Hello together I’m new here and for a short time owner of a 850 lw 2.5 20v from 11.95 have found that my abs and tracs are completely without function all contollamps don’t shine on even when igniting can it be that the previous owner has manipulated something to cover up a mistake or can it lie on the relay or control unit? and where exactly are the two sitting? for quick help I would be very grateful to you.
