Hi all again. I have been working on a Mercedes A Class A160 2000. The customer rang up to say that it would not start after leaving it parked up for four hours. I went and checked to find that when key was turned the display read "start error". I removed floor panel to access battery and fuses. Tested and found battery to be at 12.5 Volts. Windows lights and central locking is all working. When I plugged in diagnostics I recorded 18 fault codes. I disconnected the battery terminal and refitted, turned the key and it would start but go into limp mode. The throttle pedal would not respond. I have tried his spare key and operated the immobilizer in glove box but still not starting.
One thing I did find was with data on my diagnostics the battery would show only 8 Volts. If I disconnect the coil pack then it would read 12 Volts is this correct? I have also removed the battery to recharge and test, only to find a plug connector with two wires ( purple white and Blue) The blue wire was corroded and broken. At first I thought that this was the fault. Repaired but still the same. The chassis No on this vehicle is WDB1680332J453425. ECU part No A166 150 03 79
Here is a list of the fault codes.
P0320 Ignition output stage cylinder 2 and 3 stored code
P0600CAN from electronic stability program (ESP)stored code
P0100 Hot film mass airflow sensor bank 2/5 spor fault stored code
P1176 B40 oil sensor stored code
P0230 Fuel pump release module K27 open/short circuit current code
P0443 Canister purge (Y58/1) open circuit/short to ground current code
P1673 CAN fault M4/3 Fan short to ground current code
P0201 Injector cylinder 1 Y62Y1 open circuit/short to battery negative current code
P0202 injector cylinder 2 Y62Y2 open circuit/short to battery negative current code
P0203 injector cylinder 3 Y62Y3 open circuit/short to battery negative current code
P0204 injector cylinder 4 Y62Y4 open circuit/short to battery negative current code
P0230 Fuel pump release module K27 open/short circuit current code
P1590 Safety fuel shut off detected current code
P0120 B37 ped sensor 1 correleation sensor 1/2 stored code
