Hi Mathew-

Thanks for the note.

I specifically asked the technician about the ground wires. He told me that the wires were a common problem and that they had checked out just fine on my car.

I would not trust a dealer mechanic with a bicycle. Those guys are almost always out to rip you off because you have no alternative much of the time. Sounds to me like they did not fix anything. If I HAD to use a dealer, I would certainly pay with a credit card that would allow disputes, and not hesitate to threaten the dealer. Three BECMs? Thats just rediculous when combined with the fusebox and some relays?

Still sounds like bad grounding to me.

Thanks for the note Dave-

Given your opinion on the grounding issue, can you give me some thoughts on what/where to check?

Thanks Dave

A pain in the arse to check out but a faulty door lock mechanism will also lock/unlock the doors and cause the dome light to illuminate.The battery will run down as the BECM is being woke up and the lock itself if its being powered up all the time.Just read back through your post,the alarm ignition tamper is probably due to you trying to start up on a flat battery. Check out the drivers door locking mechanism first,if unsure disconect for a while and live without central locking.Had this fault on another model pulled my hair out for months looking befor i found it for it

Hi Shiftech-

Thanks for the note. How might I check these?

I hooked up a meter last night and I am getting .85 amps off the battery.

Thank you!

Hi Scott,
Jes that was quick lol,look for any signs of heat/burning operate the it a few times ,shake it ,hit it swear at it.seriously operate a few times making sure the other doors lock /unlock.Tap it with a screw driver handle when open and shut to see if you get any reaction off the other locks or dome light.if nothing then just disconnect it and see if the fault recurs over a few days or so.I was lucky the motor housing was charred brown so I didnt have to dig to deep.At work at the mo will have a look when I get home .

Thank Shiftech- I'll give it a shot!

Off the top of my head the BECM should draw about 0.06A when in stand by,Hook up your test gear and leave for about 5 mins to see if BECM goes into sleep mode,On UK spec vehicles doors will auto lock if unlocked but no entry is sensed I.E door opening .Dome light iluminates when lock is opened ,extuingishes when lock closed.

Well how did you get off Scott?

Hi Shiftech-

Local LR dealer (165 miles away) brought me a loaner and picked up my car a week ago. The technician called this morning to state that they have been unable to duplicate my problems. The technician suggested that a replace the battery (possible internal short) and replace the driver's door lock mechanism (to address the self door locking and dome light problems). Hopefully they will shuttle my car down within the next couple of days.

Do these repairs make any sense to anyone? I'll now be out some $4000 total on repairs! At least the dealership has sent a technician down one time and supplied me with a vehicle ('02 Disco) and picked up my car another time.

Does anyone think the entire epsiode could have been related to a bad battery??

Hi scott,
Why the hell don't they just test the battery with a high rate discharge tester?
I bet they are only sending someone because they have rubber ducked big time,and are waiting for you to ask for cash back on the BECM.They changed the BECM to no avail and are totally lost.The problem with LR technicians is they have all the kit to test everything on the truck but lack the know how.I am dubious about it being the battery,but the more thought I give it the more it points to a locking mech problem.
I had a ABS fault up on every start up,after changing everything to do with the ABS it turned out to be the battery,After a lot of arguing and threatened court action I only paid for the battery.REMEMBER they are the experts( )and therefor should diagnos and not substitute parts untill the fault is found.Hope you have some luck this time

Thanks man, we'll see. The car gets back home tomorrow.
