Fault Code P0621-01 - Generator Lamp....

[alcutler]

Hi, Just had a check done on my 04 1.9cdti and it came up with the following fault code - P0621 - 01 Generator Lamp "L" Control Circuit Malfunction - Any one have any idea what this may be - I recently changed the alternator and I think the battery may be on the way out now - could these be connected. Cleared the fault but re checked and its back again,
Thanks
