B7 08 A4 S-Line Avant 2.0tdi.
Used it last Saturday and did a fair bit of mileage. Used it Tuesday night and drove about 1 mile, drove back the same distance later but with the lights on.
Same trip Thursday night. Came to drive it Saturday and it cranked too slow to start, fired up fine after a jump start and drove a total of around 50 miles during the day with shopping and all that. Other than Tuesday and Thursday nights low milage it just sat outside.
Yesterday morning it started fine, drove for 200 miles and when I came to come back 200 it started no problem
Do you think the failure to start is down to the battery not getting enough charge when I used it during the week, or could it be something more sinister?
