Hi all, 2003 superb headlight problems..my passenger headlight bulb is gone, while removing bulb I noticed bulb holder is loose, can it be fixed?? Is it easy to remove headlight as seal is gone,, condensation,, just want to repair it??? Any pics???

Water ingress problem id say under passenger footwell carpet..see water ingress at top of page...on the 23 pin connector going into ccm the dash display is pin number 1 Brown/yellow, and on the 15 pin connector plug, dash display is pin number 5 Brown/red...

I had 1 that did same thing, it was the egr, they clog up with carbon and flap in egr is restricted by build up of carbon..search cleaning egr,,, ps some sites say brake cleaner is ok to clean egr, but your better off juSt getting egr cleaner,,same price better job.

If u take out pollen filter you can see a flap under it sometimes this flap gets stuck and heater stuck on recirculation mode causeing very bad condensation in car,, on my last car passat same as superb, u just lift bonnet, remove plastic piece were battery is, remove pollen filter under say left wiper, put yr hand in to flap and give it a gentle push in a bit and that will free flap..re,,,no condensation...pollen filter back in, battery cover back on etc etc...or yr pollen.filter seal could be gone, resulting in water getting into floor under carpet, search,, water ingress,, for a how to fix..

All sorted now and everything wrking..thank you everybody for helping.. There was a fault on main power supply to ccm,, got the pin diagram, did continuous test on wire and half way back to plug at footwell under the wire wrap, all corroded, sum1 probed it before and never sealed wire insulation back up.. Thanks again and if anybody needs help I think by now im expert on this problem..also paid for the hour at erwins and printed off wire ddiagrams...great help...can test it now tomorrow..

Thanks

Thank you JIMBOF,, iv spend couple hrs on web searching for this and couldnt find it..from this I shud be able to find my fault..iv been told that under steering wheel were relays are, there are a couple of fuses that have something to do with the CCM, is this true??? Also just asking to know , THE RELAYS,, do any of them have anything to do with the CCM??? Just iv read on web on one site to check those fuses, relays.... When I purchased car there was no owners manual with it,but iv had Passats and know them quite well,manuals also unfortunately... Also on the driver side door piller interior, theres a button about a foot up from floor, on it a picture of car and wat looks like, say, WiFi sign upside on it..what is this button for?? Thank you for all your help briskoda,s

F##k the 1 day I dont have my credit card with me..get it this eve,, thank you

Cant get that done till Monday,no Tuesday as Monday St paddys day and test tomorrow and with work i cant get away to try an other garage..if I could just find out which wire powers the ccm I,ll spend the evening/night working my way backwards from it and hopefully find a fault..

Iv test for car tomorrow afternoon, I can get vag-com but not until Monday as mechanic busy when im free.. Is there any chance u might know wire/voltage that powers ccm unit as I dont want to miss test..at least that way I can maybe see if power is getting to it etc..or ideally a wire diagram for ccm

Yes I opened up ccm.dry, clean, free of any corrosion...I repaired all the connections front to rear even those two canbus connections but I did undo those wires, separated them to cut strip etc..did these hold memory for ccm??

Im nearly 100% ccm is ok as it was dry, no corrosion,, and wen driving around playing with window switch odd time window gos down.and up also rear passenger door overhead light works.. Is there a way to test it,, does anybody know which pins on connector block bring in/out power supply how I can check voltage... Suparb,s are hard to find in breakers yard and dont or cant afford a new one right now so if I could find a way of testing it that would be great... Getting seriously ****ed off now as my last car was a Passat 2001 which had same problem and really really cant understand how vag can still in this day get away with it..if Japanese it would be worldwide recall...joke...also car is in mint condition otherwise engine gearbox etc 100% so dont want to get rid.. No keyfob working No interior lights except rear passenger overhead. No boot unlock from fob or cabin only with key.. Central locks work on turning key in lock but not on fob. No sunroof power. No power Windows but work odd time if constantly messing with switch.. Also if I unplug ccm and then plug back in, hazards come on and off for maybe 10/15 min I think to reset alarm etc so I think it is working. Radio instruments display, driver door power window switch lights and top dash display(radio station) flicker while driving... IM TOTALLY LOST AS TO WHAT PROBLEM IS. And more I look at it the more annoying it gets. Im starting to think I have a bad earth somewere...also think I may cancel my test for Friday as I dont think ill get it sorted unless a genius posts a helpfull reply... Thanks all for trying to help

Cant with work this week and test on Friday...does anybody know of pin diagram or know what pins are live feeds to ccm?? Or maybe a way to bypass for now to get Windows etc working for test? Iv tested voltage of wires going into the block connectors, some showing 12/13 volts others zero volts..so if I knew wat pin should have power I should be able to figure it out I hope.. Thanks for replys..

You dont its ok, id say the same myself..im 100% sure I got all connections sorted as I removed all vag wrap from cables, then slowly. Unbunched cableing into sections so to speak and removed rear seat carpet.. Im sure I got all connections. I even cut back Brown earth, New fitting rebolted it down..I took my time, did it right
