1999 E46 318i car do not want to start. Computer box motherboard is burned where the no 1 plug fits. Can i replace the computer box with a second hand one and is it a question of plug and start or what is...

you can fit a new one from scrapyard but you will need the chip from the key and the transponder to make it work ,a new one in dealers is around a 1000euros and a dealer will not reprogramme a secondhand one for you as they only want to fit a new one (profit) Unless you can find a local auto locksmith who can reprogramme the immobilisor for you but for him to do this you will need the chassis number of the donor vehicle so he can get the 4 figure code to reprogramme the key to the ECU immobilisor .

I can't start my VW 1997 Golf GTI, my battery in my fob is dead

Simple solution ..... chnage the key battery. However, as most keys now hold and retain information which it sends to the main CPU. If the battery is dead in the key, you may have lost that information and are not getting a signal to the CPU. First replace the batteries. Then check through your hand book and locate the section that tells you how to reprogramme the key. There should be a code that you enter and this will be entered when you follow the correct procedure. If problem persists then I'm afraid its a main dealer job to reprogramme key to computer.

Hope that helps

I need a complete igmition system. I lost my car keys and the dealers in my country havent been able to reprogramme the new keys to work with the ECU.

System malfunction. Remote control added or replaced.
Access alarm system control module located under driver's side lower fascia Fig. 2 . Set memory switch to SET position. Press remote control lock or unlock button. Set memory switch to OFF position. Confirm synchronization has been successful by locking and unlocking vehicle. Repeat procedure for second remote control. Synchronization can also be carried out using diagnostic equipment.
NOTE: A maximum of 2 remote controls can be programmed. NOTE: If remote control fails, system can be deactivated as detailed in the owner's handbook. Fig. 2
