There might be. I can't remember all the details at the moment, and my manual is at home. If memory serves, there is a certain pin missing on the engine test connector interface that was required when adjusting the mixture. While going through the lambda diagnostics section, there were a couple things that just didn't appear on the engine that were shown to on the US version. I will have to pull up the manual and try and remember the details. I am sure there is a mechanical adjustment, but (from bad memory again) the numbers I read were within spec so I didn't need adjustments.

This model is an early euro 1984. No leather, no grey plastic side panels, no plastic bumper covers (big heavy fiberglass airdams), old school 14" turbine type rims, no hydraulic suspension.
