Im sure someone else had this issue and it was a pressure switch/ solonoid , short in the switch in the Haldex unit. Seem to remember dealer wanted hours to diagnose and suspected it was a wiring issue but it was just the switch/sensor |

mine showed a HDC fault when the battery went flat due to the glove box light switch falling out of it mounting. That meant the light stayed on and because there was a light on the on board computer stayed on and drained the battery.

It's an insane world when you are charged £200+ to get a dealer to plug into a computer which tells then exactly where the fault is so that they can have an opportunity to quote for work!

thats why I bought a code reader costs about £20 and you can look up the codes on google to see what they mean |

cheap code readers are only for EOBD thats "europeon on board diagnostics". basically emission related issues only.

I had a similar experience. Take a look at http://www.freel2.com/forum/topic11513.html which may help.

Sorry to hear of your problems. You asked about independants. I can recomend Pete Broom at Beacon Garage, he has sorted any problems I had with both my Defenders and FL2s as well as my brother in laws RR.

Simple thing have you checked all the lights (side main beam brake etc) reason I ask you normally get HDC fault and lowering suspension on D3 with a blown bulb, I know freelander2 does not have multi height suspension but worth a look first this happened to my D3 and is quiet common on them, might save you a few pounds.
