Evening guys, i'm new to this site so please be kind!
I have an S-Line A4 2008. On Friday the flashing coil light came on and went into limp mode. After turning the car off re-starting the car the light had gone out. I had a range of 255 miles left in the tank. Basically upon driving the car for every mile i did i lost 5 miles on the fuel tank. Took it in to my mechanic today, he did full service including all filters changed new oil etc, did the MOT and put it on the diagnostic machine. This threw up lots of faults. He dealt with them all, put it back on the diagnostic machine no faults coming up. I got the car back put diesel in (£60) which gave me a fuel range of 370 miles. Ive done 4 miles of driving and fuel range dropped again to 350 miles. He said he checked injectors and they seem fine, no black smoke coming out which also would suggest not injectors.
Guys I'm at a loss so is he, anyone got any ideas?
Thank you
