Hi Mate I assume tilford near Farnham? If so I am just down the road from you near Headley and GRAYSHOTT. I would keep it as it is but consider a road trip to msd and get it live mapped. I expect it has been chipped but they are much better properly mapped.
I had a VW Caddy 20vt a few yrs back and the owner of VW caddy forum lives in Farnham (Al)
