    Please see the WD and trace all the components.

    K line is a communication line and CAN W High and Low are internal bus.

    This car could have more than one K line.

    Driver door open or closed?
    Driver door will not lock if opened (safety feature)
    If it won't lock closed wiring or door latch module.

    good luck

    There is no mention of a radio or RNS-E at addresses 37 & 56 - these use the K2 (or L) line on an 8E chassis.

    So if they are fitted to the car then there is a problem with the K2(L) line.

    I did a few scans but I believe this particular one was with my door open. The car has had an aftermarket stereo since I've owned it. I will try to track down a wiring diagram and trace them back from the door to their source. Thanks guys

    I don't think the RNS-E existed in 2002.

    Only 8Es with a heavy equipment load have a K2 line. Cars with lesser equipment have 56-Radio on K1. I went through all of the cars I could find on my local dealer's lot with a VAG-1552 and VAS-6017 to find one with two K-lines back in the fall of 2001. I'm not sure it's 100% indicative, but the strongest correlation I could find was whether the car had Xenons or not.

    I pulled everything apart under the carpet and checked every wire individually and found nothing. I'm able to get a replacement CCM for $30 from a buddy so I'm going to try swapping it out regardless and see if that gets me anywhere. I noticed I left a few fuses out on my last scan so I replaced the fuses and hooked up the CCM for a complete scan and have more errors than the initial scan. I hooked up a multi-meter to my battery before and after the scan (before 12.53V after 12.16V) yet on my scan it says the battery went down to 9.5V. I should mention when I went to start the car after the scan it was very hesitant. I'm out of my element when it comes to electrical so if the new CCM and digging around doesn't get my anywhere then its going to a shop.

    The DVM readings were taken no-load, with the ignition off, right?

    The voltages VCDS shows for start and end of scan are with under load, ignition on...

    I'm thinking the battery in this car is darn close to shot.

    Would it be odd that the battery went down to 9.5V during the scan yet popped back up to 12.16V after shutting things off without running the car? I would have assumed it would have stayed at 9.5V until i turned it over...but assumptions haven't gotten me anywhere lol and yes, the readings i took on the battery were under no load.

    Odd? No, I wouldn't think it's odd if the battery is on its last legs. How old is it?

    OP

    Before condemning the battery......... trickle charge it.
    Then see if the charging system is properly grounded and that the alternator is putting out what it should back to the battery and that it can cover the function of all accessories.

    Alternator freewheel friction clutches often take a shit ..........in addition to maybe belt slip.

    Readiness: 0000 0100

    I see your LDP and EVAP are not ready here .....have you checked as to why or run these tests?
