Good afternoon, My car after running 2.000km perfectly, sudenly do not start... i have searched but did not find nothing similar... The only thing that change from "before" is that when i turn the key and normally all the slow down lights (2) and check engine light lights and after 2 secs the check engine goes off and after starting the slow down lighgts goes off. Now when i turn on the key, only slow down 1-4 and check engine 1-4 lights and after 2 sec the check engine go off. but the 5-8 lights do not light (they have bulbs ant tested them...) I looked at the fuse and relays and all seems to be ok.... Any idea of the problem? thanks
I would start with checking that you're: a) Getting air (check that the entire path from inlet to throttle body is clean, unobstructed, and without leaks) b) Getting fuel (can you hear the fuel pump? are the fuel injectors all making a clicking sound?) c) Getting spark (pull the wires and check the arc at each. Use a spray bottle and check for "leaks" along the wires in low light) This should get you heading in the right direction.
The warning lights for only one bank now light up? Sounds as though a fuse, relay or DME for the 5-8 is not functioning correctly.
Juan, I've just had a look at the wiring diagram with your description in mind, I would look at Relays 'c' (terminal 86) and 'd' (terminal 87) located in the passenger footwell electrical panel. The above 2 relays have interaction with the following services/systems (plus other areas I'm sure): Connector Motronic 5-8 to dashboard Airflow meter 5-8 Motronic ECU 5-8 Compensation control electrovalve Exhaust Temp high warning lamp 5-8 Each of the bank 5-8 injectors (pin 2)
