New here, Just bought my Daughter a 57 Reg 5Dr Polo.

Central Locking and the electric windows packed up at the same time, seems to be a common problem. The Motors have only got 1 plug so not the control unit style(well I'm guessing this)
The fault

The central locking isn't working from either door lock when using the key
The central locking is working from the lock/unlock interior switch
When using the interior locking switch the NSF door lock is bouncing & Interior light not coming on when door opened
Both Windows are not working from the OSF switch
NSF window works intermittently - strange thing is it works regardless of ignition lock position (no pattern in making it work)
Interior light working from the OSF

I have checked the wiring in the grommet into the vehicle with no signs of damage or corrosion.

I have replaced the NSF lock and now this will lock the vehicle all round.
OSF door lock still not locking the vehicle and windows not working.

After the NSF door lock mech (one off eBay) was open and closed half a dozen times the deadlock has activated and unable to open the door, you can see and hear the lock unlocking but unable to open the door from inside or out.
I only have a basic scanner but this showed no faults stored.

A member called @john.p.clegg may be your best bet for assistance with the deadlocked door. I've seen a rather ingenious solution to this posted by him on another forum, not sure if I'm allowed to link out to it. It involves making a template and then drilling a small hole from the inside to give direct access to a torx screw which can unlock it.

 

I may be able to help you with the window motor/locking. I have a repair service which I have very recently expanded to include the generation yours is. Click 

Can you read the part number off the driver's side window module, probably 6Q1959801F, or G?

 

Take a look at this ...

thanks, I will have a look later, will this motor still control the circuit like the other motor which seems to have a larger unit attached?

It's the driver's side motor that'll need attention I think, and yes, this version is basically a repackage of the previous generation.

Key position signal still goes via it, so will not register with central controller if module is malfunctioning.
