E39 unable to start-immobiliser / EWS issue i think

[transporter]

hello all,

like to seek some help here..my E39 keys has been giving me some issue for the past months..seeking your help as i am unable to crank/start the engine.

some background :

i have 2 keys, the diamond shaped one. both keys few months ago does not allow me to unlock the car remotely. but the locking and boot release works fine on both keys. hence i was unlocking my car via the key hole.

things i have done that may have caused the issue :

1. i have connect P.A Soft to the OBD module in the car. while performing a full system scan, the application freezes. so i restarted the PC. after that i did not try anything and proceed to point no 2 below.

2. so i thought of solving the unable to remote unlock the car issue and i went online. saw some instructions to put in the car key, switch to position 1, switch back to position 0, remove key, on the key : hold the unlock button, while holding unlock button, press the lock button 3 times.

this way somewhat it will resync the key, i thought this will solve my remote unlocking problem, but it did not. worse still, i tried to start the car engine, but i realise it unable to crank, i am sure it is not the battery issue as all the on screen meters are lit and there is a sound coming from the car whenever i tried to crank (click click and various humming sound). ABS lights are lit too. when i switch back the key to position 0 and try to crank again, it did not allow me to switch to position 2 this time. it just stop at position 1. i will then need to remove the key and reinsert it again to switch to position 2 for cranking (of course this does not work everytime).

3. so after this issue encountered that unable to crank/start the engine. i decided to connect the P.A Soft module to the car and try to see some settings on the EWS section of the software. made a backup on the EWS programming menu and erase the EWS. cleared some error. tried cranking again but no luck.

This problem is due to the GM5 module. One off the relay is worn out. It have nothing to do with the key out of sync since you can unlock your boot and also lock your door. (See me thread on GM5 module)

PA Soft should not hang unless the driver is wrongly. What window operating system are you using?

Good try but this only resync your key but this is not your problem.

click, click during cranking sound like a weak battery or loose battery terminals. check battery connection first.
As for the ignition not turning, try turning the steering a bit

Never use the PA Soft to erase the EWS. Backup is OK. It is not designed to do module coding. There is a menu to see whether the EWS is receiving the code from the key chip. I remember one person have problem starting and it was due to the chip.

Hi Jarance,

thank you for your respond.

1. i am using Win7, PA soft has been running fine all the while until just now. not sure what happen though.

i have just now hooked up a spare battery to charge the car's battery. after few hours, its able to start now. it seems is a battery issue after all. funny. alright then, will continue to search for the solution for GM5 module that you mentioned...

thanks !
