Engine immobiliser fault light on after battery flat

SOURCE: Immobiliser problem - 94' Golf Mk3 GTI 2lt 8 valve

just unplug the immobiliser unit. its behind the glove compartment for rhd models.

Interesting problem.. since not US spec. Is there a 'remote keyless (fob)' programmed for this vehicle? That's the only way to DE-arm the immobilizer (anti-theft) feature (based on US specs). Unless you have this key fob (keyless entry remote... which must also be programmed for this vehicle), the only other way is wait 5 minutes with the existing key in the ignition, then it should start (US specs). You will still need to have an 'ACTIVE' keyless remote programmed for this vehicle... otherwise, you'll continue to run into this problem.

SOURCE: Engine won't start. Dash lights flash rapidly when key turned.

the battery says 12 volts but may be dropping to 4 or 5 under a load...i would suggest jumpstarting the car and see what happens.the battery should read in the high 12 volts and not less than 9.5 under cranking. the dash lights go out on your car when starting,and the alarm will go off ,and disable the ignition if the voltage is too low in cranking the car because the computer will shut it down and activate the anti theft.....check your battery posts are tight. best of luck

1-insert and remove key from ignition two times

3-insert and remove key once from ign.

4-close and open drvr door twice

5-insert key into ign.,then close driver door

6-turn key to on (not start) then off, twice this is rewrite mode,have all remotes to reprogram it will clear any lost remotes.

7-remove key from ignition,the door locks should cycle twice.if not start over.it may take a few tries.

8-press lock/unlock together and hold for a second

9-release,and press lock on remote,the door locks will cycle confirming program.continue to do other remotes you have,steps 8 and 9.if only one in possession,you are done. To end mode open door or insert key into ignition.

You'll need to follow the steps with no more than a 1-2 second delay between each step.. hope it works

you cant if it has the emobilizer on you would have to know the resister number to install a resister chances are its already gone. there be a reprogram you can do to get it going sometimes when the battery goes dead the bcm will lose some of its programing . hope this helps Tunderboltz.
