OK, so apparently a shop my car was at thinks my car IS currently running some sort of software, now as far as i know, it wasnt. Now how would i go about checking if it is? All i have is the cheap 15.00 ebay vag-com cable, i heard you cannot recode with these?
do i need to actually take some things apart and look at it? is there software i can run?
