Im new at this so i really don't know what to do. Lights below doors don't work, also mirror lights don't work and when i lock the doors with the remote one door doesn't lock so i have to lock it with my finger. Can anyone help me or should i go seek help from proffessional.

Read "water ingress problem - solved" at top of Superb 1 forum. 

 

Excellent guide to most probably fixing your problem.

HI yes it sounds like the dreaded water ingress problem. You will probably find water under the front footwell carpets this will have caused erosion on the wiring nodes.

Had mine repaired by skoda dealer and got them to seal the filter box.

Okey thanks guys!

[SkodaSuperbEST]

Okey, so now i think ive found the problem, can anyone tell me what should i do next? do i need to seek proffessional?

That depends on you - if you can do some soldering and the work needed to make sure the source of the water ingress is fixed, you can do it yourself.  There is lots of info in the post mentioned above.  If not, you need to find a good VAG independent - they will no doubt have seen this before...!

oke, thanks

I would have a go yourself, just cut all the wires going into the node and strip them and solder together.. check them all, every one I went to on mine was the same..

Hey,

 

Does anyone know if dashboard and parking sensors are controlled by convenience module? 

 

Thanks

[Cown]

Dashboard yes. Parking sensors no.

Thanks! One more question if you don't mind... Would the convenience module of VW Passat fit the Superb?

[Cown]

No afraid not

[Irmis]

Ok. Thanks for your help!  :sun:

Okey, so ive soldered those wires together. Trunk lights and also lights below mirrors started working but not the lights below doors and foot lights. I cant find the problem :/

That's a good start, fixing that junction has brought back some of the functions, but there are more junctions in that same cable bundle.  If you remove more of the tape that holds it all together you should find another couple of similar junctions near either the front or rear door.  All need cleaning up, soldering and wrapping with insulating tape to get them working properly.

 

Check in the bundle for broken cables too...some of the cables at  the junctions seem a bit short and break.

 

Good luck with your further investigations!
