Hello all. I've got a 2015 Audi A3 e-tron and it's just started to develop a "judder" as I'm driving along. At first I thought it was an intermittent fault, but then I noticed it happened as soon as I went over the 30% power range, i.e. out of the "efficient" area of the gauge. Does anyone know what the car does differently in the efficiency range that could explain the judder? Does it engage a reduced number of cylinders and therefore it cold be the coil or spark plugs in the reserve cylinders?
Thanks in advance.
