I have a 2000 volkswagen jetta with immobilizer problems and will not start and will leave me stranded. Is there any way to disable this without having to cut wires? Any input appreciated.

You can use the SKC number to use an emergency bypass mode. If you don't know the SKC number you're out of luck. Use the tips in the immobilizer troubleshooting article.

Cutting wires won't help. It's fully tied into the ECU and the car won't run without it.

If its IMMO2, there may be a way to do an emergency start if you have the SKC. IMMO3, youre outta luck. Im having my ecu done to take the IMMO out; ive had way to many problems with it.

This propblem is often caused by a defective reader coil in the ignition switch. When the transponder reader coil is bad, the transponder signal from the key fob is weak or non existant, so the immo locks out the ECU. If confirmed the problem, the ignition switch with transponder chip reader coil must be replaced.

I have the immobilizer lights on. Car start and shut off in 2 sec. Tried left the key in on position with charger to battery for couple of hours, also touching both positive and negative wire but none of them work. Get locksmith come and re-program the key or even trying to by pass the immobilizer. However locksmith can't make it as they claim something to do with the "ignition ring". So I'm down to either ignition cylinder with immobilizer antenna or the ignition switch problem.

I can start the car with emergency start up (use trip reset and clock knob to enter the PIN code manually). Wondering if the ignition switch still be the root cause where I can't start the car normally?

Hi buddy, cutting the wire won't help. Better try offline and do update the thread once you get the issue solved
First posts normally go in introductions else you could get a free fix and we never see you again!!!

Forum Rules and Guidelines

This is a new forum layout with loads of bugs which have been reported in the new thread. There is no TDI Wiki at the moment or or original similes. It doesn't show the car spec/location or signature properly either

We Are Live - Community Feedback

This has been talked about many times.


I've made a pole which no one has posted in.

Do you like the new forum features?

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.
