I have a 2007 Volvo Fm7 truck that goes into limp mode. Computer says to check transmission and check engine.
used to be able to wait 15 mins then off she would go again, but has progressively got worse to the point where you would have all dash lights but nothing when you turn the key. We have changed the relays and whole cluster as they get hot but dont smoke. to no avail. when we changed the whole cluster in the dash she went for 600klms before going into Limp mode again. Aparently it had 61 codes come up on a computer but then ole mate didnt want to do anything about it or give us the codes. Anyone else had this problem
