Dunc Posted November 11, 2012 Share Posted November 11, 2012 Hi Everyone, Went to see a friend of mine this morning and whilst I was there was asked to look at the headlights on his wife's Classic Tdi. One the way home the other day, her headlamps went off. Fog lights still work, sidelights still work, illuminated dash, main beam flash works, but no dip/main. Naturally I checked the fuses, all ok. Found some evidence of melting around the multiplug that goes into the main bean stalk switch, but only on one pin and not enough to mark or distort the terminal, only the plastic, and not enought to affect it easily locating. No headlamp relay on this model it seems, only a weird 'headlamp module' which is one of those lumps of mirrors and mystery that confounds a luddite and lover of clockwork simplicity such as myself... So, any suggestions? Quote Link to comment Share on other sites More sharing options...
elbekko Posted November 12, 2012 Share Posted November 12, 2012 Have you checked the connections at the headlight? They tend to corrode badly. Quote Link to comment Share on other sites More sharing options...
Dunc Posted November 12, 2012 Author Share Posted November 12, 2012 Yes, they seem ok. Neither headlamp works on normal dip or main but both work when 'flashed'. I'm hunting online for a proper circuit diagram to (hopefully) give me a fighting chance... Quote Link to comment Share on other sites More sharing options...

Dunc Posted November 12, 2012 Author Share Posted November 12, 2012 It's not a softdash matey, it's the last of the 'normal' ones. Quote Link to comment Share on other sites More sharing options...
elbekko Posted November 12, 2012 Share Posted November 12, 2012 Oh, a 200TDi then. Can't help you with that... Quote Link to comment Share on other sites More sharing options...

oneandtwo Posted November 12, 2012 Share Posted November 12, 2012 Had this before - the connections in the headlamp switch are not soldered but rivetted from memory. When the switch was flicked to on the moving part of the switch makes contact with a brass contact which is rivetted through the PCB. With age it lifts the contact slightly breaking the connection. The flash part of the system is on a different circuit so not affected by the on/off switch hence that side of it still works okay. I soldered the contact to the pcb as a temporory repair and still works now as far as I'm aware. Quote Link to comment Share on other sites More sharing options...

crowbar Posted December 24, 2012 Share Posted December 24, 2012 The RAVE has all the circuit diagrams for the Softdash. Hi. What is Rave and how do I find it? Regards Crowbar Quote Link to comment Share on other sites More sharing options...
elbekko Posted December 26, 2012 Share Posted December 26, 2012 It's the official LR manual, I think there's a link in the tech archive? A quick google search should bring it up. Quote Link to comment Share on other sites More sharing options...
farmerboy_y2k Posted December 27, 2012 Share Posted December 27, 2012 Needs a new main beam stalk happened on my 200tdi one. Exact same symptoms, only very slightly melted multiplug. But new stalk and all worked fine again. Quote Link to comment Share on other sites More sharing options...

But new stalk and all worked fine again. He's right you know. Stalk = fixed. Now that I've got a Tdi RRC myself, I still want to find a decent wiring diagram though...
