The fuel gauge on my 2012 M3W was never very accurate but recently, it has started to go totally Boris Johnson (tells fibs and makes no sense at all). Today it was reading 11%, so I called in at a filling station. I managed to get 5½ litres in, in spite of much side to side shaking to equalise levels between the two tanks and much topping up of tiny amounts. The reading went briefly up to 80% but after just 15km driving, it is down to 49%. I am wondering if the breather tube for one tank has become kinked or blocked? It seemed worse when I got the car back from its total rebuild at Malvern but since has become even more illogical.
Any thoughts folks? Change the sender?
