Having problems with the immobiliser on a Mk 4 Golf. When I put the ignition key in it doesn't always turn off the immobiliser so you can't start the engine. Under these conditions the immobiliser light is flashing. Same with both keys. I believe it's an immo 2.

Sometimes it takes upwards of 10 tries before it works. Usually at the most inconvenient times. Then it's alright again for weeks. Very annoying.

Found this page

which seems to be the most useful info on the internet on this problem.

I have the key tag with the secret number and a key that will work in the locks. Next time it happens I'd like to try the emergency start procedure in the link above, but not sure which number is the SKC.

There are 2 labels on the key with numbers that might be the SKC.

Is it the 4 digit number behind the scratch off label, or is it the last 4 digits of the 5 digit number that starts with a zero on the other label?

The picture in the FAQ shows it on the left of the scratch off tag. It's the shorter one, not the longer one.

So from that picture the SKC is 00330, and you drop the leading zero when entering the SKC in the emergency start procedure?

Yes. The extra 0 is used when using it with VCDS. Please let us know if the emergency start procedure actually works, I've never actually tried it.

Will do. By the way what is the 4 digit "scratch off security code" used for?

 

[chittychittybangbang]

I have no clue. Can you scratch yours off and see what's under there? Maybe for making a new key? Don't know.

 

[zcx2010]

Scratched it off and it's a 4 digit number. I'd have bet any money THAT was the SKC!

Anyway, next time it plays up I'll give it a try with the 'key code' less the leading zero and post the results back here.

Thanks for your help.
