2002 Passat. The dealer is giving me a hard time

Convenience Control Module Where do I start, this is a bit long winded, but worth the wait….
Back in August 2008, my alarm started going off at all hours of the day and night and often I would be driving along the road with the alarm sounding as I went. After several days of checking fuses and relays etc I booked it into a reputable VW specialist in Totton, who proceeded to charge me £75.00 for the privaledge of telling me it was probably the Convenience Control Module (CCM). At a cost of £207.00 I could not afford one at the time. As the days and weeks past my electric windows stopped working and remote gave up, interior lights stopped and clicking came from the passenger foot well. On finding this website I began to do some DIY and located the looms under the passenger foot well everything that was supposed to be there was there. Unfortunately there was no corrosion, I wish there had been.
This is where it gets better. It is now October 2008 and I am threaders now, so I speak to the original garage that did the diagnostics and they were going to charge me £337.00 to purchase and “program” the CCM. I then rang VW Parts department in Southampton and ordered the CCM at a cost of £207.00, they then diverted me to the VW servicing department who then told me it required programming at 2 hours work that will be £275.00 fitting, VAT, and labour. I nearly fainted and told them that I was not interested in their high charges and that I would seek fitting elsewhere.
At this point I rang another reputable garage in Durrington, who had helped me out in the past with another problem, they were going to charge me £40.00 + VAT, that’s better so I booked it in. I collected the CCM from VW parts and connected it up, the windows worked perfectly and the interior lights worked fine. The remote and alarm obviously needed programming so I waited until the Saturday morning for the inevitable “programming”.
Nearly finished. I waited at the garage whilst they took it in and after 10 mins returned and asked for my spare key, which of course I did not bring. They said therefore that they could not program the CCM etc, however, I could do it myself… What? I said. All you need to do is place one key in the ignition whilst using the other one to lock the car whilst pressing the lock button for about 5 seconds and then do this with the unlock button also for 5 seconds and then repeat with the other key.
They didn’t charge me for the advice or the 10 mins they had already spent on it. I returned home and “programmed” the CCM and the remote works fine and the alarm works fine, everything works great. I was livid and angry that the 10 seconds worth of work could have cost me £275.00 by VW who said it would take 2 hours worth of labour.
I realise that they have to make a living but that is taking the biscuit surely. If this helps just one person then it is worthwhile.
