Question about 1999 Volkswagen Passat

VW Passat failing to start/security alarm issues are they linked?

Hi, recently I have been having an issue with my 99 Passat sometimes failing to start, (I get all my dash lights but it won’t turn over, the battery has been tested) that being said I have also been having issues with my security system led flashing constantly since last summer. (I already checked fuses and replaced the relay but it still keeps clicking and flashing constantly) Could these two issues be linked, in other words does the Passats' security system cut ignition if it thinks its been broken into. Let me just add this all started with electrical problems, I had to disconnect the automatic lock for the truck because it kept constantly engaging the lock and running my battery dead. Any advice you can give me on these trying issues would be greatly appreciated.

    same kind problem, took it to dealership and they dont seem to be able to find problem. replaced module under carpet and no help. told me they need to take all 4 doors apart to text each module and dash. why cant they test each through scan tool? is there something that i can to to see where problem is?

Usually on the passat, if the immobiliser is on, there is a yellow key symbol flashing on the clocks as you try and start it. Do the doors unlock with the remote key? If no flashing light and the key fob working, i would be looking at possibly starter relay. This is either located under the fuse box or under a plastic cover near the windscreen under the bonnet.

Disable 2003 passat alarm


check the door jamb sensors and the hood and trunk open sensors one could be bad causing thr security system to engage are all of the doors locking when you press the lock does it say trunk ajar? ckeck under the hood as well because if the car thinks the hood is open the security may trigger also because thieves can pop the hood anddisconect the battery so some cars have a hood pop sensor they should look like a little.black button somewhere near the front

2003 VW Passat wagon, trunk alarm keeps indicating the luggage compartment is open and alarm goes off. Many dealer attempts to fix have failed. Is there a specific fuse for the trunk latch/alarm?


Hi

You have to replace the latch of your trunk. The contact is in the latch and most of the time you have to change the wire and the connector because they are oxided and make a resistance.

If I remember well you cannot remove any fuse to solve your problem because the fuse will affect some interior lamps and door lock system.

99 Vw passat, changed cracked oil pan now engine statrs up and shuts down after a few seconds as if a security issue


The oil pan should have a sensor in it that is just for that reason. If it looses so much oil it will shut the engine down to prevent engine damage. Either the sensor is cracked or broken or the wires going to it are not plugged in or are broken.
