what a nightmare...car sometime cant start or een crank..then it start normaly engine run fine sudenly all pointers in dash falls down..in diag there is a lot of errors in every moduls..so I yust delete all..next time it starts and after 5 minutes I lost comm with engine..when there is no comm with engine dash is almost dead..OK all data goes from engine thru CAN..so trace CAN lines from engine...manage to find small CAN junction box behind glowbox...green and green/white ...If comunication with diag is broken car cant start ...so OK ignition lock conected to engine ecu and dash via CAN line...
what do you folks can say..is it engine ECU main suspect or I need more inestigation to make..
