    Accuracy of onboard tyre pressure measurements?

    My tyres should be at 255kPa or 36.99 psi Digital pump on petrol station forecourt is set to 2.55 bar (=255kPa) so all 4 tyres should be at 2.55 bar or 255kPa The car's own electronic reading shows Front NS = 270 Front OS = 265 Rear NS = 263 Rear OS = 255 Not overly...

    Comand Accuracy ?

    Im using an NTG1 with 07/08 maps. I find it a real pain the wotsit to use. I set it to take me to a town the other night , I knew about 90% of the route anyway as Ive been before but thought Id give Comand a shot at it. It took me a really roundabout way , I think it added about 25 mins onto the...

    Speed/mpg/range accuracy.

    The computer display in both my cars is about 5% optimistic. Not a problem, as I know the accuracy. In previous BMWs I've owned you could enter a correction factor, and correct the readings. Is this possible in MB's?

    Trip computer mpg accuracy

    Here are my findings after seven months and over 13k miles. At each re-fuelling, which tends to be from nearly empty to completely full, I record the "From reset" mpg figure and reset the computer. On average, the computer reads about 2mpg better than actual.

    w124 Fuel Gauge Accuracy

    Or lack of it. Just filled the tank to the point it was coming out and says it's 3/4's full. When I bought the car it ran out on the A1 with 1/6 tank still showing. No reserve light... If I drive somewhere the gauge doesn't move much or at all. If I turn the ignition on and off it will then...

    Trip computer accuracy

    Top Gear mag. has a long-term W204 C220 CDI, which they think is fantastic. Interested to see though that they reckon the trip computer is a rather optimistic. Over 2,371 miles their fuel added/distance covered calculation gave 36.3 MPG, whereas the trip computer said 38.8 MPG (nearly 7% out).

    Trip Accuracy

    How accurate are MB trip computers in reporting fuel consumption and range? I'm reckoning it's over optimistic by about 10% on consumption on my W211 but I haven't had enough time to do any decent averaging as yet. (The only other car I've had with an mpg readout was a Honda and that usually...

    E Class W211: Fuel gauge accuracy

    Since picking up my car a month ago, I've noticed that the fuel level reported by the fuel gauge tends to be quite sporadic. In the morning it can give the "Reserve Fuel" message accompanied by the yellow light, then when I come to drive it home from work at night, the message has gone along...
