You are a star atzebmw
First time I did it and it was unsuccessful then I followed your advice and all good. Reset seat belt buckles faults etc in ISTA and all sorted now. Fault free car, safe to drive and ready for MOT
Second hand ACSM was around £80 from ebay with 'almost' next day delivery.
Thank you very much for all advice also to shawnsheridan on PM
