Do a search on Ebay, leads and software are available to obtain the SKC (about £20 with delivery).

With the right equipment, you can lift it from the
instrument cluster-immobilizer. But you might
need VAG-COM to get it to go back in again.

Try a vag specialist or tuning shop, near you,
for a call-out service.

thanks jim

but i have the coding from my ecu (which is broken) and cluster etc i just dont have the code from the new ecu i have heard something about vagtacho but vagcom does not work my mechanic tryed it on his

i'd do pretty much anything if someone could get the code from my second hand ecu lol

You can get the code with VAGCommander software and cable (not the same as vag-com/VCDS) and I think you can with VAG-Tacho software too. "reading security access code of immobilizer"

You can get it from ebay.....

I'm confused. If you haven't changed the cluster, why would you need an skc. The immobiliser is in the cluster so your keys are still coded to that cluster. The engine ecu just needs the same coding that the original engine ecu had. You can do that with VCDS. It's only got a few settings like transmission, country etc.

Thanks Snapdragon will go and have a look now Thanks

Thanks Martin1810 thats what i thought but when i pluged in the new ecu the key light flashed and my mechanic tryed the coding he said i need a pin from the new ecu i have got my ecu coding number, service code, pin number from my oe ecu but need these numbers from the new one im a bit confused i know a bit about cars but this baffles me lol

Did you select the correct immo?

**martin1810** · 11-11-2010,09:52 PM

When you try to start the car, what happens and what fault code do you get. Are you sure it is not the cluster that is faulty. Did you save the coding from the old engine ecu before you removed it. If not, it should be possible to work it out as long as you have the engine code. I can't see why you need numbers from the new engine ecu as it will still be set for the previous car.
