I have a 2011 V8 Vantage S Roadster. Was having convertible top issues...movement pause/failure, the the instrument cluster going off and on intermittently and several warnings coming up...air bag, tire pressure, emission system. All typical signs of a roof module failure. Replaced the module with a new one (not something from ebay) and had it programmed by a not-too-helpful Aston dealer. Now I'm seeing: instrument cluster dark on start-up but lights up after about 30 seconds to a minute. Roof movement pauses 3 or 4 times during open/close procedure. Air bag, tire pressure, etc warnings on the instrument cluster. The car starts and runs fine and the battery was replaced 18 months ago and stays on a CTEK when not being driven. Car is garage kept. Can anyone tell me what to check next and how to narrow this down? Terribly frustrating.
