    Hi, just accidentally started car after sitting 2 weeks in gear and now it wont turn over. Doesn't sound like a battery problem or any faults on dash just wont turn over at all. Cars a 2006 2.0 TDI S Line A3

    Any Ideas as need to get it going asap?

    Sounds a bit like one of the following: bad battery,loose battery connections,blown fuses,broken earth strap/loose,seized /faulty starter motor ,faulty relay and blown fuse.

    i would jump start first off and then get a multimeter and a mallet for the starter

    If it was turning over constantly but not starting possibly but if it's not turning over I would start with what makes it turn over and as a jump start is an easy way to rule out the battery.

    start with the basics to rule them out

    You've had it tested?


    Get someone to check the cranking speed with VCDS by unplugging the main loom into the engine, it will struggle to start if less than 280rpm iirc - that would still lead back to battery, starter motor battery leads....
