Adamw Posted August 15, 2022 Report Share Posted August 15, 2022 Yeah thats an odd one I havent seen before. Possibly a backfeed keeping the ecu alive during the power cycle step. Can you try again, but this time when you get to the step where it tells you to power cycle the ignition, try completely disconnecting ecu or disconnecting battery for about 10sec, then reconnect power before clicking the ok button to continue.

Joamini Posted August 15, 2022 Author Report Share Posted August 15, 2022 I tried and even longer. and also try an older version Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 15, 2022 Report Share Posted August 15, 2022 So you get the same error with older firmware? Not much else I can think of apart from returning it to Link for inspection and updating. Quote Link to comment Share on other sites More sharing options...
Joamini Posted August 15, 2022 Author Report Share Posted August 15, 2022 not good news, it can take time I imagine? I'm from belgium and the link was bought in holland Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 15, 2022 Report Share Posted August 15, 2022 It would go to our UK warehouse, they can inspect and possibly repair there. It would also be a good idea to try removing from the car and powering it up on the bench and try the firmware update just to eliminate wiring or power supply issue.

Joamini Posted August 15, 2022 Author Report Share Posted August 15, 2022 I tried again with older version. by physically disconnecting the ecu. always the same result. I am disgusted. I had some evidence with the car Quote Link to comment Share on other sites More sharing options...
Joamini Posted September 19, 2022 Author Report Share Posted September 19, 2022 hello, to follow up. My ecu came back. I can finally enjoy my car. Thanks for your help. Quote Link to comment Share on other sites More sharing options...
