Documenting the PN history for the C4 Central Locking Pumps

[UrS4boy]

Part number i have is 8L0 862 257 and just to the side of that it had PP GF 30. I was surprised at how many wires go into it and how big it was.

There is a T10 connector, a T12 connector and a T16 connector on the all singing, all dancing 1997 8L0 control modules, as shown in the attached pdf.

+00001 - Rear Lid Opening via Rear Lid Lock
+00002 - Anti-Theft Confirmation via Blink
+00004 - Selective Locking

Hi Dave, where is the pump situated in an estate? Just been out and looked in the left and right lockers and the pump is not in either location.

Sorry I missed your question (I know you have your answer now but here are the photos I would have posted. The pump is in the foam "box" this side of the battery, both C4 sedans and avants):

I don't think anything before the 8L0 control modules can do very much. The 4A0 modules are very limited. They will close all the windows and sunroof if you hold the key in the door lock in the locked position until everything is closed. But that is about it. No magic or tricks from them, unlike the 97 8L0 modules. So seeing as you have an UrS4 and the 8L0 modules are wired completely differently than the 4A0 modules, you will be disappointed.

Are you sure that key must be held in locked position for windows to close? On my A100 I have alarm, so I just lock my car and windows close, I can walk away(works the same way without alarm) Whereas on my dad's 2001 Skoda (and most cars these days), key must be held in locked position for windows and sunroof to close.

I am talking OE UrS4. On my 93 UrS4 sedan, just locking the car with the Infrared remote does nothing to the windows, etc. If they were open, they stay open. Sounds to me like your A100 has an aftermarket alarm installed.

For example, Right Click (one of the aftermarket remote/alarm manufacturers), covers this in their wiring diagrams and lists:

But even when I removed the alarm, it still works the same way. I lock my car, and the 203 relay clicks and all the windows close. Once I get home (3 weeks time) I will try it on the S4, and see what that does.

Where is this "203" relay and what is its part number?

Same relay we discussed on here

Sits in the red slot



And here is the relay itself





Sometimes it doesn't close, but then relay doesn't click either, which I assume is because of age

When I had my old alarm, it wasn't working as it should, so I took out the fuse to not have it, and windows closed when i locked the car and walked away... but we'll see what happens with the S4, as non of the comfort function work on it atm, relay problem probably, as central locking works fine.

I have documented the Auxiliary Relay Panel 2 (driver's side kick panel) in which the "203" sits before but I have never heard of the windows closing upon locking on their own. Only holding the key in the lock position in the door has done that for me. I don't know if your "203" was working properly or I have missed something in 16 years of UrS4 ownership.

It could be possible that when alarm was installed wrong when my dad bought a car back in 2004. I'll see what happens with the s4
