2013 A3 salloon Electrical fault

[Scoot_McGoot]

Hi I have 2013 A3 Saloon 2.0ltr TDI 150 Sport, ive only owned it for just more than a month and all of a sudden i got a warning message come up on dash and all my driver convenience systems have started to fail.

I get a TPMS, Hill start Assist, Auto wipers, Stability control, traction control, ABS and headlight range system control light warning messages all saying they have a failure. I have it booked into a specialist garage near my work but they can't see me for another 2 weeks, just wondering by chance if anyone else has had this issue before and if it was an easy fix?.

If you suddenly have a ‘Christmas tree lights’ with multiple errors - check your car battery as it may be at the end of its life / significantly discharged.

Do they go away after a short drive?

@JohnM100 I have a 15 mile drive in the mornings and back home they do not go away unfortunately, would you suggest swapping the battery out? I may have a spare one that fits my car but will have to check.

To second John's thoughts, these are exactly the symptoms I experienced when my battery was on the way out. When you change the battery, be prepared for some systems to take a while to come back online. I think it took about 20 mins of driving before my Stop/Start warning vanished.
