Chip tuning can remove it entirely. There is no easy way to bypass it like jumping a wire because otherwise it wouldn't be a very good anti theft tool would it?

If you have problems, why not post the error codes and what troubleshooting has been done so they can try to fix it?

So I tried the emergency bypass start with no luck. The car cranks but doesn't start. The fuel pump doesn't kick on and there is no spark. :(
You don't have an immobilizer problem. The immobilizer still lets the engine start normally, it just shuts the engine off after a second or two. Have you checked the fuel pump? Your profile doesn't say TDI so I'm assuming it's a gasoline engine. If the fuel pump doesn't kick on it could have died. If there's no spark and no fuel pump, check your ignition switch or maybe the alarm relay?

Thanks for chiming in. I have a 1.8T gasoline engine. The fuel pump relay clicks on/off when I cycle the ignition switch. Another clue, the tach will go to 200 RPM when I am cranking the engine.

Alarm relay you say...More researching.

I have a problem with my immobilizer (Golf IV '99), the key is faulty and a new one is gonna cost me €150 (that includes reprogramming). The key I can manage but the thowing is gonna cost my another €300 I can't afford right now. Is there a way to bypass it?


EDIT
Nevermind, found the immobilizer section, sorry for kicking this thread.

Thanks for the help. I had to go to justanwer.com for a VW expert (I was stumped). After a few of hours of electrical troubleshooting, I found two ground wires under the battery tray that were corroded. Thanks VW - nothing like putting hidden grounds under a battery tray of a lead acid battery. :bangshead

Thanks for the tip, I am starting a can't start article. That is a tricky one. But as you found out, if it doesn't start it's not the immobilizer.
