The first time MMC fitted EZ power steering to +4 was 2013 I have the first car fitted i.e. the press car.
Do you know when MMC dropped offering EZ power steering system Keith and their source of replacement. I know power steering was an option on Roadster's until 2018 when 5 link rear suspension was introduced. I thought the type approval document for this change dated December 2017, may have offered some insight on sterring assistance but it simply includes the following under steering section:
7.2.2.1. A brief description of the electrical/electronic components (if any): None
7.2.3. Method of assistance (if any): None
The matching parts book offers no detail on power steering fitment either
