Okay, I have calmed down enough now to post my experience of trying to replace the car visa card in our car documents.
I tried to book an appointment online for the visa examination. Managed to get through all the pages until the one where you enter the 'Trafik' number and then it said there was 'money' otstanding on the car and so could not go any further[

!] So the 1st stop yesterday was the tax office. Went to the desk you said Brian, no problem there as that is the form you get to state there are NO outstanding debts on the car. Got that form so there are NO oustanding debts on the car[

!] The only thing I could think of then was because the visa card was full. Off to Traffic Police office where I waited behind some Takobci's who told me the system has changed. You now have to get another form at the TUV testing station and then come back to the Traffic Police. He had a pile of such forms and full cards that he was sorting out for others. So off to the testing station. After some discussions with the security guy, laughing at my Turkish:D I finally discovered that the lady in the snack bar at the gate fills out the form for you. No problems there, 5 mins later and 15 TL lighter and then in the queue for the test. 5 HOURS LATER!!!!! ("because I had not booked an appointment"[

!][

!]) The car finally passed the test. The form was duly stamped and then told to go to Traffic Police for a new visa card.
This is the part now that I do not know what happens next for the following reason.
I enter the Traffic Police office at 4.45pm and say 'mehaba' to the 3 officers behind the desk and push forward the appropriate forms. Totally ignored. A lady pushes me aside and speaks to the officers who respond immediately. "Invisible am I?" say I, the conversation then continues as follows;
Officer - "You need to bring an interpreter" (In perfect English)
Me - "Why do I need an interpreter?"
Officer - "Because I do not know what you want" (In perfect English)
Me - "Arabam visa kart bitte, yeni visa kart lutfen" (passing him the forms)
Officer - (Raising voice) " Bring an interpreter, I do not know what you want"
Me - (In English) " Yes you do, these are the forms you have been sorting all day for the takobci's" (Showing him the forms and the full visa card)
At this stage one of the other officers leant across and screamed at me at the top of his voice "SPEAK TURKISH" I was somewhat taken aback at their attitude and this verbal assault and told the officer to go and have sex by himself:

This was a totally involuntary reaction on my part

I picked up my documents explaining that I thought they resembled large dark orifices

and left. Their shouting at me to 'return' made me realise that they did in fact understand English

and so I hurredly walked back to the car, without turning round, and drove off.
Conclusions
1. If there is anything owed or required regarding your vehicle you cannot book a visa inspection online.
2. If your visa card is full you need a form from the lady at the snack bar at the TUV station, cost 15TL, then have the test done and then take completed form and visa card to Traffic Police.
3. The Traffic Police are very rude, obstinate, obnoxious, obstropolis, aggressive etc etc, so deal with this part as you wish!
4. Fi is now going to have to go back again to see how they deal with her

If she gets the same treatment we will return with a translator to make an official complaint to their boss.
Have a nice day:D
