Has engine fault and needs attention. New ECU fitted, as old one damaged by water. After fitting ECU engine will fire up but will not die back to idle, will stall. Have had various diagnostics done and usual fuel filters and sensors cleaned and changed but still not working. Most likely cause is high pressure fuel pump failure. Selling as cannot get local garage to fix for me. Bonnet catch also needs fixing as pull lever detached / failed (wire still intact). MOT expired and vehicle on SORN so will need trailered. Standard Cayenne - with detachable tow-bar. Full service history up to ECU failure and have reports and receipts for diagnostics.
