If your BCU ends up being the culprit then you may want to consider a professionally reprogrammed BCU unit that is programmed in advance and shipped to your door, ready for installation. Based out of the UK. Call them or fill out the contact form. Cheaper than new unit but better than using an old used unit.

The Speedometer is flashing because the mileage does not match with the mileage from the ECU/BCU.
When you swap the ECU/BCU the Rover is immobilized.
You need to use the EKA, or turn the key in the ignition to the 2nd position and leave it for 5 minutes to sync.

I would look into the motor as the culprit. It seems more likely the window motor went out than the BCU.

 

Thanks for that info, Nick. Is it common for both motors to fail at the same time? Exactly the same time?? Both windows worked fine a few time earlier in the drive. The last time I sent them up, the passenger side went all the way up, the drivers stopped prematurely. Now, neither side will do a thing. Not saying it doesn't happen, just seemed a bit odd.

As a side note, per TRIAR11's suggestion, I talked to Turner Engineering this morning. Nice fella, very helpful too. If I do determine I have a bad BCU, I may send both to have them repaired. No harm in having a spare.

 

If it's not the BCU, I have a good front passenger window motor. Free if you or anyone else needs it.
Window in my 04 would jam. As suspected, the track had a broken wheel/bushing. I had bought a motor too, just in case, but the motor was ok.

 

Cool Offer, Six!! Way to pay if forward!

 

Thank you sir.
I have a few things if anyone needs them.
I need to start a new thread.

 

I missed that it was both windows, I thought it was just the one.
Sync the new ECU/BCU by leaving the key in the 2nd position for 5 minutes and see if that changes anything.

 

I just wanted to clarify that "Turner Engineering" and "Turner Diagnostics" are 2 separate companies, both based in the UK. Turner Engineering specializes in professionally remanufactured land Rover engines and cylinder heads while Turner Diagnostics appears to be a specialized repair shop with specialization on electrical and remanufactured BCU's for our Rovers.

Cheers and good luck.

PS: Im going through same **** with my front windows too. Except my front driver motor and regulator are new, all the fuses and the relay are good. I feel your pain

 

Tried swapping out the new/used BCU this morning and went thru the minimum 5 minute wait before trying to start the truck.

Nothing changed with the windows and the truck will start and then shut down.

Looks like my next step is to get one or both of my BCU reprogrammed in the U.K. Or...... can a dealership do this. I believe the closest to me is in Atlanta, about 2 hrs north

LandRover of Buckhead

Any Georgia members have any experience with this dealer ?

 

Dealer can do it, but for the price might be better to buy a tool that can do it, or a matched set of ECU, BECM, and guage cluster.
