FAULTY DOOR MODULE

So I bought a drivers door module from TPS for my Skoda Superb MK2 when my mechanic fitted it all the problems continued. The mechanic later found split wires which he repaired he then refitted the new door module the problems where still  there, he then fitted the original old door module which fixed all the problems and all was back up and running.

The mechanic deemed the door module as faulty and put this is writing. On returning it to TPS with in 10 days of purchase they refused a refund and advised that I make an appointment with Skoda pay for a diagnostic charge and get them to confirm the part as faulty if it is then they will either refund or fit the part for me free of charge.  I have refused to do this as not only is it unfair to me as a customer but it was also not disclosed to me at the time of purchase. I should just be given a refund by TPS as my purchase contract is with them I bought the part from them and it is no longer required.  Can I get them to refund me as per my consumer rights?

You're assuming the problem was with the door control module and by the sounds of it, the module was always fine.

 

Cracking and failure of the wiring from the door to the vehicle is common on the Superb 2 and is the first thing that your mechanic should have checked. The recommended repair is to replace the wiring loom for the door. It sounds like this was the problem with your car all along, and that your mechanic has just patched the existing wiring, setting you up for further failures in the coming weeks and months.

 

If what you say in your post is correct, the problem here lies with your mechanic misdiagnosing the problem and recommending that you buy a door control module that you didn't need. My guess as to why the new module didn't work is that new modules may require coding with diagnostics in order to function - I can't find any detail on this right now, so treat this as an educated guess.

 

I'd guess TPS's reasoning for refusing a refund is that the part has been fitted to your car and removed again. On a car which is now known to have faulty wiring, it's possible for the module to be damaged on powering it up, so without further testing of the part it would be reasonable for them to assume the part might be faulty and refuse a refund. You are the one claiming it is undamaged, so it looks like TPS want you to prove this before they issue the refund.

The new door module needs programmed to car 
so its not faulty just not been programmed 
As above if fitted they can refuse to refund
