VW Golf Immobilizer diode replacement

My car broke down suddenly, firstly electrics went and minute later the engine cut out. I was told it was the alternator. This was replaced but the car still wouldn't start. This is seemingly due to short-circuiting of the red light diode of the immobilizer on my dashboard, replacement of which is pricey and time consuming...is this true?? I was told this was because in VW the dashboard dials are in one unit, so the full unit has to be replaced instead of just the small bulb.

The immobilizer isn't recognizing your key. You need to reprogram your keys to your car. Unless you know the SKC and know someone with VAG-COM you are going to have to go to the dealer.

Did you try all the different keys you have for the car? If you are lucky only one key is bad and you can drive to the dealer and get the bad key reprogrammed or buy a new key and have them program it to you car. Otherwise, you are going to have to get towed.

If it is just one key, make sure you bring all the keys to the dealer so they can do the reprogramming correctly.

Was any work being done on your car to cause this?

try your spare key first,if that doesnt work you will need a dealer to recode it unless you have the skc code for it then anybody with vag equipment will be able to do it for you

most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.

If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.
Good luck..i hope this helps...please take a minute to rate me a fixya.

SOURCE: electrical problems in 2001 Mitsubishi Eclipse

Hi,

I had the same problem. It seems that multi purpose fuse (#13, 10A) blown out. And this fuse its part of the charging diagram system and also from meter gauges system. So I discovered that the speed sensor harness was the problem.

Try to look for it and replace it ( its under the big air filter hose).

Good luck

Does a 1.4 16 v vw golf have a maf


this is a later model and not a 1999 and as such it may need the engine diagnostics reading as such this vehicle has to be connected to the internet via dealers digital signature to source the problem ,even if you know what part you need and change it then it still needs programming in to the car computer this is out of the realms of a weekend mechanic and for that matter even a mechanic like myself ,so you will gin and bear it and pay the dealer and get used to this as the newer the car then the less can be done to it by anyone except the dealership.

Vw golf cutting out


No it is impossible to say without testing the vehicle and doing a complete analysis with the correct diagnostic equipment.

These vehicle have numerous electrical faults that sometimes the VW dealer service centres cannot diagnose. What has been happening to you is the mechanics have been guessing what the problem is and just changing things without really identifying the actual cause - as you have now found. These are very unreliable cars so do not be fooled by the "german quality" label that people frequently and wrongly apply to German cars.

If you want and need a reliable car I would recommend you get rid of this Golf and get yourself a Mazda (and have any prospective used car thoroughly inspected before biuying). If you keep the Golf I guarantee it will give you much grief and cost you plenty more repairs.

Vw golf stalls at lights and roundabouts


Check out the rubber/metal flange that joins the carburettor to its manifold. Wait while the engine is cold. Then check if the carburettor moves . Do this by taking hold of the carburettor and moving it a little side to side. The rubber mounts are known to perish after a time and this can cause air to be sucked in through the cracked flange rubber and in turn causing the engine to drop revs. The flanges are a replacement part and not too expensive so its a relativley easy fix if this is the problem.
GOOD LUCK
