Headlights code: 8IY

Hi,

My apologies for the long post, but I don't want to omit information.

I've got a lighting problem on an Audi e-tron and I'm not 100% certain to condemn the onboard supply control module J519. Customer drove the car and suddenly there was a lighting warning and other cars started flashing at him. He had no front lights. Also the wipers didn't work around that time, but now there's no problem with the wipers.

After some research I found that the J519 module had some water ingress (plenum drains were clogged, but surrounding of J519 seems dry), so this increases the chances of hardware failure of the module, but the following makes me doubt it:

When no lights are switched on or only parking lights, the power supply to the LED headlights (code 8IY) is missing from the J519 module on terminal T73a pins 64 & 65 for the left headlight. (And probably also right headlight on connector T73b) Due to the missing power, there's no high beam when requested, no turn signal lights in the front headlights and no communication with both front headlights. BUT if low beam is on (manually or auto-switched on due to low light conditions) there is power to and communication with both front headlights! Power supply to T73a pin 66 (KL30) and ground (pin 63) are present.

According to the wiring diagrams for the 8IY code LED headlights, the power is supplied only via these two pins on T73a (left) and T73b (right) which are combined in a splice B317/B318 to a single power supply to the module, see wiring diagram. CAN communication seems normal in both cases, no signal disruption/distortion.

On the connectors of the J519 module only corrosion was found at pin 19 on T73a (middle connector), which seems to be a circuit 15 supply signal ("SIG15"). Also some signs at the bottom of this connector, but no green stuff.

My problem to condemn the module hardware is that if the hardware is at fault, I would expect no power at any time to the headlight module(s). And the problem is present for both left and right front headlights although the circuits seem to be separated within the module and connector (T73a / T73b). It feels more like a software and/or coding problem (maybe caused by voltage fluctuations due to the water ingress?), like the FRM modules in BMWs. Does anyone have any experience with both headlights failing unless low beam is on?

Any tips for further testing?
Remote (re-)programming/coding is an option, but also costs a few hundred. But it’s also a waste to throw away a good module if recoding would fix it.
I don't see any codes for short circuit protection. One of my thoughts is that there's another item in the front headlights J519 internal power circuit, which is not activated with low beam on. But when it is on, it causes a failure detection to shutdown the power supply to prevent overloading? It feels like an emergency mode, although I would expect the turn signal to work too. If low beam is switch off, there's no power from the BCM J519 to the headlights, so they're unreachable with corresponding DTCs in the gateway.
Maybe I will open up the module again and do a thorough clean again.

Thanks in advance!

Kind regards,
Geert

In module A5 (Frt Sens. Drv. Assist (J1121)) there are 9 faults codes, of which 4 show an internal voltage of 0V in the freeze frame data. But these are U-codes about missing CAN messages, so I don't know which internal voltage it references to. Could it be that also a power to J1121 is missing?

On Q7/Q8's there is a TPI/TSB for a part of the wiring loom under the plenum chamber cover wearing down leading to all sorts of potential faults (wipers being one of them, i think one or more LIN-bus wires run through that loom). There might be something similar for your E-tron, depending on which generation/platform it actually is.

Hi MasterTommy,
Thanks for your reply.
It's based on the Q8 / MLBevo platform. The plenum is indeed a point of attention for these. I couldn't find any applicable TPI/TSB when searching Alldata.

My problems doesn't seem to be CAN-bus related as the CAN-bus waveforms stay clean, but the power from the J519 to both head lights is missing at the J519. This feels strange as left and right headlights are powered via then J519, but using different internal circuits: fuse SA3 is used for the left headlight and SA9 for the right headlight. Thus as if the J519 doesn't want to power both headlights, only when low/dipped beam is requested. As it's a terminal 30 circuit, I would expect it to be always powered on. And if there was a broken component inside the J519, I would expect it to never receive any power.

I would login to ERWIN and view TPI/TSB's based on the cars VIN.
