The missive that Denise/Lindbrook received from HQ was that only vehicles manufactured in 94,95 and a part of 96 plus Turbos in 96 were potentially affected. As someone mentioned earlier, perhaps the varioram engined cars denoted the unaffected and therefore it wasnt an issue from then to the end of the production run. Most research bits I can glean seem to tie the dates together.
