Thanks for all your support and kind words guys, it means alot. Unfortunately the VWCV guy is on holiday until 25th Apr and the Finance guy has just had a baby so is probably away for 2 weeks so I'll just have to go through what has now become a weekly routine of getting the VW assist Tech guy out Wednesday or Thursday, he will plug in to show same code. Then the rest of the day will be wasted waiting for recovery and replacement car to be dropped off.
As to what I'm going to do, I just don't know. I've spent between 8-10K on conversion which they say they haven't got to cover but I have not pressed this yet as I wanted it fixed but now I'm not sure if I even want to own a van. A replacement van is out of the question really, as I'm not willing to go through this and the hassle of converting again.
What I think I will do at this point is tell them I have been MORE than reasonable and given them more than enough opportunities to fix this which they have clearly shown they are not capable of fixing their own vehicles. I'll tell them I want all the money i paid for the van back and compensation for the money spent on the conversion. This is where I think I will hit a brick wall. So I think my only option then is to seek advise from the ombudsman as I have no idea of my rights in this situation. Fun times ahead me thinks.
