Sorry to ask but does anyone in East Devon have a T4 or equivalent please? I replaced my battery and now I need resync the engine ecu and the becm.

2004 Range Rove L322 Vogue diesel. Vehicle sat on drive way and no way to move it.

Thank you in advance.

What vehicle?
Just changing a battery shouldn't get you into that state.

2004 Range Rove L322 Vogue. Was running fine and started with aid of jumper cables because battery was dead. Replaced battery and now engine turns over but will not fire. Also key flobs will not work so have to lock/unlock with key. Tried to resync keys by ignition on and 5 sec and all that but no go at all.
 
In struggling to see a link between a VW and a RR o_O
When my p38 loses key sync, sometimes takes ages to resync, suggest patience and perseverance. Do you have a spare fob? Try that one

Sorry where did VW come into it? Oh my I am so thick at times. The T4 Van. lmao. No I was looking for the t$ software to reprogram.
Yes both keys are the same. It has been 48 hours now so I don't think any syncing is going on.
At least nothing else is going wrong with it while it wont start!

You asked if someone has a T4.. to me that's a VW! But I'm written off today, maybe going slightly potty too :)
If it were mine then I'd start again, disconnect the battery.. let it reset and start over. Though I've never worked on an L322, electrics can be funny on any car

Have you been using the key to lock/unlock for a while? Have you checked batteries in the fobs?
Do you get any messages or flashing of the alarm light?

@backinblack may be able to help.

Yes tried batteries in remote and tested that frequency is out put to correct levels etc. All work fine just need a way to re sync the ecu and the becm. Can only be does with a programmer.
 
Have a look at the bmw inpa software it should be able to sort it out, software is free download but you will need a cable there are people doing cable and software for about £70 and it can be use to do most things on an l322 made by bmw as they are basically an X5

He means T4 Testbook LRs diagnostics. Like a super nanocom but pricey.

I’d check fuses and things, L322 dont like being jumped is not wise. Take battery off if possible and charge it. If it won’t hold charge it’s stuffed anyway. Jumping can cause all sorts of expensive electrical nightmares
 
I've jumped mine a few times and disconnected the battery many more but have never had a problem.
As above is the new battery fully charged?
What size battery did you fit? Most recommend the MF31-1000.
Does it start with easy start? I've had a failed fuel pump cause a no start.

Never heard of the need to resync the engine on the L322, it doesn't have a BECM like the P38 it has a BCU.

The new batt has cca 95. The fuel pump was replaced last year. That's the one under the rear seats and the one under the vehicle on the left hand side as well (Which most people don't know exists).
