3.0tdi Allroad brake fault alarm on switch on.

[sparker]

Hi Gupsterg,

This only happens when I turn the key to position one, when the dash lights come on. If I turn the key off and then one again once or twice the fault goes away. I guess it has something to do with when the modules etc, power up. Once the dash has reset e.g. esp and glow plug lights go out it starts perfectly with no problems at all when running.

I'm thinking possibly that dodgy battery volts/amps, voltage controller or something like that causing the modules to do a wobbly.

Can a faulty key cause any problems as they are a lot more complex than just engine immobilisers, with their memory function. One other thing I have noticed is that sometimes (but not very often) when I unlock the car not all the doors unlock and I have to unlock again. Probably not related, just clutching at straws.

If fault with key I would assume log would show, but if you wanna check some measuring blocks, with VCDS access module [05]

Audi Portal: ECU Diagnostic . Audi A6 4F (2005- ) . Access/Start Auth. J518

Measured value block 11:
Bit 7 ...<--... Bit 0
'0 0 0 0 0 0 0 0'

1. Remote control key '0 0 0 0 0 0 0 0'
(Bit 7-4: (0 = ID sender unknown); Bit 3: Battery (1 = Low); Bit 2: open; bit 1: Rear; Bit 0: close)

2. RRC (command from J518 on CAN) '0 0 0 0 0 0 0 0'
(Bit 7: Wrong response; Bit 6: No response; Bit 5: Carfinder error; Bit 4: CAN Carfinder;
Bit 3: CAN PANIC; Bit 2: CAN Rear; Bit 1: CAN Close; Bit 0: CAN Open)

3. Reception strength of remote control key
(hold remote control key directly against rear window when operating)
If the value is less than 170, check the battery in the remote control and the connection from the electronic ignition lock -E415 to the aerial according to the current flow diagram.

For the last couple of weeks I hadn't had any problems but today the same fault was back with vengeance. I was stuck in the school car park with the dash lights all on, brake fault on DIS and an alarm bleeping but this time turning the key on and off didn't work. The car would not start, my 4 year old sitting in the back asking me if the problem with the car was back. He then sweetly told me he would help me fix it when we got home. After about five mins of turning the key on and off the dash lights came on normally and the car started fine.

I'm sure that when this happens the car doesn't 'click' the same. Normally when I turn the key I here several clicking noises from around the car which I assume are solenoids switching. I think it doesn't sound the same when this problem occurs.

Could a bad solenoid be causing this? Which solenoids come in to use when you turn the key to position 1?

I have read the fault codes again and they are listed. It does seem to list faults which occurred today and another lot which occurred last month. I haven't noticed any other problems when driving the car and have no idea if they are in any way related.

How can I get help from a8 tech? It seems he has a great knowledge of audis and I would really appreciate his ideas.

I'm going on a family trip to France for our holiday next month and would really like to have fixed this before I leave, I don't what the worry of breaking down over there and ruining the hols.

The only person I can think of at mo (no offence 2 any of the other great posters) who could answer such a ??? is a8 tech

Click above link.... send PM...

[a8 tech]

looks like a terminal 30 hanging so all the faults relate to engine ecu

remove the passenger e box cover

located nsf plenum chamber

inside you will see the engine ecu and the supply relays

check for water ingress and feedback your findings

[gupsterg]

Hi A8 Tech ...

Advise sparker to do that post 5... post 7 sparker say

I have checked under the bulk head trim, all dry as a bone, no sign of any water at all. Have check the drains before to make sure they where clear. Also had checked in the rear both sides as I know water can get in from leaking washer pipe (never use rear washer just in case ), also all the carpets seem dry too.

then further data post 20

Removed the cover on the ECU, just as you said the terminal connections have a metal plate riveted over them so it's not really possible to check their fit. Perfectly dry inside though so no damp induced problems.

[a8 tech]

ok need to read drive train can status when the fault happens as well as voltage

get the drivetrain from address 19 or 03 (measured value blocks)

get the voltage supply to the ecu from address 01 if possible

look at

address 19

Measured value block 125:
Engine electronics (no readout/0/1/Sl.Ind.)
Gearbox electronics (no readout/0/1/Sl.Ind.)
Brake electronics (no readout/0/1/Sl.Ind.)

compare findings with

Result: Meaning:
No readout Control unit not coded in gateway
0 No signal/communication or control unit in sleep mode
1 Signal/communication (in control units of the drive train data bus this status is also if there is mutual shorting between the CAN-High and CAN-Low wires)
Sl.Ind. Control unit ready to sleep

A8 hope you don't think I'm being busy body...

As been involved in thread and I know you are busy guy thought would answer your query...

So OP ( sparker ) get resolution quicker...
