Warranty on mine runs out this year too.
My advice would be to scour this forum for warranty claims made by owners - like the steering, roof corrosion, camper control unit, corroding alloys (check insides too), front doors sagging and rubbing on the sills, freshwater gauge, iPod connection sounding funny ... Just to double check that yours is ok in all these known problem areas. It will be a pain, I know, but I got stung on post warranty repairs on my Audi s5 that I could have avoided if I had learnt from other owners' warranty claims
I am also going to ask round my mates in the car trade as they will be aware of general T5 Issues. This is how I became aware of the door rubbing on the sills and corroding alloys for example. I have had both these attended to under warranty.
Then as discussed get a dealer to check it out.
Then ask yourself whether the Cali is worth the risk. We know the reliability/ build quality is crap. You will likely get hit by obscene repair bills for stupid parts failures. But I will probably hold onto mine as I haven't found another vehicle that is as suited to my needs and running a three year old one is more cost effective than running a new one.
