T6 Front fog light issue

[Shane_Long]

Hi all, I’ve recently purchased a T6 and it has a few niggly issues. I noticed the left fog light come on when Corning and indicating but the right doesn’t. Initially I thought the bulb was out so purchased THQ LED fogs. Same thing is happening but when I put my fogs on they both work. I’m confused! I’m unsure if it’s a wiring issue or a coding issue in the BCM. I have obd11 and no faults come up for it. I’m stumped with what to do next? Any help would be appreciated. Thank you

Initially I thought the bulb was out

Why - was there a bulb out warning on dash?

no faults come up for it

What are the other faults?

I have obd11

What does the output test for cornering lights do? (Abbiegelicht)

THQ LED fogs

Anything different with correct incandescent bulbs?

So I do have the yellow light in the dash but that come back as right dip beam fault. Reading through the instructions with these headlights it does say that’ll come on if my van is a blue motion model and it’ll need bulb monitoring turning of. No faults come up for Corning assist.

Do I have to have a pro version on obd11 to do an output test?

I’ve since turned off cornering assist with obd11 to see if the Corning lights turn off but it’s still doing it.

I’ve also tried turning the wheel full lock both ways a couple of times to see if it would make a difference and maybe recalibrate but unfortunately still doesn’t work.

Is there something in the steering wheel that senses turning left to right? Maybe it’s not picking up turning right.

I have also put the original bulbs back in and swapped them side to side and still no different.

I’m at a dead end really and know of anyone locally that can help me with VCDS diagnostics without ripping me off.

Not sure - please try: OBDeleven > Control Units > 09-Central Electrics > Output test > Cornering light left, right.

Anyways, please check and report first what does OBDeleven report for

OBDeleven > Control Units > 09-Central Electrics > Live data > Channel 35

a) steering wheel centered​

b) steering wheel centered - left indicator on​

c) steering wheel centered - right indicator on​

​

d) steering wheel turned left - 180 degrees​

e) steering wheel turned left - full lock​

​

f) steering wheel turned right - 180 degrees​

g) steering wheel turned right - full lock​

Could you please post full BCM coding - preferably as text.
Should be possible under Control Units > Central Electrics > Info > Press and hold on long coding (on Android anyways)

Please check
OBDeleven > Control Units > 04-Steering Angle > Live data > Steering angle...
a) steering wheel at centre
b) steering wheel 90 degrees left
c) steering wheel 90 degrees right
