Factory Led Headlight Flash Problem

[davmil]

My T6 Highline is nearly 2 years old now and its been back to my local dealer several times with what i think is a lighting issue, each time im fobbed off with one excuse or another and am now getting rather irritated.
Heres the situation. If i have my light switch set to manual on the control and only the drl's are on and i VERY QUICKLY flash the lights (for example to thank someone for giving way) only the offside headlight will flash. The only way that both will flash together is if i hold the stalk on the side of the steering wheel back for longer or if the headlights are on when i flash. If any of you out there have factory fitted led's may i suggest that you pull up in front of a shop window or garage door in the daytime and try for yourself as I've got a sneaky feeling that i might not be alone with this issue. Im aware that there will be a millisecond delay between pulling back on the stalk and the power getting to the headlight flash but surely both lights should flash together - just like my Morris Marina did back in the day!

I'll give that ago...

But in the meantime can you catch it on video?

You have a faulty headlight power module, I have had the exact same thing happen to mine and got the dealership to replace the module under warranty, I also noticed on mine that when I switched the headlights on one came on half a second after the other, same kind of delay as when you flash main beam

You can access the screws on the module without removing the headlight so if you want to prove it swap the modules over from side to side and the delay should move to the other headlight

Thanks Pauly, i remember you mentioned before that you had a similar problem and i told my dealership to check the module but they appear to know it all and dont appears to take on board what the customer explains to them!!!!!
The time before this visit they told me that vw had picked up on this fault and said it was a TPI Fault and my local dealer carried out what he called a Terminal 30 Reset and said it was all sorted, but obviously to no avail as the problem is still there.

a Terminal 30 Reset and said it was all sorted.

Ha ha, disconnect the battery for 1 minute and reconnect.....
