My 1997 Audi A6 wagon has just started to overheat within 5 miles, with the oil temp gauge going to red and white steam/smoke coming out the AC/heat vents. Coolant disappears quickly. I fear an engine fire. Any similar experiences? Fix or scuttle?
Oil temperature gauge?
Is the coolant leaking onto the ground or boiling over, of does it just disappear?
You could have a simple problem like a stuck thermostat, which is inexpensive to replace, or you could have a much more serious problem.
I suggest you have the vehicle delivered to a mechanic on a roll-back car carrier. Driving it will only make matters worse.
