hi there,

i change my battery on the key when it showed low battery and now, i cant use my convenience key to unlock at the door sensor nor can i start the car.

it was working fine before.

i thought it might be the antenna in the center console so i changed that but no joy.

heres my scan.

thanks for having a look.

Fundamentals first. Have you got the battery orientated as mine?
Does the LED give a strong red when the battery is pushed back in?
Does the LED flash when you press a button?
Does the car unlock when you press the unlock?
Does the LED flash when you put your hand around the door handle?
Does the LED flash when you press the Engine START/STOP button?
Do you hear the very feignt 'tweep-tweep-tweep' when you push to start?

Was that fault in 05-Acc/Start Auth caused by you disconnecting the antenna; or was it there before?

Do you still have this fault?

Code:
00183 - Interior Access/Start Authorization Antenna 1 (R138) 
            007 - Short to Ground

Hi, thanks for having a look.

first to answer Zeners questions.

Battery orientation is correct.

led lights up when pushed in.

led flashes strongly when pressed.

car unlocks and boot opens when buttons are pressed.

led does NOT flash when touching the handle, nor does it flash when start/stop button is pressed.

I've never heard the faint tweep ever before.

And as to the fault, I only did a scan after the key stopped working. and yes it is still there even after the antenna change.

clearing it doesn't help as, after i press the start button, it comes back.

and to add further, the start button works if the key is inserted into the ignition. once inserted, i can start and stop the engine.

The reason the key runs in ignition is it sees the key coil antenna.

The R138 antenna is in the center console.

Attempt recoding and defaulting the module and readapting the antenna ....or after the short to ground is corrected.

Verify in WD on page 23

Check wires T32/e 16 & T32/e 15 to pins 1 and 2 of the antenna.

Verify all fuses for CCM J393

Thanks for looking jack.

So is the r138 on the right door if my car is a rhd? I looked in the service manual and it shows r138 to be in the centre.

And I'm sorry but after that your post gets confusing. So its the j393 unit in the boot is it not? I don't really have or know what WD is.

Ah you meant wiring diagram. I'll have a look

I just had a look at the WD. There are only 2 antennas on the j393. One in the centre console and one in the boot. Is that correct or am I confusing it with something else. I'll try and post a screen capture.

marc: is this the aerial that you replaced?



Could it be that in trying to solve your key problem, an inadvertent second issue has arisen (i.e. the shorted Aerial). Sounds like you have taken Jack's sage advice with the WD. Can you check the two wires (perhaps remove the 2 wires from pins 15 & 16 on J393 and using a high impedance multimeter measure their resistance to the car body)? The WD indicates that both these wires should totally disconnected from battery earth. It's hard to see how such a simple device could be shorted to ground unless the wiring insulation has been compromised in the replacement process. If it isn't a wiring issue, then my experience has been that aerials (the car type, or otherwise) are difficult to repair without specialised equipment (problem is that they need to be tested at the IF operating frequency), Do you still have the original aerial that you could try putting-back?

I suspect that you will need to fix the error message in the auto-scan report first before proceeding with your substantive issue

hi dv52, it seems too much of a coincidence that the antenna issue popped up after the key issue. but you'll never know. stranger things have happened.

i tried the original antenna no joy.i did see a service bulletin by audi while trawling the internet. let me see if i can find it. i'll try the multimeter as well.

This TSB applies to 2000 to 2014 Audi models including the Q5, R8, A6, A8, Q7, A4, A3, TT, Allroad, A5 and A7.

Central locking via the remote control does not work either sporadically or permanently, but the locks can still be operated manually. Missing synchronization between the remote control key and vehicle may occur because the battery has been disconnected or the battery in the remote control has been replaced. If other senders operate in the same frequency range (mobile phones, TV stations, wireless headphones etc.), the remote control key may have been temporarily switched off because a clear indication of the remote control key is not possible. This is necessary to prevent an unintentional unlocking of the vehicle by other unrelated senders.

Perform the synchronization between each remote control key and the vehicle:

2000-2008 A4

Open the vehicle mechanically with the key.
Press the unlock button of the remote control key.
Insert the key into the ignition switch and switch to the ON position.
Switch the key OFF again and remove the key.
Press the unlock button or the locking button of the remote control key.
Model year 2002 or later: If the synchronization procedure was not successful, adapt the remote control key(s) to the Central Comfort System control module (address word 46) using the VAS scan tool. Follow test plan J393-central control module for comfort system, adapting remote control key via adaptation (channel 21). Sometimes following the “erase all memory positions first” test plan produces better results.
R8, TT, A3, A6

Press one of the buttons on the remote control key.
Lock or unlock the vehicle once mechanically with the key.
The complete process must not take longer than 30 seconds.
Up to and including model year 2009: If the synchronization procedure was not successful, adapt the remote control key(s) to the Central Comfort System control module (address word 46) using the VAS scan tool. Follow test plan J393-central control module for comfort system, adapting remote control key(s). Sometimes following “erase all memory positions first” test plan produces better results. From model year 2010: If the synchronization procedure was not successful, adapt the remote control key(s) to the BCM2 (vehicle electrical system control unit), address word 09, using the VAS scan tool. Follow test plan J519-Vehicle electrical system control module, adapting remote control key(s).
2009-2014 A42008-2014 A5, 2014 A5 Cabriolet, 2009-2014 Q5, 2011-2014 A8, 2012-2014 A7 and 2012-2014 A6

Press a button on the remote control key within the range of the vehicle.
If necessary, open the vehicle with the emergency key on the door lock.
Switch the ignition ON and OFF.

A6, A8 and Q7

a. Open the vehicle mechanically with the key.

b. Insert the key into the ignition switch and switch to the ON position.

c. Switch the ignition OFF again.

1. If the synchronization does not help, check the battery of the remote control. The battery voltage must be 3.0 V or higher.

If the remote battery voltage is below 3.0 V, replace the battery and perform synchronization again.
Check whether there are any interfering senders nearby.
Check whether there are any interfering senders in the vehicle.
If interference was responsible for the condition, explain this to the customer.

tried the above and no joy. a little confused about switching the ignition on and off though, does it refer to the start button or the keyhole ignition.

Unplug the antenna and see if the DTC changes from short to ground....... to short to open or B+

Did you check all fuses?

well, some closure to this fault. i sent it to some guy who claims to know what to do with it and it seems he changed the FET on the convenience board. works great. similar to what some volkswagens guys have been doing to their KESSY problems.
