Holden Caprice 2011 Problems

The HSVi plate on your car suggests it was ordered with some off-line upgrades when it was bought new. This was pretty common among those buying brand-new Holdens but for budget or company-policy reasons, couldn’t stretch to an actual HSV. The modifications were done by a sister company to HSV, called HSVindividual but the modifications themselves weren’t necessarily that same ones found on a HSV vehicle. In fact, many of the mods were pretty pedestrian, including cargo-liners for utes and even roo-bars for Holden models.

Other common modifications included sunroofs and bigger wheels and tyres and although nobody seems to have a list of what codes meant what modifications, any code that starts with `EW’ seems to relates to alloy wheels. So I’d imagine the EWT relates to that. As for FAT, I can’t find any reference to it on any information source; perhaps it has something to do with the Automatic Transmission?
