Hi guys, I have an a3 8l facelift and I have just put in a symphony 2 a4 radio in it as I couldn't find a decent a3 one. I have just gone to recode it with my vcds cable and it won't seem to communicate with it. Strange as it is working as it should (can bus working correctly) other than it turns off when the engine is turned off, not when the key is removed. May be a separate issue (and probably is) but I recently had the car remapped at AMD Essex and this is the first time I have used VCDS since then. It now won't seem to communicate with any of the controllers unless the engine is running? But will not communicate with the radio at all as previously stated. Any thoughts as to why this might be? Nick.
