User Name Remember Me? Power Distribution Module J toasted? Here's the short story I've noticed this happens when the "key ON in ignition" chime doesn't chime.
When it happens again, VCDS can't communicate with those modules again. I'm leaning towards a toasted J Module the one under the steering wheel with the relays but not too sure Any ideas, anyone??? Double check all your fuses burn't fuse can cause no communication Then try doing a capacitor discharge - Disconnect BOTH battery cables, touch them together. NOT while connected to battery.

Quick update: All four windows are going up and down now the driver is going in reverse of the button though for some reason. Could it be the fuse I pulled out to keep the radio from eating up my battery? Now a Hundai Tuscon. Not a single squalk in 10k miles. I know it sounds silly Check your alternator.
Either over-voltage or more likely a. My son's Sportwagen developed something like this not too long ago. All dash lights and instruments went out. If you shut the car down all would be well when it was restarted, but not too long afterwards the same failure yet again. In no case was there a battery warning or anything else. All this the end result of a failed alternator. The only code set was for airbags which we cleared with the VagCom.
No damage to the car whatsoever. Good luck. Originally Posted by nord. Most shops will only see the d.

If this happens to be a repeatable problem and you can stay fairly near home base I'd suggest disconnecting your alternator and going for a drive. By that I mean the wiring, not the serpentine belt. If the problem disappears you can be fairly certain that you've found the root cause.
If not, then you've got a reasonable chance that all is well with your charging circuit. One more point before I take my leave You don't by any chance have a v outlet on the vehicle, do you? If so, then I'd look at the inverter.Remember Me?

I don't know how to attach an image off my pc to the forum? Essentially, the wiper motor and rain sensor are not found as sub systems.
The wiper motor has been replaced and is a brand new Audi part. Plugged in, not plugged in rain sensor also and even old unit plugged back in make no difference to the fault report.
I checked all wiring before and after plugs and all is good. Both wiper motor and rain sensor have power, ground and a LIN signal of sorts. They have continuity between each other and pin 28 of the J When I go into outputs, I can move the wiper stalk and see the module behind the steering wheel on the canbus is switching correctly. So I think the J maybe faulty, possibly after the garage that brought it to me jump started the car a couple of times.
Originally it came into them with a stuttering wiper motor, but once replaced it was all dead. I have bought a brand new J from Audi, after giving them all my software and hardware numbers from VCDS and now have no clue what to do to install it. I understand the 'normal' coding eg for parts of the world its in etc but not anything else. I also understand I will probably have to reprogram the remote locking off the key. After having to wait a week for the new J my customer is getting pretty annoyed now so I need to do it right!

Thankyou Bruce I'd like to sort it myself with VCDS if possible Can you please post another Auto-Scan with the new J installed? With new J installed it will have Component protection activate and most electronic will not work till it adopt CP. MartinsX liked this post.
Hello, yes that's what I'm wondering. I know how to do the 'coding' part to adapt it, but what to do about component security. Can I copy and paste or what is the procedure? I can't do another scan now because of the time constraints on my customer I have had to have someone dial in with geko online and deal with it.Please contact our customer service department with questions.

Audi A3 Onboard Control Module J519
Currently I have 7L5 D installed, but it's equipped with not so much additional funcions. Could anyone help me in choosing the correct J module? Electric diagrams in Touareg are the same like in Cayenne, so everything should fit.
Regards Bartosz. Please post an Auto-Scan so people can see exactly how this vehicle is equipped and configured. Originally Posted by barkas. Dana liked this post. Originally Posted by PetrolDave.

When I got to Illustration it shows " 10" Control unit Vehicle Electrical System and that looks like a J unit to me. Hopefully someone else can add clarity. Thank You Dianalink from your post is for another version. If you have a HEX-V2, please click here.Removing and installing onboard supply control unit. The onboard supply control unit -J is fastened to the rear of the relay carrier in the driver side footwell and performs the following functions in the vehicle.
The following illustrations show removal on a LHD model. Removal and installation of onboard supply control unit on an RHD vehicle are performed using the corresponding mirror-image procedure. For reasons of space, the fuse holder has to be removed from the relay carrier but can remain connected. The following illustration shows the installed onboard supply control unit on the rear of the relay carrier.
Pull the two clips of the primary locking system downwards in -direction of arrow- and pull the two connectors -A- and -B- off the onboard supply control unit -J Press the two locking buttons and pull onboard supply control unit -J out of the holder, starting at the bottom.
First insert the onboard supply control unit -J into the top mountings on the holder and then push unit into catches at bottom until it engages audibly.Here is a post focus on Volkswagen J electrical power supply control unit instruction,if you are want to know J module knowledage,it is a point to get.
Until now control units and relays functioned at different locations in the vehicle. In the onboard power supply control unit, these functions are now localised. Furthermore, the following switches and signals are processed and sent via the CAN bus to other control units. Fitting location of onboard power supply control unit and entry and start authorisation control unit.
Furthermore, the onboard power supply control unit deactivates convenience system consumers and long-term HT consumers e. If the onboard power supply is placed too much under load, the idling speed is also increased. This ensures that there is always sufficient energy to start the engine. Switching off is inline with the guidelines for the Volkswagen Phaeton and is described in Self-Study Programme The petrol engines of the Volkswagen Touareg all feature a priming function of the fuel pump so that enough pressure in the fuel lines can be built up.
This then actuates the relay to prime the fuel pump for approx. The priming function of the fuel pump is stopped when the ignition is switched on. Continued actuation is done through the engine control unit. If with the ignition switched on a crash is detected, a signal is sent from the airbag control unit J via the CAN bus and the fuel pump is switched off immediately.
After about 5 seconds. The interior lighting is actuated by the onboard power supply control unit. The voltage supply comes from terminal 30G. To prevent discharge of the vehicle battery when the interior lights are switched on, power supply from terminal 30G is interrupted in the following circumstances:.
Note: If a crash is detected, the interior light is switched on immediately. After the ignition is switched on and off and after is has been switched on again, the cut-off function from terminal 30G is reactivated.
The basic equipment comprises a DE headlight with H7 halogen bulb and a H9 halogen bulb for main beam. On this version, only the headlights for additional main beam flash when the flasher unit is actuated and the dipped beam is not switched on.
A brief actuation of the xenon lamps,e. The turn signals are cool blue in appearance but flash yellow when they are switched on. For the rear lighting of the vehicle, rear light clusters with bulbs are used. The rear light clusters are split into two parts. Government regulations require, in Japan for example, that the rear fog light is switched off when the vehicle is in the highest position. This function is available for other countries as a code in the onboard power supply control unit.
To prevent the surround lights from becoming damaged by long periods of activation, a protection feature is integrated in the onboard power supply control unit which switches off the.
The duration of the coming-home lighting can be set between seconds. After 90 seconds, the lights are switched off automatically to avoid discharging of the battery. In the set-up menu, the day driving light function can be switched on or off. This option is only available in countries where day driving lights are not a legal requirement. The headlights are designed based on the principle of sliding drawers. They can be pulled out.Please contact our customer service department with questions.
