Offside head lamp on 993 C2 1996. How do you adjust the main beam,as it has failed an MOT on being too high?

I can't recall how to adjust but have you checked that the up and down rotary switch in the cabin is having an effect ?
I checked mine when I was getting flashed by oncoming drivers and found it had stuck in the high position. Removing the headlight units and cleaning the contacts restored it back to operation. Worth checking first.

you could let some air out the tyres on the opposite side,level the car up a bit 
But seriously, in the front luggage compartment on the inner wings behind the carpet,you will find the metal release lever that lets you remove the headlight,just behind that you will find a black plastic flap,if you lift that up,behind it there are 2 allen heads that adjust the headlight alignment,they are set back quite away so you will need a long allen key,the heads are quite a soft alloy,so make sure u have a good fitting allen key,as its easy to strip the heads if your not carefull. I think there is a bit about it in the owners manual,but im not 100% sure. As a point of intrest,u said it failed on the high beam ? If it only failed on high beam and not low beam as well, it could be that the high beam bulb that is not sitting in it seating properly and thats you prob,if thats the case its a well known problem with the retaining clip and Porsche issued a tecnical bulleten regarding a fix and the new part you need.im sure there was a bit on here about it a while back.anyway hope that point u in the right direction
