Automatic light / rain sensor help please

[steviemajor]

Hi there
Looking for some advice please. I've got a Octavia mk3 2013 elegance 1.4 tsi
Its fitted with auto headlights auto wipers and climate control.
Recently was getting "fault automatic headlight control" on the dash. This only popped up when i started the car in the dark or when i entered a tunnel (went from light to dark or dark to light).But the headlights and wipers seems to work automatically ok.
After a bit of research decide to swap the windscreen sensor (the one behind the mirror). 
The sensor fitted on the car was part number  5q0955547. I was informed its been superseded with 5q0955547b.
Skoda main dealer (Marshalls Gillingham) wanted £281 +vat supply only
As quite expensive decided worth a punt so got one from ebay from a car that was breaking. £25 including delivery. The seller assured me the part worked fine and the car was being stripped for unrelated reasons.
Swapped over the sensor and also fitted it with a new index match gel pad (no bubbles just lucky i guess).
The error has gone away and the headlights work automatically perfectly. But now the auto wipers dont work. Auto wipers are set in the car info screen menu. I tried togging on/ off. 
A friend scanned the car for OBD DTC codes and nothing found. He selected  clear codes anyway.
Any thoughts advice please.
Anyone know If I can i just replace  5q0955547 with 5q0955547b and not have to code the new part. 
Also  friend of mine says he has a spare sensor from  a vw golf mk 7 part number 81D955547 and its does look identical to mine. He says he's happy to let me have it cheap. It was swapped on his car under warranty but did not fix his issue turned out to be his light switch so he's confident it works fine
Maybe i was just unlucky and got a faulty replacement sensor from ebay ?
Cheers

Unless both cars were identical spec, I would expect the replacement to need coding...

 

Maybe refit the original, check the coding, refit the new one and code as appropriate?

Thank you 
Would you or anyone else happen to know what module /component in vcds i would find this coding value.
from what i can see on the web 
 5Q0955547B is (RLHS) and 5Q0955547 is (RLFS)

It's normally a submodule of 09.

Here's an extract from the VCDS scan of my 2016 L&K showing the RLHS as a subset of 09.

I fitted the following sensor to my 2013 1.4 tsi and everything works:

And this is the Address 09 and sensor coding:

Thank you 
Tried a few VCDS "coders" advertised on ebay and got quotes ranging from £60 to £140 to makes the above changes and hopefully fix the wipers.
Sorry i'm new to this do these prices seem about right ? 
Unless there are any experts from this forum around the south east London area that i can meet with and pay instead.  (Any one recommended ?)
Thanks again

I think you can find the list of people with VCDS (somewhere in the forum) and most likely they would be happy to help (you could offer them some drinks/beers instead!).

[steviemajor]

Thank you everyone, will take a look for possible VCDS contacts near(ish) me.
