    2010 Audi S4 B8- Alarm Keeps Going Off

    Afternoon All,

    I have an issue with my alarm, which goes off randomly, usually at night. I'm hoping someone has had a similar problem.

    Car: 2010MY B8 S4 Avant (without keyless entry)

    Problem: Alarm goes off randomly at night (3 times last night, hasn't done it for 6 weeks or so prior to this)

    Containment: Unlock car with fob, lock again.

    Info: All door locks work fine, no other issues with car. (data logs below)

    My question is what is the root cause of the alarm going off, at the moment I have two thoughts:

    - Door handle sensors (known fault)
    - Vehicle energy management system (thinks 12v Battery is low, possibly reset current battery adaptions)

    So, first a log from this morning:

    Code:

    I then did some further digging on VAG-COM, and interrogated the convenience module:








    After some digging on the internet I found the following, a TSB for A5/S5/A4/S4 regarding a similar issue- not my car does not have keyless entry.




    The symptoms are all very similar, but my information isn't sufficient to know what the codes are in Module 46 > Block 18 (i.e. what does a value of 2.0 mean?)


    - TSB suggests Value 2 (no communication)

    - VW 'Tech-Tips' suggests Value 2 (Front Passenger Rotary Latch Switch)




    So, where to go from here...?


    My other question is regarding handed faults (i.e. passenger side) is Ross-Tech mature enough to understand implications RHD/LHD regarding fault handling. I.e. I'm using a VW America Tech Tip to decipher a European fault code, I presume fault code descriptions change with RHD/LHD?


    Further information on supported codes my car has:


    Module 05: Nothing Stored

    Front Drivers Door: Nothing Stored

    Front Passenger Door: Nothing Stored

    Central Conv:


    CAN 19:


    Rear Left Door:


    Rear Right Door:




    Any help greatly appreciated!


    Many Thanks,


    Pete

    Please wrap those scans in [Code] as explained here: How to post an Auto-Scan

    We do not have all of the alarm sources for BCM2 documented so please run a control module map as explained in in this similar case so we can evaluate all of the applicable MVBs.

    You can either open that map with Notepad and wrap it in [code] to paste it here or email it to us and I'll paste the relevant information in this thread after we evaluate it.

    What's with the list of alarm sources for Touareg/Phaeton? I wouldn't count on those to apply to a B8 A4.

    My other question is regarding handed faults (i.e. passenger side) is Ross-Tech mature enough to understand implications RHD/LHD regarding fault handling.
    We've only been doing this for 14 years now. But as for how mature we are, well..

    Generally, VW/Audi has used Driver and Passenger sides to designate things in the front (instead of Left and Right) for precisely this reason -- there's asymmetry in the way the stuff in the front row is designed. Since there are typically no such issues in he rear, they use Left and Right. Anyway, I think it's a safe assumption that Driver and Passenger sides mean what they say regardless whether the car is designed to be driven on the right or the wrong side of the road.

    Will do- apologies about the code!

    Uwe, for sure I shouldn't assume they're the same, I couldn't find any other reference (aside from the Audi TSB attached above) ref module 46 block 18...

    Thanks for the info on the handing too

    Jack- is that based on previous experience, or a best guess?

    I've never known Jack to guess... he uses empirical data and experience.

    And he looked at this:
    Code:
    1 Fault Found:
    
    03041 - Energy Management Active
    
    000 - - - Intermittent
    
    Freeze Frame:
    
    Fault Status: 00100000
    
    Fault Priority: 7
    
    Fault Frequency: 11
    
    Reset counter: 57
    
    Mileage: 122598 km
    
    Time Indication: 0
    
    Date: 2014.07.30
    
    Time: 05:50:00
    
    
    Freeze Frame:
    
    Bin. Bits: 00000
    
    Voltage: 12.30 V
    
    Count: 17
    And the vehicle is 5ish years old - almost exactly when all Audis need a new battery in my experience
