The battery health test was done at halfords, so not sure what kit they use to test and with it being that cold at the minute im not really keen to be standing outside testing.
I did recently buy a AUTOOL x60 Car hud. I've been driving with it for about 2 weeks now and the ave MPG is 28mpg. my recent driving has been with empty back and just roof tubes and 2 trips a day of 80miles each way on 97% motorways (70mph). the live MPG data tho will fluctuate between 6mpg and 60mpg while driving, although it tends to manly be between 35mpg and 50mpg.
Could a sensor be an issue?
Im not 100% convinced on the AUTOOL unit, it says 100miles after a 73mile drive and i havent checked if there is a setting to fix. there is a speed one tho.
