That might be the case for the rear wiper, however the Passenger side lowering on reverse is down to a CAN signal.

As your issues are after he did work then you need him to sort it

Get the car scanned to see if you have any faults where did you go to have it fitted? and was it an original Skoda or aftermarket camera? all functions should work with no conflict

Just had a look at various build combinations and years and some cars use the extra wires for the remote control and some don't. Pulled my passenger side A-Pillar trim off and couldn't see the wire in the loom. Looked at 1K0 937 085L on the parts program only shows replacement to be used 1K0 937 087AB has PR-Codes 4R0, 4R4 and 4R5 no info about remote control

If the BCM does support remote locking or if it is changed then the wire will need to be added or the remote range will be very short It shows up as R47 BCM pin outs T52/C pin 41 for HF T52/C pin 40 for shielding

Cheap Mod Newer style Screenwash cap

You would also need to add antenna wire to the bcm Another thing to consider if you change the bcm are the rear doors Some BCMs control the rear door locking and some use the LIN from the front doors for locking

where are you located? do you have a vcds autoscan of your car?
