D4 rear ended will not start.

[Bohica]

Out with some Land Rovers. A D4 was rear ended and will not start. What can we do? No nanocom or Hawkeye or any of that.
Another car D4 will start but is sitting on its springs. Air springs fully down. Again any ideas?

Try a hard reset for the 2nd D4?

Hope you get them going...

The d3 has it as part of the srs system, signals engine ECU etc when airbag or pretensioner is activated. No user resetable switch like the d2

Knowing what happened to the D4 on its bump-stops just before it went down might be helpful with a solution.

The d4 on the bumps stops was doing nothing. Waiting for recovery for the D4 and deefer 90. Unimog on the way about 90 mins ago.

Sounds an unfortunate end to the day.....

Hope the recovery goes well

Sadly no technical help from me.

[Bohica]

Unimog left the track and was safely recovered. Deefer 90 recovered last night. Back today for the D4

[Graeme]

If extreme off-road conditions then perhaps the D4 on the bump-stops' problem is damage to the compressor or wiring or main air-line which has triggered the bump-stop condition.

Bohica. Any update on what might have caused the rear ended vehicle to refuse to start?
