For a number of months now my keys have not worked the central locking so i have had to use the key to enter my car. My brother has a copy of vag-com so ran the normal tests and everything suggests it should be fine but the key simply wont programme. It flashes when tested but for some reason wont go any further. So recently we ve tried to resolve it and last week we had a look at the convenience module in the boot which was soaked after a leak from my rear washer. I had to change the module at a cost of £200 and we thought this would resolve the problem but still no luck. We know a guy who works at SEAT who has the same equipment as audi and he tried to programme the key to the new module but again the same problem. All of the tests on the key suggest it is fine but I have just ordered half a new key (dont need the blade part) from Audi and am hoping that will resolve the issue. If not then ill have to go to audi and let them investigate but id obviously rather avoid that as that will cost the earth! Has anyone else had similar problems or heard of someone who has?
