When high beams are activated the projectors do not tilt up

Why are the Mk3 face-lift's LED headlights better than the Mk4's?

The more I hear about the MK4 the more I'm sure it won't be my next car.

Reflash the ecu should do the tricks. I assumed before they handed over the car they did a software update and not followed the documentation correctly. If you would have a obd11 you would found some error in headlight module and central unit

I'm coming from MK3 seat and the MK4 led a much better. But needed to be adjusted as from factory they were too low
Same with the adjustment on the MK 4 but I find the projectors don't seem as bright as the MK3 face lift lights, but yeah the original MK3 lights were really dull.

My FR, glad they finally admit it's an issue.

Hi Guys,

Just an update to say that the issue has now been fixed by the dealer. They applied a 'Software Update To ECU Ref: Headlights Issues' which has sorted the issue.

Thanks

Glad you got it sorted, although the dealer's original response "that's just how it's supposed to be" demonstrates how much you should trust anything from a dealership.
Some are definitely better than others, but you're right. Too often it appears they patently just can't be bothered.
From the description of the fix given by the OP, it appears there is a Technical Service Bulletin covering the issue. Obviously they hadn't checked for that originally.:rolleyes:

Hey I have the same problem as you had, It worked really fine till someone coded for me to unlock some options and then unfortunally the projectors don’t tilt up anymore, just the extra LED elements are coming on and it doesn’t light up as much as before. The ObdEleven log in is attached.
Thank you.

I wonder if its the same procedure for matrix lights? I have matrix led, and there is no tilting just the matrix coming on? Normal I guess?

Hi All,

Just an update that I have taken it back to the dealer and re-brought up the issue which they have now acknowledged there is fault with the Headlights not raising (tilting up) when high beams are activated, and will be investigating this next week.

I'll let everyone know the outcome once they have formally diagnosed the issue.

Thank you everyone for all of your advice.
I have the same issue.. I'm not convinced my dealer knows what is going on.. MY main beam is basically dipped, but brighter. I don't see any raising of the main beam as described. Does anyone know what I can tell my dealer to look for, or the most likely cause ?

Hi, for me the problem was solved, I took it in for a problem with the roof not opening and the lights came back as they were, I think they just have to reset the ECU or something like that.

@Martineric96, did this get resolved? I have a MK4 Leon with the exact same issue and my dealer is struggling to resolve it. SEAT UK Chat has recommended a full diagnostic check.. I am waiting on this to be done - booked in end of Nov.
Looking for any info that I can pass to my dealer...

Thanks
