A4 B8.5 NCT failure - Xenons

GTE · 27-04-2019 01:41PM #1

Hello,

A quick one here (I hope).

My A4 just failed the NCT. The passenger side xenon is pointing up and failed but the drivers side is fine and passed.

I had an issue with both lights pointing up as high as possible and traced that down to the rear passenger side leveling sensor arm which had snapped.

The fixed sensor arm appears to be fine (drivers side passing seems to say so too).

Would this be a simple adjustment?

I had them adjusted by Atlas once and they made a right pigs ear of it.

Im hoping to rule out a mechanical fault with the sensor.

Thanks!

They need to be adjust with VCDS, you have to put the motors into neural and then re learn the new position, i doubt any atlas etc place realise this.

Yeah, a good place near Blanchardstown got me out of that particular hole last time.

I suppose the lights would naturally need to be realigned every couple of years? I have jumped the gun to something being quite wrong so I should pop back to that place first.

Have you got a xenon range defective warning on the dash?
