  1. Have I blown something in my BeCM?

    Range Rover Mark II / P38
    So today I decided to change the throttle body return hose because there was a crack in the rubber at the throttle body end. In order to dissconnect and remove it from the overflow tank I moved the fuse box out of the way. When doing this I briefly shorted BeCM contact #3 which is underneath the...
  2. P38 Key Fob 2 thinks it is Fob 3, or is it the BECM?

    Range Rover Mark II / P38
    After a series of key fob battery changes and re-syncs, Key Fob 2 no longer works properly. It will only re-sync as spare fob 3 so won't change seat position etc. When Fob 2 is re-sync'd Fob 3 won't work and vice versa. Any ideas how to get Fob 2 working again as Fob 2? :???:

  4. 2000 4.0, Swapped BECM, no keyfob. Unable to lock with key?

    Range Rover Mark II / P38

I have replaced the driver door actuator with a brand new part from LR before the winter, also the fuse...
  5. 1995 DSE; EAS and other faults

    Range Rover Mark II / P38
    Hello all, It's ages since I've been on here. I've had my DSE off the road for about a year after it failed the Warrant of Fitness test (New Zealand) due to leaking manifold. I don't know which one, but I took one good look at all that piping and decided it would be too expensive to sort out...

    Range Rover Mark II / P38
    My last gasp to fix my faulty temp gauge ('02 P38 Thor) is the serial link from the BECM to cluster but I can't seem to find the right plug/wires from the BECM on Rave.

  17. MPG Calculation by BECM

    Range Rover Mark II / P38
    Just read this in an old thread: The On-Board Computer is not very accurate and can only be regarded for guidance. The calculation is carried out by using the fuel tank sender and the total mileage completed since last reset...so if you are on a side slope (even a slight one) the fuel gauge...
