    MID is usually more than tankful to tankful by about 5-7%. In 99% cases I get it this way. However, on rare occasions, MID shows sometime about 2 kms lower than tankful to tankful. Those can be termed exception & could be due to variations in tankful in 2 consecutive fillings or fuel quality or may be the bunk gave lesser fuel than what shows in its meter.

    I doubt.. normally GPS during running motion gives accurate figures. And its good that speedo is showing more than actual. Anyways.. I would not comment on this.. else this will go on :punch . I would suggest FIAT to give in build GPS navigation with GP and Linea as stock. Let them charge 10K extra, people would be much happy.

    AC Compressor Relay

    If you feel that cranking takes a few fractions of second more & the message "airbag failure, pls check owner's handbook" flashes on MID, get AC Compressor relay checked. This message occurs when there is not enough current to run Diagnostic checks as Vijay mentioned. AC Compressor relay is located in in a Fuse Box near the battery on the right hand side. The bottom most fuse-like plug-like relay is AC Compressor relay. The symptoms of AC Compressor relay going kaput are...

    • "tak" noise (like a swaitch is toggling) when you disconnect -ver terminal of Battery OR
    • "tak" noise when you plug out & plug in the faulty relay.

    If this relay has conked off, it does not cut off AC Compressor even when you turn off the engine & remove the key. Compressor continues to drain power from battery & the battery will drain in short time.

    Hi,

    I tried to find out but not a luck to get it. As an invented feature for Punto E+ has ready-made rear AC vents, which are described by our friend VahanPujari in http://www.teamfiat.co.in/fiat-oem-spares/2870-fiat-punto-linea-spare-part-price-part-number-no-queries-please.html thread. So, if I fit Linea armrest, with rare AC vent ( Part NO 0735494410), can I get the fully working AC line Linea in my Punto?

    While reading in some forums, the feature is only available in E+ ( I am not talking about rare vents below front seats, but the one which will throw cool / hot air from the vent)

    Please guide as I am planning to mod it during first service.

    Anyway, Pandit Auto, Pune don't know about this. Even they don't know about teamfiat.co.in.

    Thanks,
    Prasen

    I too have noticed this error when using GPS of MMI as well as two different Samsung Android phones. What I have found is the difference to be almost 10%, which is not very noticeable at speeds below 40kmph. But this 10% difference is very clear at higher speeds and the maximum I have taken it to - speedo showing 160kph, GPS shows 145kph.

    Coming to accuracy, there is a legal requirement in US and probably EU as well, that at no point in time shall the speedo of a vehicle show a value less than the actual speed of the vehicle. The regulations doesn't specify an upper limit for error, so all vehicle manufacturers make those devices to show a higher value. So the vehicle speedo will always show a higher than real value. The degree of error can vary from brand to brand, but is typically around 5-8%

    i have done the same in my linea. you will need the ducts to connect the front to the rear. plus it is not a flush fit so have to make some adjustments so that the air does not leak. am attaching the pics of the ducts.

    This is what wiki says:

    Most speedometers have tolerances of some ±10%, mainly due to variations in tire diameter. Sources of error due to tire diameter variations are wear, temperature, pressure, vehicle load, and nominal tire size. Vehicle manufacturers usually calibrate speedometers to read high by an amount equal to the average error, to ensure that their speedometers never indicate a lower speed than the actual speed of the vehicle, to ensure they are not liable for drivers violating speed limits.

    GPS, unless assisted by AGPS will have positional errors and can induce fixing errors. Most smartphones nowadays are agps assisted so error is negligible.

    I own a 1.3 GP MJD E+, and recently I was driving it with front and rear fog light on along with low beam of headlight. I switched off only the headlight when I parked it. Later when I turned on the headlights, the fog lights were not automatically switched on. To me, its a big plus point. I don't have to worry about the fog lamps..they are off when all the lights are off. If I just turn off the headlight and parking is on, the fog lamps are on.
