    Radio causing battery drain? 00858

    Only weird thing I can find is that the left and right rear windows measuring block content are different? Windows are operated by crank if that helps..... Any ideas?

    Radio causing battery drain? 00858

    Another quick update, unplugged the motion sensor in the light above driver and hazard goes off. Are there any fuses or relays that this sensor or the interior monitoring/immobiliser etc. are connected through I can check as there are none in the dash on the left of the driver. Any under the...

    Radio causing battery drain? 00858

    Another update: Definitely interior monitoring by the looks of it, went outside started car, turned off, hazard on when locking. VCDS plugged in, read codes, no codes, measuring blocks, 01 = 001, lock car and it quickly changes to 000 then back to 001. Turned off Vagcom, locked, LED blinks for a...

    Radio causing battery drain? 00858

    Yeah its become a real pig of a job. Relays can be tested on a 12v source and meter, but usually when they go you can hear them clicking away. Interesting thing I noticed is when you watch the door leds they do a red flick every second or so for about 30 seconds then they slow down, at the exact...

    Radio causing battery drain? 00858

    Update, think its got something to do with interior monitoring, when I VCDS I get no codes in interior monitoring or central convenience, I go into measuring blocks in interior monitoring, 01 = 001. Then I turn off ignition while still in measuring blocks, remote lock car 01 quickly shows 000...

    Radio causing battery drain? 00858

    Spoke to an auto elec, he said theres probably a split in wiring looms in the doors or one of the door modules is gone, or one of the locks or the CCM is knackered. He says the CAN system doesnt allow the CCM to power down completely until 20 mins has passed, after that if the system doesnt...

    Radio causing battery drain? 00858

    Right, pulled fuse 24 and can confirm it turns the hazard off. Only info I have on systems this controls is as follows. #24 - Central Convenience Electrical System - Map, Glovebox, Vanity, Trunk and Overhead Lights. Anybody know if there is anything else it does? Thanks

    Radio causing battery drain? 00858

    From what Ive read elsewhere, Audi hazard lights stay on when theres a electrical fault/short/charging problem. Id like to eliminate the cheaper options first and leave CCM till last if possible.

    Radio causing battery drain? 00858

    Carpets are bone dry, the chamber its in is bone dry, the unit itself doesnt look like its seen water and neither does the wiring. VCDS isnt throwing up codes and everything works as it should besides the Hazard light staying on. From all the cases Ive read of CCM failure there are more...

    Radio causing battery drain? 00858

    Bit more info, a couple weeks back I pulled fuse 24 (convenience module), hazard went off immediately but Im convinced its not the CCM but rather something in the "loop" like the alarm siren or similar. I will try pull it again and see what it does.

    Radio causing battery drain? 00858

    Does anyone know what the relays under the driver side dash and the fuses under the ECU in the engine bay do? Just wondering if one of these isnt gone and causing a short?

    Radio causing battery drain? 00858

    Yeah it does go off like that when triggered, quick flash of indies and the alarm triggers. Thanks for the heads up re glue gun. Just wondering if its the alarm why Im not getting any codes? I have read of TT owners instrument panel not shutting down properly and causing drain, fixing by wiring...

    Radio causing battery drain? 00858

    If I park it Friday evening, by Monday morning it would be dead. Just a click at ignition, central locking wont work etc. Thanks Ill try that, would the trim need any special clips like the door cards in case I break any? Is there anything I can do to make sure the alarm is functioning as it...

    Radio causing battery drain? 00858

    Thanks Andy, do you know how I can disconnect the alarm? Can you PM me if youd rather not post the info. Basically, I drive home from work, get home, reset hazard, hazard off overnight, hazard still off next morning, unlock car, hazard on, lock car to test, hazard stays on permanently till I...

    Radio causing battery drain? 00858

    Yeah, when I pull fuses, air con and instruments cause it to drop when car unlocked but thats probably because they arent shutting down due to car being open. When I take a reading and lock the car the drain drops from 0.9 amps to 0.09 amps with hazard on. When I reset using vagcom the hazard...

    Radio causing battery drain? 00858

    Hmmm, thanks Andy, took radio fuse out and drove home, hazard light on again, did a scan and this time got a code Ive never got, 01134 - Alarm Horn (H12) 29-00 - Short to Ground, cleared and hazard went out. Only thing I can think of now is that theres a damaged wire thats throwing up these...

    Hi Guys, 8E B6 A4 Concert 2. Some of you have been helping out with my parasitic drain issue in the B6 forum(thanks), flagged up some CCM codes and some door lock codes, I found some sheared wires in the door, last place I checked! (AAARRGGHHHH!!), fixed them so no more weird codes when...
