Thought I would "relay" some problems with the RF receiver experienced on my P38. On cold mornings the engine (DSE) would race for the first few minutes, auto gearbox would lock in 3rd only and suspension would drop onto bumpstops. Every message that the BeCM could think of would come up. On normal mornings the battery was frequently flat. It was only when we went away for a few days that I realised it was back to normal.
The cause was that I park my vehicle outside my office on the end of our house. The RF receiver was picking up signals from my wireless modem and automatic weather station (433 Mhz) causing the BeCM to wake up constantly which drained the battery.
Although expensive at £126 plus VAT, I replaced the old one with the updated unit part no. YWY500170 and everything is back to normal including remote locking. The best way to test for rf receiver problems is to disconnect it under the rear r/h parcel shelf and use the key in the door lock. (only takes five minutes)
I hope that this is of use to others who may be experiencing similar problems. Information is available on Battery Drain on a Range Rover 4.0/4.6
