Thanks for letting me know, did you have any scanned error codes ? Which pointed to the BCU and did you buy second replacement ? And have to have it coded to car?

What Dolphinboy said and it was intermittent on mine so some days the steering had gone and other days the steering was fine. Test it by moving the passenger seat forward and unplugging the BCU to drain the power then reply it back in. I bought a new unit and flashed it myself (Faultmate) having downloaded the coding from the old one.

Yes, it would work on and off but only needed to be unplugged briefly. There’s three plugs so unplug each one and by the time you’ve unplugged the last one, plug them back in and the steering may work again. Not saying it will, as that depends on the issue with the BCU, but the chances are it will reset the unit. You could also switch the engine off and restart if the PS isn’t working but if it is always inoperative then the restart may not work.

Question does anyone know if a second hand BCU contains mileage data? If I bought a second hand one would it adjust my mileage ? Don’t want a secondhand BCU with 200k and this affect my mileage on the car. 2003 Range Rover 4.4 Litre V8 - Adriatic blue

Managed to get a second hand BCU good price, from same model as mine with same features regarding auto locking doors so on, from reading online it should just work and re link keys.

No it doesn't change anything and shouldn't need re-programming. Simple swap but be aware that there are 3 part numbers: The original and then 2 updates. They all work so best to get the latest one (mine was RANGE ROVER L322 VOGUE 2006 4.4 V8 BODY ENGINE CONTROL MODULE ECU YWC000922 - the earlier ones were 0921 and 0920 IIRC)

Only thing I have lose is when I hit 10mph it use to auto lock which I liked. New BCU don’t do this but much rather have power steering again.
