Alarm And Interior Light Issue?

[Reborn996]

Okay, noticed my interior lights and trunk lights were not coming on with the doors and hood opening. The lights do work on the inside once the key is in the ignition so I know the bulbs and fuses are okay. I just replaced the drivers side door lock due to a bad microswitch...checked the car with Durametric and found two codes under Alarm for DTC 33 and DTC 60. Would these cause the lights to not function right? No other issues and the alarm seems to work okay with no horn beeps when arming it. Durametric can't clear these codes so not sure if I have to get them cleared by my local dealer to get my interior lights to work again. Anyone else run into this?

Thanks for posting. I have the same problem and am looking for a solution. The trunk and bonnet and interior lights come on when the door is open and the key is on but no lights anywhere before the key is turned. I haven't checked the alarm yet. I hope someone posts a solution here soon or off to the dealership I go with checkbook in hand.

You need to get your alarm fault code(s) read.

Thanks for the interior lighting/alarm advice Loren. I'll post my updates soon.

By the way, I used another one of your posts this weekend to replace the Tiptronic shifter button. It was an easy upgrade, thanks for posting the pictures and instructions. I would have never figured out how to remove the old button without those pictures.

most likely a blown alarm module (15AMP) fuse under the driver seat,,,
