hello everyone, im a newbie to the forum but checked it out for years. hope someone can shed some light on my immobilser issues,
my van is a 2004 connect 1.8tddi which i had a postal re map done from a guy on here years ago (75bhp is pretty poor),
my issues started recently when the flashing led started and various fault codes associated with it too. however the van cranked and started every time for a good 3 months.
this week it has not started on 2 separate occasions, but after quite a few goes with all 3 of my fully working keys it eventually started.
any suggestions as to why it still cranks and starts when the led is flashing like mad?
any ideas on which may be faulty components?
codes i have had have been 23 which is ecu id mismatch, 15 key not programmed into immo module, and 16 faulty link between immo module and ecu?
even with these codes its been starting and running.
once i got it going today it started about 90 times with random selection of my 3 keys then failed a few times.
im a bit worried ill be stuck somewhere when either the starter packs up from overuse or the battery fails before i get it going.
thanks in advance for any more info.
