My audi A4 2010 1.8T
my audi A4 2010 1.8T wont be on. all dashboard lights off, does not start even
to crank. headlights and indicators working fine, even central locking is working
just fine. replaced the battery, checked some fuses and relays but all seem to
be fine. please, what could be the problem. all this started a week after the
engines was washed with water pressure pump and engine cleaner.
