| Disco_Mikey Member Since: 08 Apr 2012 Location: Dundee, Scotland Posts: 4532      | Also, the WSM doesn't list U0434 as a possible fault code for the ARCM   | ||

 Hi Simon I know this is an old thread but could i ask how you got this replacement configured, I have a TDV8 and have sourced and bought what looks like a TDV6 ARC module, I didn't know they needed programming so one step forward and two back unless the GAP IID can configure it How did you get this problem resolved? Kind regards Stuart | ||

| Simon_CSK Member Since: 21 Dec 2020 Location: East Ayrshire Posts: 70      | I would love to help but cannot remember which car it was. I have owned many RR Sports in the last three years and currently have 5 all of which are unlikely subjects as three of them are spares cars.
