Hi Guys help needed please, had the car cleaned today (all doors open for a couple of hours and the battery went flat!!!! had AA out and they have put on the in van diag on it (bosch) ad found everything working apart from the engine management not powering up and the only thing not showing on the dash is the EML. if anyone has come across this before and knows what i have to do or have done it would be a great help.

Russ If i could would you!!!!

When my 2004 car had a flat battery it would not start on jumpleads, we called LR Assistance who told the recovery technician what needed to be done. I wasn't on that part of the call, but I think when the battery gets to a certain (low) level the system immobilises itself, 'thinking' the battery has been disconnected as part of an attempted theft. The solution seemed to involve shorting out the system to re-set it, but I couldn't say exactly what was done. Try calling LRA 0800 521 786, they advised in my case even though I hadn't had LRA since the warranty expired over 4 years before, if no-one else can tell you what to do. Only Range Rovers since 1988

cheers i will try If i could would you!!!!

Sounds like a battery reset.

Have a look in the wiki.  There is nothing that can't be fixed with a hammer😜😜

Did you try the touching battery terminal connectors together (pos lead and neg lead when off the battery) trick to reset the ECUs ? Sounds like the same as "shorting the system"? .

Yes I read the advise, and yes I touched the two leads together and the car is still the same. If i could would you!!!!

An update on this! I left the battery disconnected over night and followed connection procedure and it started but the same has happened today it won't start just keeps turning over!! All the faults coming up ie: suspension inactive hdc dsc all staying on or flashing up in lcd. Just put a fresh battery on and still won't start. Disconnected again and will see what happens in the morning when I reconnect!!! If anyone has had the same issue please let me know.

Sounds like a possibly bad connection to the engine ecu or the battery is just dropping enough to cause an issue FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Just a thought, could it be a dodgy receiver / transmitter for the transceiver chip in the key?

And the other thing is what exactly did you have cleaned? did it include the engine bay? might just be a case of drowned ECU  Yesterday I couldn't spell Engineer... Today I are one!
