  1. He said they used to dip, so I'm assuming it was there to begin with................. Check the wired (not the fixed) connectors on the back of both light units. If either of these has a loose connection or a pin not making contact then neither of the lights will dip. Hope it helps, good luck...
  2. Reading the Bentley manual it seems that it is necessary to have a PST2 thing connected before the brakes can be properly bled on a PSM equipped car (2001 S). Is that correct? ie., can a good solid pedal be obtained bleeding manually? Or is there any other altenative to a visit to the local Porsche dealer? David
  3. Thanks Toolpants, checked the headlight units and the left side unit was not connected. Re-assembled and tested - both sides now motor up and down with the dip switch, ie., it looks like the left unit controls both motors. Maybe... Thanks again, David B) I thought this was a bit too easy... Switched on lights tonight and neither adjuster motor is working again. Checked connectors in both headlight units and both are connected correctly. Is there a relay somewhere? or a fuse? any other ideas? Does anyone know what voltages should be on which pins? Or where I can find a wiring diagram? Thanks for any help. David More checking, both light unit 4 pin connectors have about 3.6volts on all four pins whether the lights are on main beam or dipped. I've found the control unit for them behind the front boot trim next to the m'cyl reservoir but it has too many pins to check without a diagram - but it definitely has at least one pin with 12v on it all the time the headlights are on and one that has 12v on it when on main beam that goes to 0v when dipped. So to me it looks as if the control unit is getting power and a signal so is probably faulty? I guess I'll need to buy one to find out... I'll let you know. David OK - problem solved I think. The control unit is not faulty. What was wrong was a bent pin on one of the adjuster motor connectors preventing the socket from fully engaging and getting an intermittent connection. What I didn't understand was that the control unit doesn't work if any one of the adjusters is disconnected. ie., if one headlight is disconnected then both motors stop working. Out of curiosity I've checked and disconnecting one side at a time (doesn't matter which) causes both motors to stop working. A bit counter intuitive... Now for some beer... David

  7. I recently bought a 2001 S with factory litronic lights. As this is the third car in the family with xenon lighting (Focus ST and Mazda 5) I was expecting the same superb lighting. When dipped the lights look reasonably good but on main beam they are disappointing to say the least. There is a really dark spot right in the middle and the foreground seems very bright. On main beam, all the bulbs (including the H7s) are working but I've noticed there is no trace of movement from either of the litronic adjuster motors in the light units. I'm guessing this is the root of the problem. Anyone any ideas how this system is supposed to work? Does the level sensor look at car rake angle or is it simply a reference from horizontal? If so, how does it know when the car is going up or down hill, when braking etc? Any other ideas what might be wrong? Thanks. D
