Adaptive Light Defective - error

[AL0500]

Hi there,

I have an error on the dash 'Adaptive Light Defective' that has recently appeared.

Code = 02627 Dynamic Cornering Light Motor LEFT (V318) Open Circuit/Short with power. Dropped it past the local Audi Service department here in Sydney Australia (yikes) A$3,700 for a replacement Motor/module.

I happened to replace the globes many months back and I noticed at that time the wiring was in pretty bad condition in the light assembly, I guess there is a part of me that worries this motor/module once replaced may not actually be the issue.

- Has anyone had any experience with this error/issue?
- Would anyone know the specific part# I may require, so I can see if available online?
- Can I assume this part is universal for both (left/right hand drive) ?
- I welcome any comments, feedback suggestions etc...?

Many thanks in advance fellow owners.

Described on the posts in that link is a potential fix for this. It seems that the wires inside the headlight cluster break, stopping the adaptive motor from functioning.

From what I have read there is also a control module. I am unsure if it is sided. If not, you could swap from the defective side to the functioning side and see if the fault transfers.

Many thanks Douglas. hmmmm. I believe this may well be my issue. I'll pull it apart and check for this broken wire + swap motor/module over to other side to see if the fault follows..... ahead of replacing the part.

Again, I appreciate the reply and links.

No problem!

Hopefully it's an easy fix for you

I have the same problem. Has anyone tried to fit a resistor of the same resistance value as the working electric motor, across the power wires?

The resistance of the working motor should be quite low I would imagine and the current would be relatively high. It would need to be a high wattage capable resistor so it doesn't overheat. But yeah, that is the most likely way the car senses if the motor is working (the same way as headlight bulbs are sensed to be working or not) - by sensing if current is flowing in that circuit.

Unless the motor has a potentiometer like device inside it which varies resistance as it rotates, and could therefore tell the car what angle the light is facing. This could be compared with the steering angle sensor and could show up a fault that way if it isn't corresponding correctly. Do you know how many connections the motor has?

[douglas96]

After having a quick look at ELSAWin (picture attached) it looks like it does have a position sensor (G474, which is highlighted in blue) for the swivel motor (V318), therefore the resistor method is unlikely to solve the problem as this sensor will need to correlate with other values (most likely the steering angle sensor). It seems that the only way to fix it is to get the motor working again whether that is by replacing the motor (which I think is only possible by having the headlight cluster apart) or most likely by replacing or repairing the wires that are almost definitely broken or by replacing the control module (J745) if it has failed.

Also I can't understand why this feature was designed so that it can't be coded out with VCDS or the likes. It's not as if it is a critical safety feature like airbags, etc.

Hi, after pulling the lights out and pulling them apart the wiring is in very poor condition, brittle and basically to far gone. I am reluctant to place them back in the car.

I therefore wish to purchase two new headlights. From Audi here in Australia they are approx A$2,600 (approx 1,750 EUR) and come out of Germany with approx 10days lead time.

Given these C6 RS6 are rear in Australia 2nd parts are not available from wreckers etc

Q- If I was to purchase from overseas, are there any differences with right hand drive v's left?

Q - Any suggestions welcome....?

Hi,
Yes the beam pattern is different on RHD cars vs LHD cars and if you were to fit lights off of a LHD car then I would imagine the car would fail it's annual road-worthiness check (MOT here in the UK, not sure what the equivalent is in Australia). I also don't know whether Australian models use the same headlights as a UK model. Although both countries drive on the left, the regulations may be different between the two countries. For example, although both France and the USA drive on the right, their vehicle lighting regulations will be different, meaning that the headlights may be of a slightly different design and would be incompatible.

There are headlight units listed with "AUS'' in the parts list so I'd suspect that they are different to those used for the UK market.

All noted and appreciated. I think I'll just buy via Audi locally.

Or find a skilled autoelectrician who can replace (not cut&splice) the wires - there are few wiring terminals that I've not been able to find a replacement for. I know from my other half's son (who lives in Brisbane) that some things are difficult to source in Australia but if you're looking at thousands for new units it could be something worth looking into.
