Hi all. Been lurking here for a while getting plenty of inspiration from other's tweaks and tips.

Probably wouldn't have tried or even thought about half of them if it wasn't for this forum, so thank you all.

 

I fitted the H&R lowering springs over the weekend and I'm properly chuffed with the results.

Only issue is the auto levelling headlamps. I guess the car now thinks the boot is loaded so drops the headlamp aim level.

Any pointers as to a procedure for resetting them? (I have OBD11 if needed).

 

Thanks in advance,

Tim.

Hi Tim, surely that would only happen if you only lowered the back? If the front and back are dropped by the same amount I'm sure it'll be fine.

Hi MeteorOcty, the only position sensor on the suspension I could see whilst swapping the springs was on the rear left. 

I can only assume front ride height isn't affected very much by varying loads in the car, hence not having any height sensors there.

 

Therefore, with the rear sensor reading -25mm it thinks the car & boot are pretty well loaded up and lowers the headlight aim.

I drove into work this morning in the dark and the dip beam aim was a lot lower than before the springs were fitted.

 

Cheers,

Tim.

Yep, mine seems to  need a tweek now it's lowered.  I figured it was just because the lights are now lower to the ground they don't show as much of the road as before...

If you need to adjust the height of beam manually, there's adjusters on both of the headlight units which only need an allen key to adjust.

 

I did mine when I got my car as the headlights only illuminated a few meters in front of the car.

 

IIRC clockwise is higher and anticlockwise is lower (though it may be the opposite). Just make sure you turn them both the same amount of times so they get raised equally.

Thanks for the info tunedude, is it that simple?

From what I've read I was under the impression I needed to either reset the lamps zero position, or put them into 'adjust' mode before tweaking the height adjusters.

Yeah, that's all I did. It got a couple of attempts. The first attempt saw me lighting up the sky and the second had me back down to floor. Third time's a charm.

 

I've probably got them a smidge too high, but I like having the beam a little higher to light up the road on the side of the road.

Thanks tunedude, I tried the other route......

I found a video on youtube explaining the reset procedure on OBD11, so gave that a go last night. 

Worked a treat and headlights back to their previous awesomness!

 

Was under:

Headlight Regulation (module 55)/

Basic Settings

then apply 'Basic Headlamp Setting' followed by applying 'Acknowledge Basic Setting'.

Did you have to manually adjust the lights with Allen key or whatever tool required to raise them up??

 

Interested to know!

 

thanks

Whilst this works, in Lumox7s case without resetting the zero position properly, the lights will believe they are as low as they can go and similar for the suspension sensor, meaning they will no longer correctly self adjust to account for rear biased loads causing the headlight aim to be too high whenever something is in the boot.

 

This sort of adjustment should only really be used for small tweaks to account for the fitting of the headlight unit or the bulb being slightly off. 

 

What Lumox7 has done is the correct procedure for resetting the lights after a change to the suspension setup.

Nope, I just sat in the car and reset them through OBD11. No need to lift the bonnet.
You hear the headlamp motors moving around for a few seconds and then it was all sorted.

 

Cheers,

Tim.

Yeah @tunedude You may be setting yourself up for an mot failure if they are not set, and adjust correctly i think, if you did that with self levelling xenon,s.

 

I had adaptive xenon's on the A4, but they never did the dance. will have to look into it one day.

Mine still adjust themselves on start up and the turning ability still works.

 

It's only a minor tweak to adjust them if the MOT bloke says there's a problem.
