Tried to start my 300tdi today( m reg used for moving trailers and towing up steep track, not on road) but battery low just turning over. Change battery but then would not turn over.(new battery ok) The alarm/imobilizier which i think is a aftermarket one (laserline) has a override switch righthand side of steering wheel was flashing and would not reset. Then reset but still not turn over. Checked earths all ok. Took switch wire to starter motor off, no volts. tried a wire across the starter motor and turns over. It a early 300tdi, it has a red led light under the radio. When i bought it he said the laserline alarm was a aftermarket alarm. Removed the lazerline alarm and connect the one wire which had been split into the alarm which was the white wire to the ignition switch. rest of wire were just spliced in. Still no joy. when turning the key to start a solenoid (right handside of accelerator pedal) operates and the ecu passenger side clicks aswell.but still no joy. Looked in workshop manual. i think the solenoid next to right foot is the starter solenoid (tried another solenoid item 4 in manual) but still no joy
Can any one help as the snow is coming and i really need it.
