How do I disable or bypass the immobilizer in a 01 Beetle? It shuts down the car after a second so any help would be appreciated.

Well Sir I tried to post to the forum as you requested. I just couldn't find the active link to do it. I apologize, I guess after a day of running my repair buis. I am just a bit cross-eyed. I might try again tomorrow. Thanks.

You registered today for the first time, how could I have banned you before? My previous comment was directed at someone else. Seatman included the link, just read the links to the FAQ articles, most of these are common questions that have already been answered.

Hi! A friend of mine has a 2001 Golf. Previously he had a problem with driver side door - it always had a light on the dash saying that it is open. He went to a garage and they disabled something and the light came off. Then a week ago the battery went flat. We recharge it but now the immobilizer is not accepting two originally fitted keys. I have the key reprogramming equipment SBB which you connect to the OBDII connection and then you program the ECU to accept keys. But it is asking for a pin. That car he had bought 2 years ago and he never knew the code. Is it possible to find the code or bypass it? Could you help me please? :confused:

First the light on dash saying the door is open is probably a faulty door module. It's very common. A microswitch inside the door module goes bad. Either that or the wire harness is cracked in the door hinge area.

The SKC code should be on the black key tag. If he doesn't have it, take a look at the immobilizer FAQ on how to get it.

Thank you. I may not smart enough but it does not saying how to bypass it and how to get the pin code. It is reffer to FAQ 4.15 but I could not find that charter.

you have nothing to lose, according to el. diagram I see that behind the gauge cluster is green connector, find pins 2 and 17 this wires are related to immobilizer one will be green and one will be black wire, so try cutting one of them before engine dies. If nothing happens, then try starting with one of them cut.

I don't think that vw would make it so easy to bypass, but you never know. You can always at the end connect wires back to normal. Also if this works, then you could extend wires and install inline switch to disconnect circuit etc.


Also it would be helpful to know what immobilizer disconnects, I believe that the only way to shut down diesel engine is by blocking fuel delivery. If that is true then we would have to find diagram for fuel pump and injectors and see how to bypass power to them to keep them running even if immobilizer tries to disconnect them. Maybe you can connect voltage tester to certain pin on the pump that is supposed to have voltage with engine running and see if that pin loses voltage when engine dies. If we determine what component loses power or ground when engine dies it is easy to bypass it with a relay or two.

Maybe it cuts voltage to ECM and then everything dies with it (pump, injectors etc) you will need a good el. diagram with power and ground distributions to fuel pump, fuel pump relay, injectors, and ECM. Then you will know exactly what pins have battery voltage when engine is running so you can have someone hold the voltage meter at each of the mentioned components to see which one loses voltage when engine dies.

Hello guys, I've just got here via Google. My car started but stopped after few seconds. I have unplugged battery reconnected it. Now it's working. Don't know why. Hope it help someone with same problem.

Still, I want to know how could that happened and how to prevent it from happening again.

Nice knowing this forum. :)

Heellllpppp!!!

I also need help with immobilizer. I have 2000 Beetle and would really like to disable the system either temporarily or permanently. I have good electrical experience and work on vehicles for a living. This is my youngest daughters car and live a significant distance from the VW dealer. Please help if you can. I too am having difficulty navigating the forum. Thanks for any help in advance as it is greatly appreciated.

If you have the SKC number you can input an emergency bypass, see here http://www.myturbodiesel.com/1000q/multi/immo-2-vw-audi.htm Without the SKC you can't do squat with the immobilizer, it's built into the instrument cluster and ecu programming. Only way to remove system is ECU flash, check out kermatdi.com and malonetuning.

i bought a 60$ obd2 immo drive box from ebay, it worked to disable the immo, the lights flash on the dash but a 2ct piece of black tape took care of those, sure beats 200$ for a key or a "chip tune"

interesting...

I got an uncut key, so If I buy that, can I make it work then?
I'll take a look...

We are having immobiizer problems as well. We have always only had the one key. We had some work done on the car last week and also had to replace the battery. I read if the battery gets low or has to be replaced it couldl trigger the immobilizer. My husband drove it to work the other day no problems but couldn't get home after work as the car wouldn't start. The "car" is flashing on the dash and the read out states "Immob. Active"

Don't understand all this and hope someone has an easy answer for us.
