Hi looking to find the altitude sensor on a 190E 89/90 model, I am told its behind the battery but had a good look around unable to locate. Fault code 8 comes up on diagnostic running rich. Car was originally just shutting down when driving all lights on dash come on, no power just silence. Found faulty distibutor cap and leaking fuel component, mechanic now at a loss to locate this altitude sensor . Can someone please help with this situation, perhaps a diagram or photo with location would be great. Many thanks in advance.
