Please help, just brought a 2013 superb greenline, issue I got is the back right door, the central locking, window or light does not work like bow power going to it, but speaker works, so I’ve tested the wires loom with a tester to make sure there’s a circuit and that’s all show and inspection what I can see of the wire loom looks fine, I’m not sure if it’s the door module that’s gone, is there a way to test it, does it need to be programmed into the car, then on to the second question, what scanning tool do I need to get to be able to program stuff like this in, really don’t wana have to pay the garage loads of money when I can invest in one my self, I’ve had a look seen loads and to be honest not a clue which one will do the job.

So sorry for the newbee questions, just wana get the car working right and not have to spend a load of money on it.

Thanks in advance

Very good chance that counter intuitively, the issue is actually in the driver's door loom. That's the one that takes most wear and tear as door is opened and closed most often and that door I believe contains a controller that is linked to other three doors. Hence damaged wire in that door loom can cause issues in any of the other 3 doors.

A system scan would help pinpoint the issue, or at least confirm that not a issue with controller itself. Needs a VAG specific solution to be able to interrogate all the car's controllers e.g. Obdeleven or VCDS. There are Briskoda members with VCDS who can help, worst case in exchange for a beer token or two. There may be one local to you -
