hi roger i have been out and checked the car all afternoon and no hdc at all so seems to have cured it suppose time will tell but my hdc inactive was on everytime i turned the key then that led up to abs light,yellow triangle,hdc air suspension part of a failing battery it was as though the car was telling me it was poorly in a way try the connections were it meets the bulkhead where you can connect the jump leads etc thats were mine was loose hope this helps let me know how you get on
