I have a new factory built R500, which I collected just before Christmas, it has been back twice for CC to calibrate the fuel guage, but it is still reading incorrectly. I was told it was an ECU upgrade issue, which they said had been sorted but obviously not.
My old R400 stack dash read quite accurately at 36ltrs when full this one only reads 29ltrs and the fuel low warning light comes on at 9ltres.
Has anyone else had the same problem, is it still ongoing or did you manage to rectify it? If it is simply a case of adding 5/6ltrs to the read out figure I could live with that, but I'm just not sure if the calibration changes as the fuel level decreases.
It is frustrating as the car cost so much and I dont want to keep having to give it back, they have just had it for the last month sorting out a gearbox oil leak, armourfend issues and fuel guage.
Any ideas anyone?
