Spot the difference
I decided to fit updated headlamps with the aim of improving illumination and visibility. These 'pre-xenon' types are made by ZKW (Austrian) and have a flat, transparent, glass front, compared to the original Hellas. The look is perhaps improved, but not yet sure whether they are noticeably brighter. I had thought these lights would be the type with internal lenses, but that is just for the xenon versions.
It's also obvious where the adjusters have failed. (I am thinking, however, that it could be repaired).
Hi Arnie,
Very interested in this post as my headlight adjusters have also failed. What year is your G? Are these the hydraulic adjusters in which case I understand that they are not fixable - and cost of new is £250 plus VAT (Gav).
Probably very rare to actually use them but if it's a job that I could do myself then it would be nice to have everything originally fitted in working order.
Please let me know what you decide to do and how you get on.

I've read of people using electrically operated adjusters. Trying to repair/replace the existing system is probably not cost effective. It's probably one of the first items installed along with the wiring looms during production.
Yes too much work to extract everything and re-route the new ones. The electric adjusters from the Vito seem to be the alternative.
However, if the tubes are a standard pneumatic, nylon hose, size, then commercially available fittings would allow you to cut / replace/ repair and rejoin as necessary and to re-fill with fluid.
The lights are from the parts dept of MB Dealer at Brentford.

I think you can also use a system from a sprinter van

i understand that it's a sealed system and so comes as a complete set with rotary knob and two adjuster pistons. If it were just a case of paying 250 for a new one, that would be great, but I imagine that it would take the best part of a day to thread through the system from under he dash, along the engine bay and into the first headlight and the across the front cross member, over to the other light.
I was thinking of using pneumatic nylon lines - which is what the existing ones are - and push-fit connectors to make a way of refilling the system (antifreeze/water mix) with enough height to expel air-bubbles and at the same time patching-up the cracks on the adjuster piston with epoxy. Hopefully the piston and seals will be OK.
