Limp home mode on a Disco 2

Recommended Posts

Recently my 2003 Disco TD5 has occasionally shown the 2 green lights on the dash blinking (limp home mode) when I reverse and then switch to drive.  They reset immediately if i stop and start the engine.  

When this happened a few years ago it was as a result of the sender on the accellerator being faulty and replacing it cured it fully.

Occasionally it happens when I try to start the car and it dies.  If i retry a couple of times it blinks  .....Bye the Wa I think the engine dies due to the engine ECU not reading the key correctly.  The fix I have come across for that problem is to get out of the car and shut the door hard and set the alarm.  Then start all over again.  Sometimes it needs 2 trys to work but never let me down yet.

Anyhow ............anyone got any suggestions as to what sort of gremlin is living behind the green lights on the dash?

The flashing M&S lights can be caused by any electrical faults.

Low battery voltage, bad/loose connections to battery, xyz switch going bad, alternator going bad...

Get the fault codes read so you can narrow down the problem.
