Let’s say I have a problem with the starter motor, or the buttery is too weak, how can I start the engine by towing or just letting the car go downhill? Of course, we are speaking about a manual one. |

Managed to do it in reverse with a Peugeot 504. Could not get the starter motor to work.

I have done it myself with many cars but with freelander 2 it’s not working. It seems that there is a conflict with various sensors and switches. In order for the engine to start, it has to rotate with enough speed and the clutch has to be pressed. |

Surely the clutch has to be pressed just for the starter motor to work? By that reckoning, you are saying that the car can't be tow started. Are you pressing and holding the start button first without the clutch depressed to turn on the ignition? |

Yes! By pressing and holding the start button for 2 seconds the ignition turns on. |

Without pressing the clutch. |

Ok sounds like it isn't possible. If the starter motor is sticking try rocking back and forwards in first gear, or hitting the starter motor with a wooden mallet (not sure how easy that would be). If the car then starts, it is the starter motor which needs replacing. If your battery goes flat after a few goes then it is your battery. |

I was always taught as an apprentice to not bump a diesel due to the high compression in the engine causing damage to the transmission.

I checed the battery is good. Anyway, sometimes it starts some time it does not. I can hear the solenoid when I push the start button. By having someone in the car (to push the start button) an me hitting the the starter with a hummer always start's. Obviously is the starter the problem. The issue here is how we can start the engine by running downhill. I think the ECU is not leaving it to start. Or maybee is just a switch on the clutch that has to close contacts without pressing the clutch (somehow). |

Why not change the starter motor? |

I think you are right. I have tried various combinations in the past but been unable to get the engine to fire up on a hill. |

Do not try & bump start what ever you do unless you fancy snapping the timing belt. |
