Problem with key or starter?

[Arragonis]

Quite a few there - low battery ?

[staffop1]

The fresh air blower is a pre-existing fault I'm aware of where the fan doesn't always work. From googling that error it looks like an expensive fix as the whole fan unit has to be replaced.
Not sure about the flat battery as it was showing 12.1v on the multimeter when I checked.

[Arragonis]

It was just a thought, monitoring in case it happens here...

[MarkTM]

I had half of those showing when my alternator failed...new regulator needed....but my battery was completely dead

Did you save & clear the DTC's several times and were any of them disappearing?

Looking at your scan/symptom you describe concerning gaining entry/starting vehicle my £ is on to investigate J329 Terminal 15 relay.

J329 is Terminal 15 voltage supply relay it is directly linked into J518 Entry and start authorisation control unit plus is part of starter, alternator, starter motor relay circuit diagram.

From what I've looked at it is behind trim where your knee would be when sitting in drivers seat.

[staffop1]

Couldn't see a J329 relay, this is all I have behind the panel in the footwell.


I've fully charged the battery just to make sure and also cleared the DTCs but the component protection message is still there on the MMI and in the VCDS scan.

Problem I have is I can't even move the car or take the car out of 'Park', it's completely disabled!

[gupsterg]

J329 is the SDC code for relay, it will not be printed on relay. If you ask at an Audi dealer parts dept they will supply relay from that code plus cross ref with VIN , etc.

Sorry I should have given you a part number/location on the coupling station, later when by PC will check/post

Although the J329 is clearly diferent in your car.

@staffop1, may I first start in saying I'm just an owner, I have diddly squat professional experience of VAGS .

I'm helping as I hope by helping someone, someone will help me when I have a problem .

Now that's out of the way! what have I dug up for you to do some meddling with!

Red line = J329 , green line is same type of relay from what I've viewed, that is supposed to be J360 High heat output relay and is in the circuit engine speed sender, radiator fan control unit, low heat output relay, high heat output relay, radiator fan.

Next some measuring blocks you could view:-

Module 05 MVB 1 Data window 1 , MVB 3 data window 2 , MVB 6 data window 2 , MVB 7 data window 2 , MVB 23 data window 23
Ref Link:- Audi Portal: ECU Diagnostic . Audi A6 4F (2005- ) . Access/Start Auth. J518

Module 19 MVB 001
Ref Link:- Audi Portal: ECU Diagnostic . Audi A6 4F (2005- ) . Gateway J533

Something about the J329 faults, Link:- Audi Portal: ECU Diagnostic . Audi A6 4F (2005- ) . Without address word J329

Now DTC 00576 is explained as :-

VAG Error Code: 00576

Fault Location:
Terminal 15 - Electrical Fault in Circuit/Implausible Signal - Intermittent

Possible Cause:
Power Locks operating at random while driving.
Radio doesn't turn off when key is removed from Ignition.
Battery drain.
No audible confirmation from alarm horn when arming alarm system.
On the Eos, the front windows may drop down a little if rolled up all the way.

Defective Ignition Switch (Electrical Portion).
Wiring harness issue.

Possible Solutions:
Replace the Ignition Switch (Electrical Portion).
Repair damaged wiring harness.

Now I'm hoping by doing MVB's in module 05 you'll be able to see something which tell you that ignition switch is fine.

In the link for J329 faults you will see replace CU, I'm assuming that mean Control Unit, I did storta read up what CU this may relate to but will hold off for now.

After you cleared DTC's did same faults come up? P/N for J329 4H0 951 253 please do double check this with vag dealer.

PS for other DTC's you can use KeithUK's ( ) great APP Link:- https://www.vwaudiforum.co.uk/forum/s...II-Error-Codes

So this is what comes back from the measuring blocks for Modules 5 & 19:

Not sure if that tells me the ignition switch is fine or not!, I get no lights on the dashboard turning the key..
