Hi new to the club as this problem brought me here
Have a 2008 b8 a4 tdi 140
Was driving the otherday n seemed lik went into limp mode cldnt get above 45 mph pulled in at a shop as soon as noticed it someone said it was smoking white so i thought injectors or turbo , wen i came out of shop to start it it just wouldnt start and a battery light came up saying it would charge when driving. Had to get it towed, plugged it in wen got home n turbo underboost n starter malfunction came up few othercodes unrelated, car sat up for a week n went to start it n just clicked i put jump pack on it n it seemed to crank once then just clicks. Starter code came up but wondering is that cuz battery died n wasnt coded out
dont wanna go buy parts i dont need any help appreciated thanks
