Ok an update on this issue. parked the gal up for 4 days as was not needing it and battery went flat so I charged it up and put it back on. Engine was turning over but would not start so I took the battery back as it was only 18 mths old they tested it and came back and said that it was not delivering enough amps so they replaced it great I thought. So went home fitted replacement battery and it started first time but the issue i had before reappeared the car will not idle and is a real pain driving an auto that will not idle dangerous too. Last time after taking the car for a long drive of 100 miles the engine ecu seemed to reset it self and all was ok now that problem has come back surely you should not have to do this every time you disconnect the battery. Could the engine ECU have a fault? Is there anyone near me that could do a vag-com test for me? This is driving me nuts now as it is a lovely car to drive, but im scared to drive it while it does not idle. Any help would be greatly recieved. Regards Headnut
