My issue is finally resolved, I have a new Van. VW Corporate got involved and said I couldn't have my van back, I had a number of options given to me, including a new factory order but interestingly I wasn't allowed a 150 DSG, only a 204 DSG (at no cost to me) or a 150 manual. I could also choose from what vans were in UK stock and take what I wanted, this was the route I took and luckily my local dealer had the colour I wanted.
The van I purchased in May was an ex demo 66 plate Cherry Red T32 Highline, 150 DSG, the only options were composite media, app connect, and (dealer fit) ply Lining. I wasn't looking for a DSG but it was the right van at the right price for me. It had 3000 (ish) miles on the clock.
The van I picked was an unregistered MY18 Cherry Red T32 Highline, 150 Manual, with discovery media, front sensors, rear camera, electric folding mirrors, twin sliding doors, split rear seats with leatherette interior. As part of the deal I negotiated these dealer fit accessories: App Connect (as I already had it) roof rails, side bars, mud flaps and a full carpet 'wrap' rather than the basic ply lining, also the 5-year warranty. They also fitted the accessories I added to my previous van, wind deflectors on the front windows, rear bumper protector and rubber mats and paid for sign writing, 12 months tax and the costs to change my insurance.
All in all, I've fallen in sh*t and come out smelling of roses. I've been very impressed with both the dealer and in particular VW corporate who called me twice weekly to make sure I was happy, it seems to be a very specific fault I had (you can read my earlier post where I describe what happened) so I'm not sure if everybody posting here has exactly the same fault?
I went away from DSG because I had a loan van which was manual and honestly preferred it, mine was the first auto box I had and I didn't warm to it, also, I want to keep the van (currently company owned) and convert it so thought a manual would be cheaper to maintain in later life.
With regards to the MY18 vehicle, it feels completely different, smoother, quieter, more refined, strangely even the H4's seem a lot better, I'll post some pics I took pre-signwriting later.
