A3 1.6 diesel all warning lights on

[tim01]

Could anyone please help,  parked up last night all was well,  this morning started car reversed out then all warning lights came on , car drives but went to turn off and it kept running for a few seconds,  then went to start it and it wouldn't start but when I released the key it kept turning over until I turned key completely off and removed from ignition,  then it started fine next time but all warning lights are on . Anyone point me in the right direction of where to start looking please.

Welcome Tim.

First thing to eliminate is the battery.

Suggest getting its efficiency check - Halfords stores will do that. 
If it tests substandard then please refer back to us before committing to buy - if you have any respect for your wallet. 
Kind regards,

Gareth.

Thank you,  I done this today and its fine, I tried scanning it but it gives no codes at all, in the display it firstly says TPMS then says brakes faulty which I have checked as best I can,  brakes work well, I should have said its automatic transmission,  if that makes a difference,
