Thanks for all the info Dave,
Well at the moment it doesn't have a VCU or IRD but part of the deal when I bought it was that he will fit these (reconditioned units) when I take it in next week. He also guaranteed everything working and he will fix anything I find wrong with it then aswell. Not having this wouldn't cause the ABS light not to work would it?
I beg to differ. If you are driving the car then it must have an IRD. Without the IRD you have no front differential or rear power transfer gear train. The front drive shafts would have nothing to connect to, oh and all the oil would fall out of the main gearbox. Nothing too drastic really.
Its possible for the VCU and the associated central prop shafts to be missing and it still be driveable, all be it front wheel drive only. Check under the car. There should be a central shaft assembly with a circular assembling half way along its lenght (This is the VCU) that is positioned above the exhaust.
If the VCU is missing then this has no effect on the ABS lamp coming on at start up. Try driving on a soft surface and brake firmly. The car will attempt to skid but the ABS will be heard to rattle as the brakes are prevented from locking up. Be careful though, don't brake too hard otherwise you'll enter an four wheel slide, which the ABS won't be able to spot or correct.
If all this works then it could be simply a case that the bulb has failed in the dash.
If the car just skids on various wheels then look under the drivers seat. There should be a plastic covered bulge on the floor under the seat. This is the traction controller (One of the four microcontroller modules in this model). It manages the ABS, traction control and Hill decent control. This has to be present because you have an HDC status lamp, which is driven by this unit. It could, however be very poorly in which case bring this to the garages attention. This unit makes this car, do not accept it without this working 100%
For you information, when I say traction control this is not the same beast that is found on high performance cars, which throttle back the engine if a wheel slip is detected. On the FL1 the traction control loads up the slippng wheel by applying the brake to that wheel by means of the ABS modulator. This cause the power to shunt over to the non-slipping wheel on that axle. As this can act on any wheel then you have, in effect, the equivellent of electronic central, front & back limited slip differentials. Quite effective too as I have discovered.
With all the abuse us Freelander owners get from the Defender/Disco/Rangy boys & Girls, it is comforting to know that a freelander can not get "Cross axled" like most of the other members of the fleet can. This is where only opposing corner wheels have grip and the other diagonals do not. The standard Defender/Disco/Rangy can not get drive even with the central diff lock engaged.
Before I get flamed by the a-fore-mentoned Boys & Girls, I understand that newer model Defender/Disco/Rangy have borrowed the FL1 technology and now do sport traction control also.
