      I've done some testing on a '10 Gti. The Instrument cluster adaptation results are:

      "Display correction of consumptions and operating range" found in Adaptation, from the instrument cluster. The value should be 100% from the factory.

      Increasing the adaptation value lowered the Mpg data displayed on the MFA. So, If you want to lower the average MPG displayed on the dash, try increasing the adaptation value to 102% -> 105%.

      If you wanted to Increase the Mpg on the display, lower the Adaptation value to 95% -> 98%.

      ---

      "Display correction of fuel gauge" found in Adaptation, from the instrument cluster.

      By default, this was set to 0.0*. The Max adaptation values are +/- 10. The total range of fuel gauge movement was near 1/8th tank.

      Increasing the value to 10*, makes the needle raise by approx. 1/16th tank.
      Lowering the value to -10*, makes the needle lower by approx. 1/16th tank.

      I dug into this and believe that the sender in the tank has a normal operation range of 70Ω -> 270Ω.

      A Full tank should read near 70Ω. Empty tank = 270Ω. You could check the actual resistance with a DVOM at the fuel level sensor in the tank -OR- By using Advanced Measuring Values, check "Fuel Level Sensor 1" (138).

      ---

      However, I don't think any adaptation modifications are going to correct your concern. If you change the correction of fuel gauge, the actual needle range may become corrupted. After filling up, the tank may not read full, or worse..the empty tank range may not read correctly resulting in the vehicle running out of fuel.

      It's possible that the fuel level sensor "G" is faulty. I really haven't noticed any issues with mine. The car only gets 27Mpg, so I don't stress myself out by monitoring this. It displays "Please Refuel" and I find myself filling the tank quite often!

      Dana,

      Thanks for the detailed explanation. I have no problem tweaking and making empirical observations to zero in a solution. My concern is over your use of the word corrupted. Do you mean a temporary non accuracy in the gauge as to not reading full or empty at the right time or do you mean permanently adapted to a value where it will never read full or empty accurately? I'll look at the advanced measuring values as you describe to try and determine if there is a problem with the sender. I have searched this problem and it's fairly common on this car. Just like it's fairly common for 1.8T's to eat coils. My point being I would love to not only fix my problem but possibly uncover a faulty design that's endemic.

      BTW I get 27 mpg as well. I drive a lot of highway, but at a fairly high speed. I have the DSG. My tailpipe is black with soot. I have never had a fuel injected car blacken the tailpipe like this. Do you feel like there may be a link between fuel mileage being somewhat low and the sooty-ness?

      Chris

      Chris,

      I meant corrupted in a temporary, calibration way. If I was to edit that, I would use "Out of Calibration" instead.

      I don't think any damage could occur unless... You had a full tank of fuel and the gauge was also reading full, going into adaptation and increasing this to a larger value could peg the needle and possibly cause damage. I suppose the same could apply if the vehicle was completely out of fuel and you attempted to decrease the value beyond empty.

      The Old School fuel gauge reading adaptation procedure (MK4/B5 style) was to remove all fuel from the tank. Add 7 to 9 Liters of fuel to the tank, depending on the "Reserve" level as per the repair and owner's manual. Set the adaptation of the fuel gauge within the middle of the Red graduations. After the fuel gauge was calibrated, there was a MFI procedure which had an adjustment range of 85% - 115% and I do not remember which way was +/-.

      --

      I also have the DSG in a 4 Door Gti, 18" wheels, etc. I will say that it's not a light weight in comparison to my '02 1.8T Manual trans. Gti at 33.+ MPG.

      The tail pipes do soot up quickly on the new car but I haven't had the emissions actually checked. PA dropped the tailpipe test on 1996 (OBD-II) and newer cars in 2004. Having the old IM testing equipment is very rare around here. I would say less than half of the local shops still have one..and I might look like a fool requesting a tail pipe test on a 2010.

      I wonder what the Mpg will do after chipping. Waterfest is coming up soon, which means show special pricing.

      I seem to be about 8% high on my mileage readings (compared to hand figuring) and tried to correct it by doing the steps listed above. 17 Instruments/adaptation-10/display correction of consumtions and operating range/new value 105, new-old value screen/ uninitulized controller warning/ check yes/workshop identifcation error / OK/ value out of range............. I tried different values from .01 to five, I even tried minus values with no better results. I am sure it is my rookieness in using VCDS so what is my next step. So what should the workshop identifacation by?
