Headlight Switch Assembly in Dash

[rogerjohnsen]

I've had this problem before with both my 2003 986S and 2004 996TT where the headlights don't come on when I turn the knob to the proper position.  I had to replace the internal switch unit and that fixed the problem.  What I'm looking for is the Audi part number if anybody knows what it is or can point me in the right direction.  It's an Audi part but Porsche used it in these models and charge 4x the cost for the replacement.

I've included a picture as well.  I know the part cross references to an Audi / VW part number; which is what I'm looking for...  Many thanks!  I've searched Google high and low and don't know why I'm not able to find it but had run across a post years ago when I last replaced it.  I was able to find it again for my 996 TT when that one went out but can't seem to find it anymore and would rather not pay the Porsche premium price for a semi-generic part.

Thank you - different part though.

Thank you - I've seen them cheaper but the identical Audi part was around $35 vs. $141.  Doubtful but maybe mine will have the Audi part number on it somewhere so I'll check that too and post it if I'm able to locate it.  It appears to be a common issue and remember the first time I had this problem - leaving the office late one night and my lights wouldn't turn on.  I've seen suggestions about adding a relay to the wire because these go bad from the "arc" created on the terminals when power applied.

Hmmmm - Audi had a recall a while back due to the part shorting out and replaced it with the newer module and a wiring harness to mate the old and new design.  This probably explains why I can't find the Audi part any longer and perhaps Porsche didn't get the memo?  I can still find the Porsche part all day long - just no Audi comparable; which makes sense to me now...
